Electrodes

[ryan_618]

I have heard from different people what, int their opinion, the "best electrode" is.

What do you feel the "best electrode" is and why?

Re: Electrodes

How about the one that allows routing of the GEC with the least amount of conductor inside the house, and with a reasonably low resistance to ground?

I'm just not so sure that an electrode with a nice low resistance but which routes all of the lightning energy through the house is such a good thing

In some of the burbs around Columbus, they do not allow a galv. ground rod. Reason: it is not UL listed.

You can not abandon it you "must" remove it.

Re: Electrodes

Mike,
The code does not require that the galvanized pipe electrode be listed. See 250.52(A)(5)(a).

I will pass this on. This will make a lot of guys happy.

Re: Electrodes

Copper clad electordes are used as they are corrosion resistant, and last much longer. A listed copper clad electrode has a thicker copper cladding. On the Olympic Penninsula near Port Angeles, electricans have found that gavl ground rods only last a few months due to galvanic corrosion. They either use copper clad or a concrete encased electrode. there are UL listed galvanized ground rods, but the copper clad would be a better choice as the copper would not create a corrosion cell due to differences in potential (corrosion).

The best electrode is a concrete encased type, as supplemental ground rods are not required, and its typically aready part of the building design.

Ground rods are best for a time and materials job.

Ground rods are best if installed by the helper. When I was an apprentice, I started work in a housing development, and I drove well over 100 rods in rocky terrain

I believe the concrete encased electrode is the better of most of our general choices.

Pierre , was that before the chipping hammer and rod adapter?
