Hello, I'm running electricity from my house to a detached garage about 100' away. I will be using two (2) 1000 watt, HID grow lights which draw about 9amps each on a 120v and about 5amps on 240v. These lights will be running for 18 hours/day. I will also be running a small portable air conditioner, which will draw about 5amps on a 115v. I will also be running a couple of small fans, a light timer, and perhaps small other small items occasionally. The main breaker panel on my house is a 200amp cutler hammer. I've already dug an 18" trench
Could I use 2-2-2-4 aluminum quadruplex wire, ran through 1 1/4" PVC conduit
from the main breaker to the garage breaker panel or do I have to use copper wire?
If I have to use copper wire, can you tell me exactly the size and colors to get? I'm guessing there's 4 wires that need to be run through the conduit?
If I use the 2-2-2-4 aluminum quadruplex - does this get grounded at the garage through a grounding pole?
Would a 60amp breaker panel suffice on the garage or should I go 100amp? If I go 100amp, then it seems like I won't be able to use the 2-2-2-4 aluminum, because that's only rated for 90amp, correct?
I had one person tell me to use 240v 40amp circuits for the grow lights - they said this would save me a lot on electricity. Is this true? I mean how much? I'm not really concerned with electricity costs because I'm going to go solar in about 4 months. Can the 240v still work with the 60 or 100amp breaker panel? Does it change the type of wiring
I would need to get?
Any other tips?
