I have enjoyed and benefited from the work Mike Sokol has put into his website. Considering the alarming percentage of campers that experience electric shock at some point - I highly recommend his site to everyone for the sake of your families safety....(or to help that newbie-neighbor
)
Here's the link if you haven't saved it or visited already.

I may be one of the few - but I carry a small voltmeter and like to test any power source I'm plugging my rig into. I don't want my vacation over before it gets started. And because I'm absentminded...

Following (and hopefully attached) is a 50A 30A 15A wiring / test card template I made up in wallet size and larger (for storage in the TT)....
Be safe and smart with electric.
