Re: Lightning and neutral grounding



Hi Greg:

Jon's advice is very good.  However, I would like to add one thing to what
he said about placing a "...ground rod every 16 feet (assuming 8 foot ground
rods).  That helps their effectiveness and it will prevent the inductance of
the wire from causing the problems".

You should also place an 8' ground rod at the corners of your house so the
ground wire that ties all of your grounds together is not just bent around
the corner.  Ground wires should never be bent around corners.

73,
