<div id="SafeStyles1671466351">I have neve heard that but I would connect the utility to the AC1 input as the window is quite narrow then the grid. The GTI was a piss poor way for trace to regulate “sell” current would ramp up & back down all day long. NOT necessary. BUT then again that old duffer; SH probably has more brain cells left then I do. <br class="" />

At that time they ran a 115Vac circuit (grid power) over to their house and connected grid power into AC Hot In terminal #! in their Trace SW 2512. This is correct as I see terminal #2 is labeled for generator power. </span></p>
