I have an AC500 with daily full solar input and the NEMA 14-50R outlet connected to a Reliance Controls 10-circuit manual transfer switch SS2-50P inlet. This is pretty good offsetting 10 of my home branch circuits, but I never come anywhere near the 50A limit and I was looking to install another transfer switch but 30A for some other branch circuits in the house that are basically lights and other small loads. I noticed that the L14-30R and TT-30R outlets on the AC500 are active at the same time as the 14-50R outlet. Would I be ok to use those outputs into another transfer switch as long as I don’t exceed the 50A overall limit of the AC500? I was looking into it and I saw the topic of “parallel neutrals” come up but I’m not sure yet what that is or if it comes into play here. Each transfer switch would have a neutral bonded to the neutral/ground bus bar in the house load centre. Thanks!

@OhioIsEveryWhere A transfer switch can be installed, as long as it does not exceed the total output power of the machine. It is best not to tie the transfer switch’s neutral line together with the distribution box’s neutral line.
The response does not address my question, and you are incorrect about the neutral line. It certainly SHOULD be tied to the house load centre neutral line along with the ground line.
