    Has anybody ever experienced a shock from the shore power cord backfeeding from the bus?

    The problem you are experiencing is known as “Hot Skin” when you get shocked by touching metal on the inside and outside of your RV. Depending on the cause this condition can cause a dangerous life threatening electrical shock and should be fixed immediately.

    These electrical shocks can be caused by a reversed polarity problem in the electric receptacle that your RV is plugged into, a polarity problem in the extension cord you are using to plug in your RV or to a shorted wire somewhere in your RV’s electrical system.

    This problem can also be caused by an improper ground in the receptacle, extension cord or in the RV.

    Voltage Detector,5 In. L,90 to 1000VAC

    If you have a tester like this, wrap your hand around it and with both feet on the ground, touch it to the side of the

    coach. If it lights up, you have a problem. People have been killed by this.

    Un plug from shore power and test again.

    If you do the “hot skin Test” it would show that the problem could be something as simple as a staple through an electrical wire that is shorting it onto the body or frame of the RV or it could be an issue with the ground on your RV’s electrical system. When you get to this point it is advisable to take your RV in and have a Certified RV Technician tackle the diagnosis and repair of this problem.

    If you are getting power back through the cord, start checking at the transfer switch.

    To emphasize what John has posted he not only is correct, his warning is to be taken very seriously.

    Under no circumstances should 120 or 240 volt power coming from the generator or inverters create the description you describe unless something has failed or someone made a poorly conceived alteration to the coach.

    both ends of shore cord. We are talking about a prevost conversion? Mine was a entertainer originally and 90% of elect was run in conduit. Lots of Sticks and Staple (motor homes) were not. Don’t expect just any rv place to understand a bus conversion. Dangerous!! kill all elect sources before doing any testing!!!!
