No 110 power 3150BH

[handlepuller]

I plugged into a 30 amp outlet that I probably shouldn’t have. Ever since doing so, I don’t have any 110 power to my unit. My cord is good. I can run off my battery, but I don’t get anything on the 110 system. I checked all of my breakers, and none of them are tripped. They never did trip but I obviously have a disconnect somewhere. GFI is reset. Any ideas?

Assuming you plugged into a mis-wired 30A plug that was wired with 240V, everything 110V in your trailer is probably gone.

Yikes. I’ll find out after I bring it in on 6/4. The refrig still works on propane fir what that’s worth.

If accidentally plugged into 30 amp 240v, where 120v phase was applied to the neutral line, I would think that any unused receptacles should survive and be live if now plugged into 120v The appliances (fridge, AC, converter, water heater etc) would likely be damaged but receptacles shouldn’t be damaged. I would love to be there and 5 minutes with a VOM I could diagnose the fault.

When the fridge is running on propane, it uses 12VDC. It has nothing to do with AC power.

Other than checking the appropriate breaker/fuse, there is no way to diagnose an AC or DC problem in a trailer without a VOM. There are lots of questions regarding power problems on this forum, and I sympathize with new trailer owners on these issues. If I had one piece of maintenance advice to give these new owners it would be buy a VOM and learn the very basics of how to use it.

As a licensed electrician, here's what I did to resolve most problems and keep track of my amperage draw on 30 amp service...

Frank,

Nice simple read outs.

I installed a progressive industries EMS-HW50C hardwired EMS behind the breaker panel. I have a remote display mounted in the basement by the water panel and another in the RV by the breaker panel. I can monitor voltage and current on each leg and if the EMS detects a fault it will display the fault on the digital display.

I originally had a portable plug in model but felt the Hard Wired was simpler since it’s out of sight and permanent mounted.

It has saved me multiple times. Mostly due to low voltage when at an old Campground. It will disconnect power to the RV for 2 minutes if it senses a low voltage and then try again. If it senses a miss wired outlet it will not pass power to the RV and will display a fault code.

If the OP had one he wouldn’t be in this predicament.

Have you actually reset all the breakers? They can look good but be tripped. Turn each fully off and then to on to reset them properly. The other place to check is the power plug on the side of the trailer. Remove the 4 outside screws and carefully pull it of the side. Check the wiring there. There have been posts on lose connections being found there.

I did all those things. The wiring behind the plug was tight and looked fine. Breakers were all reset.
