I need to wire 4 220 Volt Inverter ACs, a 220 Volt Water Heater, and a 220 Volt well pump. I'd like to have at least 2 empty spares. What type of BR Breaker box should I look for? Is something like a 12 space, 24 circuit 125 amp box ok?
I was recommended a GE 125 Amp outdoor copper bus 12 spaces 24 circuits model TLM1212RCU. One of the breakers recommended was a 50 amp 1 inch double pole model BR2GETHQP250.
A 12 space panel is a bit small, but OK for this job, given that you'll be using main lugs here. I would upsize to a 20 or 24 space unit though if at all possible -- as Harper said, "Spaces are cheap, regrets are expensive."
Whoever recommended you a GE panel, though, was silly, and that breaker P/N isn't even a valid Eaton part number! (The correct Eaton P/N for a 50A two-pole breaker for that panel is CL250, BTW, and the corresponding native GE breaker for that would be a THQL2150.) I'd just get something like a BR2424L125G for this (provided it's indoors -- the outdoor counterpart is a BR2424L125R, but you'll need to field fit the grounding bar yourself in that case).
Make sure you pull the bonding Z-strap in the new subpanel, and also torque all the panel and breaker lugs to manufacturer's specs with an inch-pound torque wrench!
