Electrial Question

Another alternative is to use an isolation transformer. It will boost voltage so the incoming power is usable.

Of course there is - unplug immediately and remain unplugged until the situation is resolved. In the meantime, invest in "protection" so regardless of what transpires in the future it will shut down power to the trailer and thereby protect it's electrical system if it senses anything wrong with the incoming source power. It's also clear proof to any campground host that is in denial that there really is an issue with the park's power system.

Your campground host is in denial. He either has a wiring problem with his 'new' system, or it is simply over-loaded by all the campers plugged into the system. Not much you can do about it...and you're probably doing the right thing by not using your A/C if the voltage is under 108VAC on your meter.

I use one of these RV AC VOLTMETERs plugged into a handy 120VAC receptacle so I can get a good glance at the AC VOLTAGE LEVELS. The SAFE ZONE is printed in GREEN.



If the METER is showing just under the GREEN ZONE I will use my MULTIMETER to measure the AC VOLTAGE to get an more correct reading.

This is a good chart to use to make measurements using a MULTIMETER at the camp ground pedestals for the 50A and the 30A readings.

50AMPS


30AMPS/20A/15A


Another good test is use one of those inexpensive CIRCUIT TESTERS (LOWES-WALMART-AMAZON).. The problem with these is they only plug into the 120VAC 15A/20A RECEPTACLES so if you want to the measyre the 30A or 50A side of the pedestal you will have to to use the standard RV 50A and 30A ADAPTERS.


Burning up your appliances can get expensive...

Yours is a classic case where you should absolutely invest in a surge protector such as a Progressive Industries EMS-PT30C which will also protect your trailer's electrical system from low / high voltage and a host of potential wiring errors. Sorry, but I can't even remotely imagine plugging into an electrical source of any kind that's showing even the slightest indication that it may not be delivering power correctly without using some sort of "protection", as doing otherwise could cost literally $$$$ thousands in repairs. :E :M

I think the red zone on the meter you mention starts about 110. If it would stay at that point, when running your electric appliances, and AC, you would likely be okay.

However, if it is in the red, with none of your appliances running, it will likely drop even more. I would not use any appliances on electric, when the meter drops to 106.

I would think the camp owner would know that this problem needs to be corrected!

One other thing, if your battery is charging at full rate, it will cause the power to be lower, until battery is charged.

What is the actual voltage?
