That's tough on electronics. The lower the voltage, the higher the current draw... Things are cooking somewhere!

Hot summertime, A/Cs blasting, older park 92V. EMS had disconnected.
Quiz: 30A pedestal, 160V, hint open neutral - Why? Of course this happened at 10 PM.

Years ago I measured my A/C, lower voltage resulted in lower amps because the motor produced less HP. Several others reported the same.
Not suggesting low voltage is OK...![[emoticon]](http://www.coastresorts.com/sharedcontent/cfb/images/biggrin.gif "biggrin")

102vac but it shut down my EMS so I couldn’t read lower.

My lowest is just below 100. That is when the AC fan is set to auto, and both the fan and compressor start up nearly the same time.
However this low voltage, is just a second or two, so you'd have to be watching the meter closely. It quickly returns to 112-116, depending on other electronics running.
I don't feel this quick spike is hurting anything, and is normal.
What are others thoughts, as to very brief low voltage, on AC startup?

Only inductive loads are bothered.
Which is why I invested in an autoformer. Lowest I've seen with the autoformer is 108. I have it set to cut in at about 113.

92 is seriously LOW!
Interesting on the measurements. I've not seen that happening--but to be fair I was not looking either. I merely suffered without roof air.

I think that there will be spikes. Some folks on other threads have mentioned as low as 65 volts (iirc). That would concern me. And other campers on the same loop would have the spike/brown out happen to their RV's too.
