[Amps] 2 more questions-- electrical

[Mike McCarthy, W1NR]

1. ALL GROUNDS MUST BE BONDED. This is an NEC requirement. In general I have ground rods near the 
cable entrances with the lightning suppressors attached. These are bonded via #4 solid to the master 
ground at the water meter. They also attached to 2" wide strap across the back of my operating bench.

2. All devices should have diodes protecting against reverse current flow.
