Generator Interlock

[Deerslayersh]

While we’re here, can someone tell me if I am able to feed both sides of my electric box with a 120v generator plug?

Obviously I can’t run any 240v appliances, but if I had all 240 breakers turned off would it be safe and possible to split at the inlet plug and lower each side of the panel?

Anyone draw a quick sketch of what that’d look like? Plugging into to a 3 prong RV plug on the generator.

If I’m understanding you correctly you want to use a single phase generator, (120V) for one leg and get another generator for the second leg?
IF and only IF your not running anything 220 like you stated you can jumper one lug to the other and use one generator. Now that isn’t the correct way of doing things, but if your in a pinch it works.

That being said, you’ll need to make sure your not pulling more amps than your feed wire can handle. You shouldn’t do things like I stated above if you don’t have the knowledge to double check your work with a clamp on meter / voltage meter.

I wouldn’t run two generators only cuz the phases would have to be in sync, if they aren’t that be ugly! That’s a can on worms you don’t wanna open

Sorry for the confusion. I'm asking about what you explained in your first 2 paragraphs - running both sides of the box with ONE generator. Thanks for the explanation.

It can be done because I did it during the snow storm in Feb.

Dad walked me through it over the phone.
All I can remember is it involved using a jumper wire on one of the double pole breakers to make both legs feed off of the generator.
I think it is only something you want to do in a pinch but maybe an electrician will chime in.
