No power 120 outlets

We were dry camping last weekend using solar panels to keep the batteries charged . We were going to use the microwave on generator power but no outlets had power . All the breakers are set . . I ran an extension cord in & plugged the microwave in; i worked just fine . Plugged in at home everything is fine. I have installed a P.I. 50 amp hard wired protector in. Could it be the ground that's the problem? The battery's were charging off the generator.

There are several things here that could be wrong.....especially since you have a 50 amp RV (which has two hot legs L1 and L2), plugged into a generator. We need a little more information to really ascertain where the problem could be.

First off, what generator are you using and how did you connect to it (ie what connection on the generator did you plug into and if/did you use some kind of adapter)

Did you notice an error code on your Progressive Industries protector when connected to the generator, and if so, what was the error code. The PI protector will shut off electricity to your RV if certain conditions exist in your connection to the generator.

I'm also confused a little by what I emboldened in blue above, as this seems to me to be a contradiction.

Thanks

I agree, a bit short on info here. The one thing I would suggest is checking is the breaker on the generate itself.

A plug-in outlet tester is very helpful, although not 100% true in all cases. Available for about 5 bucks at home centers, etc.

Your Champion generator has an open neutral and your P.I. EMS has detected this and is trying to protect your RV. You need to bond the neutral and ground in order for it to work. The link below does a good job of explaining this. I heard (but don't know for sure) that Yamaha generators can not be bonded in this manner. I do know that it can be done on Honda generators.

Sorry it took me so long to see your reply, but it appears tkarper14 has you fixed up, with a great explanation and link.

You can go to Progressive Industries website and download a user manual for your particular hard wired protector that also touches on the generator bonding plug as I copied this from one of their users manuals there. I think you may also have a switch to be able to bypass your protector....but don't quote me on that.

Just my 2 cents. I thought that a 50 amp plug was 240 volts. 120 volts on two separate legs to ground. When adapting to a 15 amp plug you have eliminated one leg of 120 volts. I believe one leg is for one air conditioner and the other leg is for the other air conditioner and the rest of the unit.

Not exactly, when you use a 50 amp female to 30 amp male adapter, what the adapter does is jumps the only ONE 30 amp 120 volt leg over to both the L1 and L2 sides...so that way both legs are powered in the 50 amp RV....but they are sharing the same 30 amps L1.

This schematic may help as you can see the jumper/adapter on the far right to understand how it works. I do not like the way it says "split" as it's actually "shared" between the L1 and L2...but you can get the gist.


The OP is adapting from 50 amps to 15 amps on his generator, but it still all works the same. He is going to be sharing the L1 15 amps across both his L1 and L2 in his RV. Everything is powered.....but just at 15 amps (1800 watts) total

I didn't realize the 50a to 30a adaptor jumps the two hot legs together. Thanks for the info.

You are very welcome. This has been a great little thread discussion, and I should probably copy/sticky it somewhere, as this generator problem does come up here in the forums time to time.

Sorry I didn't get to make the plug for the generator & try it . I ended up replacing all the spring shackles & bushing & also the a complete brake job on the 5th wheel. Repacked the wheel bearing to.
