Strange electrical happening

[urlbee51]

I have a Progressive EMS 30amp and always use it.

One outlet causes the post 30 breaker to shut off. This is with the Progressive attached.
No other outlet does this.
We are drawing about 18-19 amps according to the 30Amp Progressive.

Only this one outlet causes this.
It has happens twice at the same park but different places.

This same thing does not happen at my house when plugged into my new 30Amp service.

Any ideas?
Thank you.

Welcome to the forum.

What do you mean one outlet causes this?

Only the outlet under the dining table causes this.
I can plug in anywhere else and no problems.

What are you plugging in?

Which 30 amp breaker is tripping?

I am plugging in an iPhone charger.
Same issue whether a power strip or directly with a device.
In this case a iPhone power charger.
This is the only outlet that causes this.
The dealer said there was nothing wrong but I don’t believe they looked at it.

The post 30 amp.
The breakers in the TT don’t trip.
Just at the post where I have the PTX 30 plugged in.

What else is on that outlet's circuit, and like already asked, what are you plugging in?

If it's an old RV park, could be a breaker that is going bad, they dont last forever and tripping well below the setpoint is a good indication it is starting to fail. Of course overloading the circuit is also cause for the breaker to trip. If you never see more than 19A on your EMS, you probably arent overloading the breaker.

Just plugging in an iPhone charger or a power strip.
Last time an iPhone charger.

This happened at 2 different spots in same park but not at home.

Go get an outlet tester. Watch the LED indicators when putting the slide in and out. I'd wager the problem with then present itself.
