Calculate total amps required

[rposgood]

How many amps does an average display require? I live in a house with only 2-3 15 amp circuits available to run extension cords from. Would this typically be enough?

I run my entire display on three 15amp circuits.  I have several inflatables to take up more than half the current.  You don't need to run at full power.  I don't have any strings above 70% and others run between 30% to 60% depending on what I need to keep from blowing 5amp fuses.

Here is a list of my show. I keep records of everything I'm running. at the bottom is a total of my amps and watts Need to remember all these numbers are at 12 volts with all lights on white at 100% I was told that watts never change so if that is true my show only runs at 24 amps. I running 2 20 amp circuits. I have a meter on my big tree. as per specs that come with the lights I could hit 90 amps but I have never seen it go over 20 amps.  Yes my matrix has no numbers. its only 5 volts but I cant find any specs for the panels.  The big thing you need to watch out for is gauge size of wire feeding the power supplies.

When I was still running all LED lights, I could have run my whole display on a single 15amp circuit with room to spare.  But I used at least 3 circuits just because it lessened my need for extension cords.  I have more lights today but 100% pixels and I suspect I could still run my display from a single 15amp circuit, but I am now connected to 4 outside outlets (separate circuits) just because it is easier.  Back in the incan days I could not even run all my minitrees from one circuit.  LOL

Thanks for the feedback. I appreciate it.

I have about 2500 total lights.   It is a mix of incandescents (c9 & mini) and LED (bullets & floods).  I use one Renard 24 board.  I just checked last night and it was 12.56 amps.
