Re: OT - Simple Disconnect/Isolation Switch

Make the load common though the DPDT isolation relay. The coil is connected to the utility/genset line on the ATS output side.

This meets your condition of not having both AC sources connected at the same time, under any circumstance.

It's either one or the other...

Thanks John,

However in this case, the Alternate AC source (PV) can work in tandem with the utility side, however the Generator will not play so well.
