My thoughts too. Power is power, it can all flux. I'm putting mine in line after the transfer switch to protect from both shore and gen power surges.

I have used both and installed a thirty amp unit into a class C and a 50 amp in a fifth wheel. I still have my external one, but check the power on the post using a volt meter. I also have a non contact voltage tester to make sure that the post is not hot or have a floating ground.

The only thing the Non contact tester will tell you is there is some sort of voltage present. It can tell you nothing about the ground or neutral or which wire the voltage is on. Be safe.

If your rig is hot, it will tell you so. It should be grounded. If the post is hot, it will tell you so. It should be grounded. Then a meter can tell you the exact voltage. Why should a grounded post or RV be hot. Well a missing ground to the main power pole. It has killed people thinking that their rig was grounded. Just an open ground in a park section can do this. A kid died two years ago do to a faulty ground in a park section's power wiring. What you do not know can kill you. It doesn't happen very often, but it does happen.



I have a very sensitive non contact tester. I have used it to follow the wiring in the walls to know their exact routing. It is a quick and useful tool. Not and end all be all tool.

I have an external unit. After seeing a photo of one installed in the coach that took a hit and burnt up part of the coach... I agree, the further away the better. I also camp in some small county parks and like being able to test the pedestal before hooking up. Whatever kind you choose, I too think they should be mandatory.

I have a friend that had, they think, converter failed and burned his coach and house down. The insurance agent came to his one wall remaining house and ask where the rig was. He showed him molten metal a few wires, molten rims, and a lot of carbon black. He and his wife were lucky that they were up early going on their honeymoon to Africa. They did not have time to get their pack suitcases sitting by the front door. Flames were shooting through before he could turn around and grab them as he stepped out. He had his new rig two weeks. Went out with it for a weekend. It can happen to any electronic device. Famous are main power connectors and transfer switches along with power reels and breaker boxes. You got to open them up and make sure the connections are tight and do not loosen up. A lighting strike destroying a EMI protection device is not unheard of. Our power plugs in out home will do the same thing!
