Whomever wired his EMS did it bass-ackwards. Anything reconnectable on the incoming shore power from plug to his breaker panel is reconnectable. But it is commonly it's in the umbilical cord.


you say he placed an EMS in the middle of the power cords. I'm guessing 1 shore power cord and 1 extension? That would mean that either the receptacle or the front power cord is wired wrong.

You can verify or just fix it.

Turn off power at the breaker, remove the connector, reverse the Hot and Neutral, replace connector, restore power.

Thank you to all for your responses. You have given me the info and tools to test and fix this myself. We had to evacuate this morning due to fires in Santa Rosa, CA. I will fix it when I return.

Bpbbo, If you hare some elcheapo HF volt ohm meters laying around already, won't they suffice for the testing?

The no contact tester will tell him immediately which wire is the hot wire. Using an el cheapo VM he will have to test each wire pair to determine which wire is hot. Just faster and easier. And safer since it is no contact and he can't shock himself. But, to answer your question, yes the el cheapo VM will give him that information, if he knows how to use it.

Before I switched the wires, I would want to confirm that it is, indeed, the outlet that is mis-wired. Hence my recommendation for the no contact voltage tester. If he re-wires the outlet, but it was actually the EMS that was wired backwards, he has not helped himself.

Wait a minute, Why did he place the EMS in the middle between 2 cords? Why not put it on the outlet and that would tell if the outlet is miswired wouldn't it?? Obviously he has said he had to evacuate so the friend is not currently there. The situation should be corrected though.

Since the EMS appears to be portable I assume the premade connectors are wired correct.
If EMS was hardwired version done by the RV owner I would have more concern.
Either way the pictures show the correct wire placement.

I’m sure that the wall plug is the problem as we used two different surge protectors. BTW, they are portable.Thank you everyone for your assistance.

Ken56, I believe that you’re correct. It was rushed at almost 2:00am as they were evacuated due to a fast moving fire. We were all pretty exhausted. But, that is exactly what I will do when I get back home as we all left the house yesterday. Thank you.
