Hi Stan-40, I finally got back into the 100 amp main panel I'm pulling off for my 2-pole 50-amp feebdack main.

In this 20 year old Square D box, the ground bus bar is isolated from the metal box by plastic. So I will leave my on the few neutrals that are there. I guess.

I forgot to check and see if there is only 1 neural per hole on the neutral bar, from 20 years ago when I installed it. Probably is since I have not used on the breaker slots.

I go the retaining g clip installed on the 2-pole feed-back main in the sub-panel. Thx again for that excellent tip!

Another question if your still here, is the leads and neutral to sub-panel are #6 and I ran a #8 ground wire to the ground rod outside cabin for the sub-panel.

Seems I recall two suggestions elswhere in my readings;

1) I should use as large or larger than the leads, ground wire to the ground rod,

2) I should have installed two ground rods?

I put the ground rod in on 8 or 10ft ground rod in on a 45 degree slant and was short if getting it all the way in by about 2 or 2.5 ft.

Also I installed the rod so that its actually under the house, so it may get less moisture from rain fall ergo less good grounding.

Thx for any advice.

The panel box itself cannot be a path for neutral current.

Thx for any advice. Next I figure reepticles, wiring lighting.
