The TRC surge guard has a key switch so that you may bypass the system. No need to physically remove it from the system.

Turns out the keys that the installing dealer gave me won't turn that switch!

The fix to my similar problem was tightening the connections inside the transfer switch.

Unplug from the power pole first !!!!

I'm betting Dean is right. Open the xfer switch (this assumes you know your way around 120V electricity and understand proper safety precautions; otherwise get somebody who does), and check both incoming & outgoing connections. Most mfgr's installed the cord-end wires as they came pre-stripped from the cord factory into the xfer switch terminal sockets & tightened down. The strip length on factory cords frequently comes too short for those xfer switch connections, so OEM install may have pinched insulation in the termination along w/copper. Over time you may have developed a hot spot and partially fried the termination. I pulled mine apart when new and found this on half of the terminations, the installer didn't do proper stripping. Could also be one or more terminal screws are simply loose from expansion/contraction.

Could also be the electro-mechanical xfer switch is dying. We all get old, eventually.
You could request a different space on a different transformer in same park; if you get same result, odds increase that its you and not park power (i.e. not a perfect check, just another data point as park service may be the fault source; if you move to another park and nobody else is affected but you still have this problem, then its you).

I did the same thing one time except...
I used wire nuts to connect the 50A shore power plug to the house and went to big box hdwre store n bought a dryer recpt n wired it to the generator wires
Then all I had to do was plug to shore power or plug to generator and bypassed xfer switch till I got home
Worked great!!!
Just sayin...

Hmmm, here's a lesson in life: why not assume equipment is working properly, and spend more effort proving the external stuff is working properly?

Yesterday, I phoned TRC to get a key that would work in my Surge Guard. Very nice man in tech support talked to me about the problem I was having with my equipment, and when he learned I had found a steady voltage at the cg power post of 128 volts, he said "that's so high, it wouldn't take much to properly trip the Surge Guard."

After the call, I checked voltage, and it was now 122. And I realized there had been NO cutouts by my equipment since the evening before. So I waited and watched. Continued to check voltage...never higher than 125, and usually 122.

No more cutouts all day!

Awakened at 1am today by transfer switch banging open. Grabbed by meter and my pants, and went to the post: 128 volts on one leg, other was 125.

Got my chair and sat beside the Surge Guard with volt meter on the line in: one leg of the 50 amp was consistently 128+ and the other was 122-125.

Watched the one leg slowly increase to 129, and slowly increase more....when it flickered above 129.9 the Surge Guard cut out & transfer switch banged open.

Textbook operation of my equipment!

So it's the cg's power post (and I experienced this at a different site, so it's widespread).

I've also learned to check both legs of the 50 amp, because it only takes one leg to trip the Surge Guard.

Thank You each and every one for your very kind consideration of my post and your offers of assistance!

I'll go back to sleep now, literally and metaphorically.

WOW!, Doug. Glad you found the problem. I'm visualizing you sitting there in your "jammies", probably wearing a heavy coat and fiddling with a multi-meter while the neighbors are looking out the window thinking..."What the HE$# is THAT guy doing out there?" Now, if you had an adult beverage with you, they'd be even MORE confused.

I've had electrical issues with CG's before and they really ARE hard to resolve. The CG owner typically can't believe it's HIS fault, so unless you can prove it to him while he's standing there, you won't get it resolved. Makes you wonder what happens to campers before and after you.
