campground elect.

normal electric is in the 120-amp. range. at what point in amperage drop do you consider power low enough to do damage air-condishers and other elect. applinces ????

General rule of thumb from my electrical training was +/- 10%. Or 132 on the high side and 108 on the low side.

[Old-Biscuit]

The power protection devices (Progressive Industries/Surge Guard) shut down on Low Voltage (102V) and High Voltage (132V).

Now I don't mind the High Voltage trip point....but that Low Voltage trip point is ....well that is just too low for me. Below 108V I shut down A/C unit.

15K A/C unit.....2000W
120V....16.6A
108V....18.5A
102V....19.6A

No thanks!

When we lived in NJ the public power often went to about 103-104 volts in the summer on super hot days, and we never had a problem with our AC or any other appliance. We have two different energy management systems, both of them cut out about 103-104 volts, so I think that is a safe minimum. As others have said though, I truly believe the cost of the energy management "device" on my power line is worth way more than paid for it.

X2 on the surge suppressor with power management. We tend to stay at a lot of state parks with older service. Don't want to have to be constantly checking voltage. I just plug it in and let it do it's thing.

Just get a surge protector with power management on it. Then you will never have to worry about it. They are not cheap, but neither is replacing an air conditioner. Mine saved by butt. I was in Oregon when a bad electrical storm came through. Several folks in the campground had major damage to electrical components. My system shut everything down until power was at an acceptable level. No worries...... it was worth every dime I spent on it.

Anything below 108 is not good. I am currently at a seasonal site the summer. Pedestal voltage at 30amp outlet with no load is 115v which is low. On the weekends, it drops to 110. When I turned on my air conditioning, voltage under load at my wall outlet was as low as 98.
I did not like this so I bought a Hughes Autoformer to boost and regulate the voltage. With the Autoformer hooked up, I am now seeing voltage at 122 with no load at wall outlet and 117 with air conditioning running. I couldn't be more pleased. It was worth the $.

Line voltage is nominally 117 volts. You should be OK down to 8% below this. Below 107 volts I get nervous and pull the plug.

I think my system shuts down power to my coach if the input voltage drops below 110 volts or goes above 130 volts.
