Question for those of you who use a SurgeGuard produced by TRC. I have a SurgeGuard by TRC, model number 34560 hard wired into the RV where the 50 AMP cord connects. Am now in Gatlinburg TN at a campground where the power voltage in this community runs high, 129v to 132.4v as observed with volt meter at the pedestal. The trip range on the SurgeGuard is 102v to 132v, so guess what, every time it goes above 132 it trip outs. It’s a pain in the b---. Questions, have any of you run into this problem before and if so what have you done? Does any one know if this model's trip range can be adjusted slightly higher?
Thanks for suggestions.

I had a 30 amp model before that had a key switch that you could turn off the low/high voltage shut down but still have surge protection. My current 50 amp does not. Maybe you could find one that does.

Get a plug in heater and run it outside continuously to draw down the voltage. Either plug it into the pedistal outlet or your outside outlet.

High voltage at the pedestal needs to be corrected by the CG or you move to another site or another CG.
When the voltage is high on one leg is the other leg correspondingly low? If so then that indicates a problem on the 50A neutral. A 50A neutral problem can cause either leg to have very high voltage.
You have not posted anything to suggest a problem with the SG. In fact it's protecting the rig as designed.
But a question does need to be asked about your voltmeter. Is is reasonably accurate and designed to measure RMS voltage? Not all voltmeters give accurate results. If you are not sure have it checked or compared to a good quality voltmeter like a Fluke.

I had a similar problem with my home 50 circuit. Turned out to be a loose connection on one of the line legs. I would suspect that one leg of parks service is bad.

It sounds to me like the SurgeGuard is doing its job of protecting you. The problem from the electric source should be corrected, not your protection.

I thought there may be some easy answers to this problem but was not sure.
Here's a little more information that may help with the original questions.
A week ago Friday, Sept. 26th we pulled into a campground seven miles up the road from where we are now. Problem of tripping SG started late Friday evening. Spoke with campground manager the next day and he did not have any answers. So we moved to a different campground on Saturday, Sept. 27th. which is where we are now. Got setup and no SG problems all weekend or during the week until Friday, Oct. 3rd. late afternoon. Problem persisted Friday into Saturday all day and night. Today is Sunday and no problem.
At both campsites I was/am setup on a 30 amp circuit.
I have a really good meter so I don't think that is a problem. No one else in campground has a hard wired SG on there input power lines so no one else experiencing the problem.
Gatlinburg TN is a big tourist area and things really come alive on Friday evenings. Wondering if with all the electrical demand in the area if the Electric Co. is kicking up the power output?
Agree that the SG is doing what it is intended for but if I could make an adjustment of 1v on the high side of the range, I probably would not have this problem.
Hope you guys can shed some light on this? Maybe the area has a lot of gremlins and Friday nights is when they come out especially now with Halloween so close, LOL!
Thanks for all your thoughts and suggestions.

OK, good meter and 30A circuit. High voltage at the pedestal is a CG problem for whatever reason. The CG should call the power company for an answer. It could be a power company problem or a CG problem but that doesn't solve your short term problem.
I read the SG specs and they didn't mention any voltage adjustment. But the Progressive Industries HW50C unit had better specs, a remove display (includes a bypass protection switch), field replaceable parts, no voltage adjustment and lower price. Not hard to guess which one I bought!

You may think it's a PITA (Pain in the Anatomy) resetting all the time.. but Consider the pain of replacing things damaged by the high voltage
That's a PITW (Pain in the WALLET) and trust me, those hurt more!!!!

There is a brute force solution that I used in Mexico, which is to use a long extension cord before the surge protector to drop a small amount of voltage. My problem was that campground voltage was 125 volts when a big rig was parked next to me - when they would disconnect and leave in the morning the voltage would go to 133 volts and kick out my surge protector- sure upset the automatic coffee maker lol. The 75 foot extension cord dropped the voltage to about 120 when a rig was present to 130 when not. As I said brute strength way to solve the campgrounds problem.
