One or two generators?

I think I follow that the gen's receptacles have a circuit breaker in line, and the cable that connects the two gens to the RV power cable doesn't, right? At least I'm guessing what 'banana cables' are.

My Yamahas have a black adapter thingie that plugs into both gens, and gives me a place to plug in my 30 amp cable. It doesn't have any fuses as far as I know. Don't see where they could be.

I've been using that even if only one gen is running.

The Yamaha may have a different setup from the Honda.

On the Honda, there are two 120V outputs -- the receptacles which are protected by a breaker, and the 4mm banana plug outputs, which are not protected.

The commercial kits for running in parallel of the banana plugs have a breaker on the 30A circuit, and the instructions for a home built should also include inclusion of a breaker.

The frequency sensing capability works on both outputs. When firing up Gen2, if it senses power from Gen1 across the bus before Gen2's inverter comes online, Gen2 will match the frequency already present (and be a slave to Gen1).

If you power down Gen1, at some point Gen2 figures it out and becomes the master. IF Gen1 is restarted later, the same sensing process works in reverse; when Gen1 senses power from Gen2, it becomes a slave to Gen2.

At least that's my understanding from the last eight years of owning my twins...

If you do have a plug going off the receptacles, be sure that the polarity is correct.
