When I mentioned using aluminum diamond plate for a shower pan to our electrical instructor at the technology center... I asked about grounding the pan, and he said in my situation (stick & air nailed storage building), a ground lug should be tig welded to the pan and bonded to earth ground.
When I read that article last night about "hot skin" on a bus, it really made me wonder about generator electricity! I know if my bus electrical is proper, it'll pick up the earth ground from the shore electrical pole at an RV campground, but what about generated electricity and rubber bus tires?
Sure would hate to pound in a ground spike at every campsite and clamp bus to ground.... But, I would if I felt I needed to!
What about the anti-static strip I've seen on some vehicles?
I guess I could toss out my Danforth boat anchor on steel chain and get a good hold!
I'm also interested in this topic!
Here's some previous discussion
