Ok, I'm really puzzled about this. When I connect 30/50 amp to shore power at campgrounds, all is well. When I connect to 15 amp at home all is well, however, when I connect to 30 amp at home, it trips the circut breaker. Circut breaker is new and and 30 amp plug is installed correctly, according to my electrician. When genset runs, all is well for 30 amp. Any help would be greatly appreciated

What are you trying to run at home. Both AC at the same time will trip it for example.

I have the A/C units off and only the microwave and sat TV box on. Elec water heater, fridge, heater, all off.

Verify that the electrician did not get confused and wire the outlet as a 220 Dryer or Air Conditioner receptical. The 30 amp RV plug is only 110 volts.

I believe Neil has the correct answer. You may also want to make sure the polarity is not reversed.

Hi TwoOfUs,

Sometimes it helps if you include your RV Make / model in your post. If you put that info in your signature you will not have to relist it on all your posts.

You say you do not have a problem on 50/30 Amp service in a campground. You don't say if your coach is 30 or 50 Amps. You run on 15 Amps ok at home. What is the amp rating of the new circuit braker (on your 30 Amp service) at your house?

Your electrician is correct; a 30 Amp plug is simple to wire as you are dealing with one leg hot, and a neutral & ground running off the same buss. To get 220 volts you would have to take power from two separate 110 volt buss's and 30 Amp receptacles don't have two hot blades like 50 Amp receptacles to attach the two hot wires to. Did your electrician run any other receptacles off that new breaker or is it dedicated to the 30 Amp receptacle?

Sorry to ask so many questions; but we need to eliminate some of the simple stuff in order to ask better questions.

Green lights and soft breezes,

that don't sound right. Get ahold of that electrican fast and have it correct it. The last thing you need is to burn up your coach if you leave it unattented with your a.c going and microwave and sat going .. just my 2 cents

Two,

Is the 30 amp home plug wired correctly at 120V or 240V, i.e. is it wired 10-2 w/ground, or 10-3 w/ground. If wired at 240V and you are using a 30 Amp 120V line cord, you would be creating a dead short.

Thank you!

All-
Well, let me see if I can answer somne of ya'lls questions.
Definitly wired for 110 and not 220, the electrician asked me more than once to confirm that's what I wanted. The new breaker is 30 amp. I got the 30 amp receptical and box from Camping World.
The coach is set-up for 50 amp but I wanted a 30 amp at the house since I don't need to run both A/C units - even when we have guests.
Appreciate all the input folks. I always figure the more heads you got thinkin' on something the better the answer is going to be.

Which breaker trips? Motorhome or at the house's panel?

LVJ58 · 04-14-2007, 04:32 PM

Is it just possible that you may have gotten a "faulty" NEW 30 amp circuit breaker??

Just a thought, Jim

TwoOfUs · 04-14-2007, 05:12 PM

It's the breaker in the house panel. This is the second new breaker, and still, trips when I plug in the MH power cord.
I had this happen at a campground once, the maint guy came and replace the breaker with some sort of ground fault(?) breaker, but that's the only time I ever had a problem at the campgrounds. Just here at the house.
