Turning off breaker is dangerous?

[Richpatty]

I am glad I am not the only one who thinks this is odd. DW and I stood there for several seconds wondering if we were reading it wrong…

So let’s talk about arcing for a moment. When do you see arcing (spark) with plugs? When plugging in or removing a plug? Me? Always when plugging in. Never when removing that I can recall. And this is with 120V outlets. Breaker is off for me when dealing with the RV 50A.

My procedure:

1. Open box and make sure the last person turned off all the circuits.
2. Make both the connections at the box and camper.
3. Turn on only the circuits that you are plugged into.
4.. Enjoy your stay
