I have a Midnite 60A manual transfer switch. I simply want to use it to allow me to bypass 120V grid power around a Victron Quattro inverter I am putting in while I am testing/installing it. I have a 120V circuit that has L1, neutral, and ground. L1 connects to circuit breaker and neutral to the neutral busbar in the enclosure but what about the ground? There is a single chassis ground in the enclosure but no ground busbar. Are they expecting you to just use a winged wire connector to continue the ground on if the inverter is bypassed?
