I live in a mountainous area with a lot of snow that takes down power lines frequently. The last owners of the house installed a transfer switch and have a Honda EX 4500 generator that previously powered the entire house (100 Amp service) as long we were judicious about our usage while on generator power. The last two times we've lost power the generator only has powered one of the two sub panels. Both sub panels have QO Square D Surgebreakers (QO2175SB) on them. When we're on utility power, both surgebreakers' LED lights are green. When the transfer switch is set to generator power and generator is on, only one subpanel has power and the Square D green LED on that panel is on. There is no power to any of the breakers on the other subpanel and the Square D unit is unlit. Is it possible that the Square D is causing the issue or should I be looking elsewhere? Other suggestions?
