Edit: This is for a 120V only generator.
I plan on having an electrician install an Interlock kit onto my electric panel. They will install a 30A 125/250VAC L14-30 inlet box on my house to a new 30A breaker for a proper 120/240V generator. My plan is to use one of those jumper cables that tie the two hots together so I can utilize both sides of the panel.
I am aware of the potential pitfalls of this. No 240V circuit breakers will be turned on (* except possibly one, which is my question below) and will have the electrician verify I have no MWBC’s in my house. We will remediate them as necessary.
So all that’s well and good. I think I did my homework on how to make this happen, but I have one caveat… my Sense monitor. I would prefer to keep this on when using my generator so I can see the power usage of that too.
My question is:
In light of the fact that I will be tieing both hot wires together from the generator, what would happen if I allowed this double pole circuit breaker to remain active for monitoring?
- Will Sense work just fine?
- Will it not work, even though the power draw is minimal?
- Worst case: Does something very bad happen by allowing a double pole breaker to remain active during this generator use? I assume the Sense monitor doesn’t bridge anything together, does it?
I don’t think the Sense device is a true 240V device, even though it requires that double-pole breaker. My concern is more about leaving a double-pole breaker active in this scenario. Also, will dual fed 120V lines hurt the Sense monitor in this way?
