Txsteve,
thx for the reply. I'm new to the electricity lingo world but know the basics. I have a few follow up questions if you don't mind. What actually makes the 240V versus 120V better and how does one "balance" the circuits? For example, if someone was using 120v and just ran their S9 miner at home off a standard 15amp circuit, how does the balancing come into play? Thanks again
if you are just running 1 miner it's probably no problem if nothing else on circuit, but when you have multiple PSU's on 120v circuit they get randomly plugged into either the A or B 120v leg -- if you are running multiple heavy loads 24/7 you want to make sure the amp draw is about the same on both legs. You can use an ammeter in the panel to check it, and make adjustments
when I was on 120v, after a close call(blew the meter up) with unbalanced legs, I mapped out each circuit. I was running titans which require 2 psu, so I plugged 1 psu into each leg. So no matter how I turned the rigs on and off I was still balanced.
with 240v you don't have to worry about balancing because it draws 120v equally from each leg
And I wouldn't want to use a 15a circuit, use 20a #12 wire drawing no more than 16a continuous
you really should talk to an electrician, because running this stuff 24/7 you don't want to even be close to maxed out. And put an ammeter on any circuit in the panel than is running a miner to make sure you aren't drawing too many amps on that circuit
oh you also want to make sure you are using heavy duty 20a recepatacles and not the standard light duty residential receptacles. I have a laser temp gun and walk around reading temps of receptacles, plugs, psus, etc -- anything that is hot is a problem, especially a light duty receptacle in a wall that's hot !!
