I guess AC has changed in the last 100 years.

Alternating current does not have polarity but it does have phase and a ground reference that has to be maintained. A lot of folks call it polarity. The point is that it has to be done correctly or there are a lot of potential problems depending on what you plug into it.

Be careful

Wildcatter is wrong.
My 30amp explorer plugged into a 30amp box with reversed polarity....
White to black
Black to white
Burned up my inverter. $250 later had new inverter and solar panel. And I rewired the box.
Also bought a device to check for reverse polarity.
About $30
..
.then thought..what happens if i run into this again. So I made a dogbone wired in reverse, so if I come to miswired box, my "reverse" dogbone will make it right.

Dont know alot....but I learn fast.

Do yourself a favor and clearly mark that dogbone. You will want to know what it is a year from now when you find it in your box of stuff. Worse yet is someone will borrow it.

I marked it very well with my tip of the day...
Fingernail polish

Color is much easier to see in darken spots, esp if the polish has gltter in it!

Wildcatter is sooo wrong, and is mis-understanding alternating current as it relates to tieing neutral and grounds together in the breaker box.

I'm an electrical engineer.

It IS important to have the incoming shore power wired correctly with both proper polarity and ground.

Otherwise explain it to the parents of THIS little boy who is no longer on this earth.
