answer for bill...


i would think it almost impossible to burn up cards or starting boards. because they are all 12 volt and fed by the univolt and battery. batteries make good filters.

if a campground was on the same line as a large industrial plant such as a smelter or something with a large electric furnace, i could see problems developing.

more likely, a bad voltage regulator on the line could cause a + or - swing of 10%. still not enough to wipe out electronics. line capacitors can cause similar problems.

in the end, not to automaticly take the power company side. i would suspect the campgrounds wiring. however, power companies can and do screw up!

you call them ferrets, i call them weasels.

The best insurance......

in my opinion, is one of these - usually less than $20.

Not having one cost me a roof mounted AC.

Both low and high voltages are damaging to equipment.

Absolutely necessary if you run a generator. I found out first hand how high a voltage can go with a generator set only a bit above specs. I think it was a low voltage situation that killed the AC.

It certainly avoids speculation if a campground is delivering adequate voltage to the campsite or not.

This is one item that should be standard equipment on each and every trailer sold.

It just plugs into a wall socket and constantly monitors the AC voltage.

Surge Surpressors

The surge surpressor won't protect you from low or high voltage.
They are primarly for instantaneous short term spikes measured in thousands of a second. As john hd said they won't help on the DC side since the battery filters spikes but if you run a generator or when camping and your neighbor does something to cause a spike they could protect something on the AC side.

Radio Shack sells the meters like 87MH shows and they are your best bet for monitoring your AC for damaging low or high incoming AC.
I wouldn't leave home without one.
