OK, Ive installed a combo, wind turbine/solar power system, and it's time to Go live. Few problems, I'm not really understanding how to wire my QO sub panel. This has a mechanical interlock in it, so I can switch from GREEN power(from my inverter) to Grid power. Now inside this Sub panel, there are 3 bus bars 2 H and 1 N. I have 6# wires run from main Panel (off a single pole of a 60 amp double pole breaker) to an external disconnect (required by utility) which then comes inside to another 60Amp breaker (inside disconnect) BTW ALL THIS IS ONLY 120 V and all the diagrams i see are 240V. from this 60 amp I have the hot and neutral jumped to the QO sub panel ( its a Square D by Schneider, 4 Spot 60Amp) the other side the breaker is the AC in to my inverter. NOW how the heck do I wire my sub Panel???? I have Hots from both my inverter and from MAIN, but I want inverter output to power sub with the ability to switch to Grid power... I'm so confused
