Hello and thanks for the great thread,

Quick question: I am running 10-4 from my main to my sub, the breaker I should be using is 30 amp or 40amp?

I just want to make sure it trips in case I go over board.

Thanks again

Hey guys I have a large custom lighting controller running two rooms my question is, one of my rooms is 50' from where the controller is. I really didnt want to buy a new controller and wire a new plug, etc. Can I make 50' runs out of 12 gauge romex from the lighting controller to the ballasts and it still be safe and work correctly? Does anyone make ballast power cords that long out the box?

That looks like a fpe panel.no quads available for it. U should be able to raise that right side up for a 240v breaker. Have an electrician look at it. U dont want to screw up ur phasing.

The picture is rotated 90 degrees to the left, so just to be sure, you mean slide the bottom over in order to have two adjacent spots open, yes? Presumably at least one of the breakers isn't even used given the splice, and I believe the center two on the right/bottom are connected, though I don't recall what goes to what. :/ *fail*

EDIT: *fail* The two connected breakers almost certainly go to the through wall AC which has it's own circuit and a... not normal plug, I'm unsure of the specific name at the moment. :/

Congrats bro and glad all is well.

yes you want two spaces opened by each other

If Its a black red white copper with a orange sheathe its 10/3 romex and should be on a 30 amp 2 pole breaker.

So, how can I figure out the available amperage to my box? It's an apartment, the lines seem to run to the meters and then some locked down "high voltage" boxes. Other than basing it on the size of the lines running into my box, I'm not really sure?

bibbles · Apr 6, 2014

The guage looks like 1 or 0, assuming "conductor diameter" includes the insulation.

Where the meter is located u should see a main double breaker with ur unit # on it (hopefully) and that is what is feeding ur sub panel in ur apartment. Max I would think is 100 amps if ur lucky

Hah, I looked earlier but didn't see the numbers - 100 amps 120-240 V.A.C.; 50 amps maximum - I assume this means 100 total, 50 max per breaker, yes?

I have a 3 phase 208v question for ya. This is based off 100 amp 3 phase subpanel just running lights.

I currently am running 2 powerboxs at 35 amps each on "legs" AB and CA and would like to add another powerbox to "legs" BC, that would also draw 35 amps.

On paper that gives me a balanced load of 70 amps on "legs" A,B,C.

Am I correct, @hiboy

U can put 100 amps each phase. Of course u should follow the 80% rule.

Yes u are correct!
U will be balanced nicely

I don't think that'll be an issue, but I'm gonna be checking things outside of the room today, and shuffling breakers around as needed. One more question: It looks like I'm gonna be using two 120v ACs (12amps/ea), rather than a single 240v unit (12amps), and I've been waffling between a single 50amp 240v circuit for everything, and two 30amp circuits, a 120v for the two ACs, and a 240v for my (4) lights and fans. I figure that if each AC is on a different phase, the load will effectively be the same as a single 240v unit, yeah? What would you suggest?

bibbles · Apr 10, 2014

Er, two ACs on opposite phases of the 50amp 240v circuit at 12amps each, rather than a single 240v unit pulling 12amps on both phases, versus giving them their own 30amp 120v circuit. If the former will work as I imagine, it'll save the time and money of running an additional circuit, as well as more evenly distribute the load, yes? I'd be pulling about 32amps on each phase with my lights and ACs, rather than 20 on each for the lights, plus 24 on one via the extra circuit.

EDIT: Hm, I need to check the amperage of the stuff outside of the room, if I can put the fridge, et al, on one phase, then the ACs on the other phase, it may actually work out better than splitting them between two phases... it would still be good to know if that'll work though! :D

Thanks again!

hiboy gave me permission to help you guys if he was busy. Sounds like you're gaining ground on figuring this out. Just a couple of thoughts..
After you get the 50 amp installed in your panel and run that to a new subpanel..you'll use a 30 amp double pole for your lights. That leaves room for either one 20amp double pole or 2 15amp 120v breakers. That will be up to your needs per appliance. There is no code for 30 amp 120v in a residential dwelling...it's either a 15 or 20 amp. I think the 20 amp double pole..being the better choice. Just make sure to be under your 80% usage rule..and if you use the 2 120volt breakers that they are in fact on different phases (i.e. stacked together...as it may be).
When I move old wiring around..especially in a panel, I try to disturb as little as possible, as old wiring has more risk of the sheath splitting or cracking. Best to not "jumble" around too much in there. Your panel should be balanced as is...Hiboy just wants to be sure that by moving everything up on the one side doesn't put it out of balance...as you know every other breaker on each side of your panel is at different phases...connected to different buses.
Hopefully the big guy will pop in to help confirm.

Frostynugman · Apr 11, 2014

Does anybody know of any savy electricians in Colorado that would install a sub panel. If someone could PM me asap that would be nice nothing major maybe like a 15 amp or 30 amp sub panel? Thanks all really need the help

Frostynugman · Apr 11, 2014

Found the electrician. thanks!
