The air conditioner's spec is 115 volts +/- 10%, or 103.5 to 126.5 volts. That's at the air conditioner when it's running. If the EMS shows 106 or more when the air conditioner is running you should be within spec. If the RV's wiring drops more than 2 volts between the EMS and air conditioner, that would be a different problem.

Low voltage can burn up your shore cord plug too.

I have one of these RV120VAC VOLTMETER (AMAZON) installed in one of my AC receptacles to alow me to watch the AC VOLTAGE all the time... This has the GREEN SCALE on it for easy viewing...

good post

i have a digital readout version of this. at home when i cool our TT with 15kbtu ac plugged into 20 amp 110 outlet at garage i turn off our outside kitchen mini fridge and switch rv fridge to propane.

when ac compressor is kicking in my voltage usually goes down to 110 or so even in hottest part of day.

That green scale is off quite a bit since anything above 105 volts is acceptable. I suggest buying a digital voltmeter.

I have one like RoyB posted, but it shows the voltage to be a little less than actual. I bought a new digital one, that is much more accurate, and shows the same as my digital multi-meter.

Good point on the GREEN SAFE marking alittle above what the spec is. I still like seeing he GREEN marking zone being visible...

I also have the digital version here on my social media console here which is probably more accurate than the analog scale version... It is reading 115VAC this morning... Usually around the 120VAC reading...

Looks like this from AMAZON

The point here was getting a readout inside the trailer to observe your AC VOLTAGE on a regular basis... Even if it is a VOM with the test leads pushed into the AC SOCKET and meter hanging on a nail haha...

I was told by my converter (Liberty Coach) to not run below 110v to stay on the safe side. The coach is in a large storage garage and I can check everything from my iphone. This morning I was showing 111v on leg #1 with one air running. I also have two refrigerators (small one in basement) and the battery charger will charge as needed.

Apparently when I checked, the battery charger was on and then turned off and the volts changed to 114v. So, I turned off the front air and turned on the bedroom air as it's on leg #2. It was showing 116v on leg two with the air running and leg one went to 119v.

I've run it occasionally with voltage reading as low as 100. Not recommended I know. But no problems yet. Crossing fingers.

I have the same one. Quick and easy to see the voltage, don't even need my glasses on. [emoticon]
