When you are planning out power distribution for your setups, there are a few things that you are figuring out simultaneously. And it's a really good idea to do this ahead of time so you don't run into problems on set. So you need to figure out what equipment you need and where it goes. And you need to do that based on how much power you need in any given place on the set. And so for the scenario power distribution feature, we've created a way to do all of those simultaneously. So the best place to start is in your diagram details. So to open your diagram details, just open details without anything selected here. And you're going to make sure that you have the right region stuff selected. Your power system is just uh where in the world you're doing this. So, are you going to work off the American, North American 60 Hz, 120 volt standard or the global 50 Hz, 230 volt standard? The frequency doesn't actually matter that much. We don't use it anywhere, but the base voltage is important. Um, and then the length units. Now, these are both based on the visibility sidebar setting here, but these two settings are still separate. When you create the diagram, if you have feet selected, the imperial measurement, uh it's going to automatically select 60 Hz, uh 120 volts, and feet for the length units. And if you have meters selected, it's going to select the metric units. Um, but you can change these for any diagram if you're working in different places. And you can still change this at any time without changing uh the diagram settings. This is going to show um the lengths on the diagram. This is going to calculate power and then also decide how to divide up your equipment. More on that in a little bit. So after you have set up your region settings here, we can go ahead and start adding items. So we have two new categories here. Uh three uh four. One is uh we have electric, which includes all of the stuff that we've added. But right now we want a power source because that's the first thing we want. Let's go ahead and add a generator trailer. Um just as a as a way to start. We can change that later and we'll see how in a minute. And at that point you can switch over to let's say we want to switch over to DRO. Um so because I have the America region selected this is what I see. If I had the global region selected, then I would see different equipment here. I would see more C4 boxes, that type of thing. Um, and same with cables. So, uh, you'll see what you need to use in the region that you've selected. Let's start with a 600 amp DRO box. And here we have it. So, you see in our DRO box, uh, we have our line side cable and our load side cable. And then we can we can rotate it. Uh the line side cable will always come out here and then load side. Uh if there's a pass through cable, it'll come out the opposite side from line side and the other cables will come out the sides. U but they adjust themselves. So you don't really need to worry about where that happens. And then all you need to do to connect connect them is make sure that snap is on and drag to connect. Now we have a cable and no matter where I move this, the cable's going to follow. Now, we can see that this trailer here, this generator, if I go to its details, it's autodetecting size. Uh, I'm going to turn that off for now. Uh, and then it also has three-phase distribution. We can switch it to single phase if we want. We're going to leave it in three-phase for now because that determines the phases of everything that gets plugged into it. Now, with this, we want to start plugging in some heads. Now, the 600 amp box, as you know, has some base cables. So, we can go in and plug in a 10K. Um, fixtures don't automatically have cables plugged into them. But now, if you rightclick and plug in, we make a cable for you. And then that works the same way. Connected to the box. You can see that my amps updated here, and they updated here. And if you were to look at this cable, you would also see that they have updated here. If you want to show calculations for any given item, go ahead and just show the name label and it's going to show you what's on there. Now, for cables, you can see that we also calculate line loss. Not a very long cable. Um, and this is right now is five number two. So, not a ton of line loss. Uh, but if we made the cable run long enough, then you'd start to see it. So if you drag this out, you can see that that uh that line loss is coming up a little bit. And if we make it very long, let's say if we moved it way out here, then we'd most certainly end up with some line loss. Now we're getting there. So it can go a while. A cool thing about cables is that you can choose how uh which lengths of cable you want to use. So by default for uh the American uh for the med the imperial standard we have 15 25 ft selected. But you can say well I actually have 100 foot cables. I want to include those. And what's going to happen is um the cable is going to divide itself up based on what you have available, which is really useful. Um and you can use little jumpers if you want as well. And what that does is it determines how we add up your gear list. Uh we'll do more on that in a little bit. But one thing you can see here is that um we have uh number two five wire 50footers and 25 footers and it's showing me how many I've used here. Now this is list. So this is an auto update list. So it's just going to update with whatever I put on here. Um if you switch it to manual update, then you can work off of a set list. it will still compare the two because it'll be calculating what length of cable that you have used. Okay, so let's move this back here so we can see what we're doing patching things in. If for any of these items you turn off the name label, it'll just show you the phases on the item so you can always keep track of what's what. We'll go ahead and keep it on for that so we can see line loss. And let's move that up here so it's easy to see what's what. Now we have our 10K plugged in here. One thing you'll also be able to see is if you dim the intensity, it will take the amperage down. That's not obviously always a onetoone relationship. We've built it as one to one for now and in the future maybe we will update that, but it'll help you to uh to adjust things if you know you're going to work off of everything dimmed down. So, let's plug in a 5k to our uh 600 amp box here. And those of you who know will know that a 5k typically uses a 60 amps cable. So, I'm going to plug it in. And you see it's yellow to connect a box. This plug is not compatible because 600 boxes usually have 100 amps cable and not a 60 amp baits port. So, what we can do here, we can plug it in directly. if that's good enough, uh, if you just are trying to illustrate this. But if you want to be really exact, what you can do is you can add a splitter. Um, and so what I'm going to do here now is also show you that for every electrical item, if you rightclick, uh, you'll see that you will be able to add everything that is actually compatible with the ports available on this item. So we know that we need 162er. Just put that right there. Then we know that we can plug that baits cable into that. And now that's also on our list. So you can get really really detailed about what we're doing here. Another thing to notice is that this twofer when I plugged it in automatically selected the uh the Bphase because that had uh less amperage on it than A. So whenever you plug something in, it's going to select the the phase with the lowest amperage. And as you add other things, it's just going to continue selecting them. You see that? Added it to red. And this one should also add to red. But now, okay. So, so that's showing that the amps are over limit for the auto detected uh the autodetected cable. So, if you want to turn off auto detect, then you can you can do that. And uh it'll allow you to actually select um select which cable you want this to be. So maybe we want this to be an L630. Now the plugs aren't compatible there, but uh you get the idea. Uh you could use um you could use a box where that has L630 outputs, a stage box. Okay. So now that we have done all this, we can get into more of the actual branching logic. So let's see if we want to add a box. Let's say 100 launch box. That's pretty common. So we can add it there. We can add boxes directly from another box and it will add the cable in between them automatically. Check this out. Can choose to patch this over here. And you can see that we can just really quickly move stuff around. If I want to duplicate this, I can do that. The cables will always react to where you're where you're moving things around. We have our singlephase box here, so it's only showing one phase. And another cool thing that you can do with cables is that you can run them really precisely. You know, a direct pointto-oint cable run is super rare. Uh, and so what you can do is add control points just like you do with uh with our arrows. And so, you know, presumably if you're running there and this cable, you want it to go here. And then probably want another point over here to make it nice. And you know what? You can actually change the point type. It's curved by default, but if you switch it to these little points, you can get some some like nice tight corners. And that way you can keep it going exactly where it wants to go. And as you can see, it is always calculating where those uh where those lengths go based on what you have selected here. One other thing you can do with cables here is integrated wiring. So this is kind of a very specific thing that you would do. Um, and let's illustrate this actually with another type of item you can add, which is a power load. So power load isn't anything specific. It is actually just a an adjustable amperage. It's going to give you 10 amps by default. That's fine. But if you want to account for and you don't know exactly what it's going to be, but you want to leave space for it in your DRO, you can just add a power load. And this will plug in there, that's fine. And then with the load itself, you can adjust the amperage. Let's say 18. Why not? The amps are near the limit on this, but not over. And then with this cable, we can turn on integrated wiring. Now you see this has become dotted. What this is effectively for is when you have wiring that isn't necessarily going to be um you know a single extension or a bait cable or a cam lock or something along those lines. It's going to be hardwired or something. This is also great for uh if you really want to map out a uh like a location wiring and the different circuits that are built into the walls, you can use this because what happens is when you deselect this, it disappears, but it's still connected. So, you can see that the when I select this, you'll be able to see it. You'll be able to um to make changes to it. But when I change this, our amperage here still changes, but we're not cluttering up the diagram with a bunch of cables that in reality you wouldn't really even be able to see. So that is a nice quick way to do that. There's a lot of flexibility here. And what we're looking to do is make it so that you can thoroughly plan out everything you need to do. But the last thing that we know is that some people don't need to see this. If you're a DP or director, even a gaffer, sometimes you don't really need to see where all the power is going to be. And so in a visibility table at any time, you can just go and turn off power distribution. Just hide it. All that goes away. But only for you. anybody else who's actually working on that um can see it and can look at it, but you can focus on the things you need to focus on and it's always there if you need to take a look. So that is power distribution. It's extremely powerful, so to speak. Um and it's going to help uh save a lot of time on set.
Diagram region settings
You work in different places, so each Diagram has its own settings for “Region.” In the Diagram editor, open the Details sidebar with no item selected to see the Diagram details. In the Region section, choose two properties:
Power system - which standard is your power?
Choose between America (120V 60Hz) and Global (230V 50Hz)
Length units - how do you measure your equipment?
Choose feet or meters
This applies to the measurements of equipment on your List, but does NOT determine the measurements you see on the Diagram itself (that’s still the setting in the Visibility sidebar)
When you create a new Diagram, these values are set based on your device’s setting for feet/meters in Visibility (feet defaults to America, meters to Global)
The equipment that’s visible in the Scenario library changes depending on which power system is selected, so we recommend you choose your electrical standard before adding distro to the Diagram
Auto-detect
Power Sources, Boxes, and Cables have the “auto-detect” property: the ability to read what’s plugged into them, and automatically choose the size required to handle the amperage.
On - recommended if you can order any equipment you want, based on your power needs. Items will size up and down based on load.
Off - better if you’re working from a preset gear list or existing distro run. Displays warnings and alerts, instead of changing size.
Calculations and labels
Each item can show its own amperage values, because amperage is calculated at every point in the distro run.
To view calculated values, display the item’s text label
Three-phase Cables will display the calculated Neutral amperage as well; others will only display Hots’ amperage
Hiding the text label will not display amperage, but overages will still be calculated (and show warnings), and assigned phases will be displayed as dots
Cable and Splitter labels are hidden by default; Boxes and Power Sources are visible
Warnings and alerts
Items will display a warning (yellow color) or alert (red color) if:
Amperage is exceeded (alert at max, or a warning at 90%+ of maximum)
Voltage is out of acceptable range (warning at 5% under or over; alert at 10% under or 6% over base voltage)
More than 3% voltage drop from line loss (warning only)
Cable ports are not compatible (warning only)
Connecting items
Connecting power distro items follows the same rules as connecting other items: to connect, the feature must be enabled (use the N key), or you can hold Shift to enable it temporarily while you drag.
See Snap, Targeting, Connection for more details.
Power Source
The heart of your distribution is your power source – or in many cases, sources. You can add as many as you need on a Diagram, and they determine the settings for the entire distro run that gets connected to them.
Size - the capacity of the generator, measured in total amps
Select “Custom” to define a more specific amperage that’s not listed in the drop-down
Housing - the form factor of the generator (trailer, van, etc … or an abstract box)
Different housings are available for different amperage ranges
Distribution system - configure the available phases
All Sources can have single-phase for the America standard, and most have 3-phase available
100-200amp power drops on the America standard also have 120/240V split-phase available, for household power
Adjust - most generators allow adjusting the source voltage, to counteract line loss from a long initial feeder run
Power Sources can be positioned, rotated, and scaled, and then connected with Cables to other items.
Box
Boxes represent distro boxes, which take larger line-side Cables and break them out into smaller load-side Cables. They provide a way to convert between different cable ports, and strategically prepare for power needs.
A Box has one line-side Cable port, and various load-side Cable ports. These determine “port compatibility” based on common Box configurations.
Incompatible ports will show a warning, but will not prevent you from connecting Cables. It’s flexible, but pay attention to any yellow boxes you see!
These are represented by quick-add blue buttons that appear when you select a Box; to add a Cable, click and drag one of these (you can drag it directly to where you’d like to attach it).
Moving or rotating a Box will move all attached Cables’ endpoints.
Deleting a Box will delete all its connected Cables.
Boxes can be added from the quick items in the top left, or by using the B key.
Cable
Cables connect all other item types together. They behave like Arrows as multi-point paths, so you can ensure that they’re run exactly where they need to go.
Drag either end to scale the whole Cable, and plug into compatible items.
The line-side can plug into Power Sources, Boxes, and Splitters
The load-side can plug into Boxes, Splitters, Fixtures, and Power Loads
Cable lengths - select what lengths of Cable this run can use
The chosen lengths will be used to make up the Cable’s distance, favoring the longest possible; the end of each length will be marked with a plug symbol
Units of measure are defined by the Diagram’s region settings
These lengths will be counted to build your gear list (see below)
Cable phase(s) - like picking which port to plug into
Available phases are determined by the line-side cable, which is ultimately defined by the Power Source
When plugging in new Cables to a Box, they’ll automatically be assigned to the phase with the lowest amperage
Add control points using the (+) buttons, and choose their style from the bottom actions:
Curve (default)
Corner
Figure 8 - if you want to plan to keep slack available
Ballast - show a ballast or other box inline, without adding extra items
Integrated wiring
In some cases, showing wiring on the Diagram is unnecessary, but calculating amperage is still valuable. (For example: wall outlet wiring in houses, or fixtures integrated in the set.)
In the Cable Details, enable the “Integrated wiring” switch
The Cable will be hidden, unless a connected item is selected (then the Cable will be shown and can be selected)
Splitter
Details are important, and showing up without the right splitters can be catastrophic for the whole set.
Splitters connect to both Boxes and Cables, as needed
Break out multi-cable like Socopex, or twofers like Bates or CEEform
Contextual menus
Based on their cable ports, all items have a certain set of compatible items. When building distro runs from Power Source, working towards the load side,
Right-click or long-press to show the contextual menu
At the top, view options to add any Box, Cable, or Splitter that’s compatible with the selected box
Connecting fixtures
The total amperage on a distro run is the sum of the amperage pushed by connected Fixtures.
Each Fixture has a wattage value (for both built-in and Cloud Library Fixtures)
Amperage is calculated based on the voltage (after line loss)
To connect a Fixture:
Right-click on the Fixture and select “Plug In” to create a Cable
Drag the load-side of a Cable from a Box to connect it
Power Load
There are some cases where a specific item isn’t required, but you know you’ll need to account for power draw. (For example: Kraft Services, HMU)
Add a Power Load from the library and plug it into the distro run
Set the amperage for the Load (note the Load resizes based on amperage)
This will be included in your calculations
Items on lists
One of the most powerful reasons to build your distro this way is to get accurate counts for equipment lists. If your distances are correct, you’ll know exactly what Cables, Boxes, and Splitters you’ll need to do your setup; plus, how large a generator you require.
See Lists for how to connect to Diagrams
Build your distro run from scratch, or from a pre-existing List
Scenario will automatically build your List (if auto-updating), or compare with an existing list (if manually-updating).
This includes counting all Cable lengths as they get used in different places
