Why Do I Get Shocked When I Touch My Trailer Frame?

Trailer frames can provide a hidden shock if electrical connections within a campsite, or within the trailer itself, are not properly maintained or repaired. The shock could be small or large, and possibly dangerous.


Function

Improperly wired electricity can charge the frame of a trailer.

Improperly wired electrical wiring, from reversed polarity to missing grounds, can charge the metal framing of a trailer.  It will not discharge because the rubber tires act as an insulator to ground.

How the charge dissipates is through the touch of a person's hand, creating a complete circuit to ground for the charged frame, entering the hand and exiting through the feet. 


Helpful Tips

Be sure to plug in a trailer to a well-maintained electrical outlet that has a snug fit on the plug.  If repairing a personal power cord, note the polarity and where wiring is to be matched so wires are not reversed, causing a charge to build on the metal trailer framing.


Warning

A shock can possibly cause heart attack or death.  Verify any wiring before applying power.
