electrical math - ground rods

Jan 23, 2010 30 Replies

I made a spade bit I used to aerate some really hard clay. It was about 4 ft long. A longer one could be easily made.. I drilled holes in the clay about a ft deep where grass would not grow and filled the holes with potting soil and planted grass seed.. It took about 2 or 3 years but the grass finally broke up the clay.

Coupons not usually seen else where.

Including 20% off any backhoe, and one for a free flash light.

I've lost count.

Oh, if you put the light in your pocket, turn the battery pack backwards. So that when the button get pushed some how, the batteries don't all go dead. I found mine dead in my pocket, today.

That sounds like a LOT of work. Did you use a grinder, to make a point, on the end of the rod?

Didn't need to make a point, the ground rod came with one.

Wowsers. The worst one I did took me maybe an hour or so. It was in an old fenceline between two fields. I was convinced someone must've buried an old hedge post right where I was driving the ground rod. The last half of the 10' rod went pretty slow.

the 6 i've put in in the last 3 years went in with a sledge. Two of them were in fresh backfill, and i pushed them in with my own weight.

You might want to check your current electrical code. Nebraska requires the concrete encased grounding conductors. Basically, it's 20 feet or more of 1/2" rebar. I think it's in the NEC but my book is way.............. over there.
