We are at a campground that only has 30 amp. I tries one of those Chester adapters that have a 30 amp and 15 amp going into a 50 amp. Every time I plugged the 15 amp in it blew the surge protector on the outlet, Any ideas?

Hi,

It depends on how the pedestal is wired. It won't work on a GFCI outlet, for example.

Some campground pedestals have the load side of the 30A breaker connected to the 30A receptacle as well as the line side of the 15A breaker. So a cheater cord won't gain you anything. All the load goes through the 30A breaker anyway.

Yeah. No matter the wires or the plug, you can't draw 50 amps off a 15 amp circuit. Ain't gonna happen.

The cheater does not advertise 50 amps. It simply connects 1 of your legs to the 30 amp and the second leg to a 15 or 20 amp. Obviously not 50/50amp legs as normal, but better than 15/15 off a dog bone. Enough to run 2 air conditioners IME.

Downfall is it trips ANY gfci protected outlet, which is at almost every campsite pedestal. Which is the OPs problem.

The cheaters don't work, especially if there is a GFCI. An energy management system will also fault.

If you are just trying to connect to a 30 amp circuit use a simple 50 amp to 30 amp adapter.
If your trying to take advantage of the additional 20 amp outlet I suggest:
RV safe power transfer switch. Works with GFI outlets

The RVsafepower switch allows me to use both A/C's on 30 amp sites.

Their web site is malfunctioning. But from what I can see I wouldn't dream of using one of those. 2 AC's drawing 10-15A each can run on 30A, assuming you can get them started.

If a pedestal has only 30A of 120V then nothing can get more power. You can cheat the safety margins, overheat the wires, and risk damaging the entire campground system.

There are no techno devices to get around the laws of physics.
