Ground fault

[almcate]

Okay, probably something I should already know...but...
I use a digital meter/filter at the power post and power wouldn't pass through with an E-2 fault indicating a ground fault. Campground was soaked a couple days before (under ground water box hookup was even submerged and required bailing), so my first thought was that there wasn't usable power. Checked the 50amp circuit with an adaptor to see if it erred and the meter passed through without error.
As I really don't know what causes a ground fault and what the downsides are—did I do a really stupid thing by not moving to a different site or not?

Thanks, Al

A ground fault occurs when electricity travels outside an intended path and tries to get to the ground by the shortest route. Further it is when the "hot" wire touches the ground wire or anything else that is grounded. Could be the box, water or one of the other wires directly. It's what usually trips a fuse or circuit breaker.

If your protection device gave you a fault I would not use the electricity from that site and request another site and again plug in the surge or fault protector. I am not an electrician and don't even like working around electricity, but this is what I was told at a campground where my surge protector gave me a fault.

I may be mistaken, but i dont think your filter would detect a classical ground fault in the power box. It senses currents flowing through it to/from the trailer. It may be telling you there is no connection to the ground wire in the power box or something else. Did you try it with the trailer disconnected?
