    I always love the (1) conductor her ground rod clamp rule. I used to fold over the #6 Cu to go from one rod to the other but apparently that's a violation. It was still a single conductor (unbroken) but looked like two conductors because of the fold, if you know what I mean.

      Guess that depends on the inspector. I've ran the ground conductor through the clamp folded over to go from rod to rod for the 6 years I've been in the trade and so has my fellow electricians that been doing it longer than me, and never failed inspection for that.

    Just wondering has anybody besides me tried to use a 8' Ground rod in dirt to supply the power to one side of a 100 watt incandescent lamp ( other side of lamp connected to 120 VAC. Sure in the big city all concrete jungle would be a lot worst When I tried it 50 years ago the 100 watt lamp looked like a flashlight that was using two almost dead AAA batteries. My house has the best ground path. A 3/4" copper water service, steel gas pipe from underground 6" main and cast iron soil pipe.. Thing most upsetting the po!e that feeds our distribution transformer has 3 phase ( 3 wire ) 13,2KV primary but cheap lazy utility company only runs one high voltage wire to what appears to me as auto transformer. The connect the other side of primary & center tap of 120/240 volt secondary to metal case of transformer and run an aluminum wire to ground rod at bottom of pole. So every copper water service, steel gas line & cast iron soil pipe have current flowing.Even have read a 1/4 to a 1/2 amp flowing thru copper water service with the main circuit breaker off.Did run a #6 copper from service panel to street side of water water..

    Would never use a flimsy water pipe ground lamp on a ground rod. Too many of them are made of the cheapest die cast metal.
