    Default Electrical question...Need assistance

    I already did this so tell me if I'm going to have issues. I have 3 LOR boxes, on each one where the 2 plugs come out of the LOR box, I plugged both cords into a triple tap then ran an extention cord into the tap. From there, ran the extention cord into 1 resectable in the garage which is a dedicated 20A outlet. Did this 3 times into 3 seperate outlets. I turned the lights on last night which is about 50% up. Didn't have issues. Now these are all LED's, this should be ok right? Or does both of them power plugs need to go into the outlet?

    If it's a dumb question, please say so

    That is certainly not a dumb question. If all you have is a few LED strings per box then you should be okay. The 50% power output has little bearing on the total current draw due to a thing called pulse width modulation which the triac uses to control voltage. If I understand correctly, you have a total of 3 LOR boxes per 20 amp with a few LED strings per channel? If so, you should be fine.

    What you appear to have done, sir, is effectively convert the boxes into a single cord box. A single cord LOR box has, obviously, only one input power cord, because internally there are two jumpers bringing 120vac hot and neutral from channels 9-16 over to channels 1-8, effectively plugging both cords into the same cube tap, only internally. Since the internal jumpers are after the left size fuse, the whole controller power draw cannot exceed 15 amps, or you'll blow at least the left side fuse.

    With LED's that shouldn't be a problem. If all 3 receptacles you are using are on the same circuit breaker, with LED's that shouldn't be a problem, not with the average 60 light string current draw of .04 amps; you need 100 strings to get to 4 amps, or leaving a little safety factor in it, that would be 1,000 strings of 60's per controller, or 60,000 lights per controller.

    If you're exceeding that, I'd really like to see your display. But then, I'd like to see your display anyway.

    Last year I had over 40,000 LEDs in my display. Almost all of my LOR boxes I have converted to a single power input cord (haven't gotten around to doing them all yet).

    Only used 3 15 amp outlets for my entire display, which used a total of 19 amps for everything

    You should be fine

    What gauge wire is the extension cord?

    Extention cords are 16/3 I believe. They are the normal green one's you see everywhere, light duty.

    There's no way I will exceed 15a. Not even close. I may be 5 or 6 (if that). Will calculate that tonight now that most everything is set up and in place.

    Thanks for the quick responses guys!
