GEC suport

[Ponchik]

What is the requirement for supporting GEC in crawl space? say #4 solid.

Take a look here:

250.64 Grounding Electrode Conductor Installation.
(B) Securing and Protection Against Physical Damage. Where exposed, a grounding electrode conductor or its enclosure shall be securely fastened to the surface on which it is carried. A 4 AWG or larger copper or aluminum grounding electrode conductor shall be protected where exposed to physical damage. A 6 AWG grounding electrode conductor that is free from exposure to physical damage shall be permitted to be run along the surface of the building construction without metal covering or protection where it is securely fastened to the construction; otherwise, it shall be in rigid metal conduit, intermediate metal conduit, rigid nonmetallic conduit, electrical metallic tubing, or cable armor. Grounding electrode conductors smaller than 6 AWG shall be in rigid metal conduit, intermediate metal conduit, rigid nonmetallic conduit, electrical metallic tubing, or cable armor.

I have seen that but it didn't give me an exact number as far as the distance between supports.

i guess it is a judgment call how far apart the supports need to be and how neat job wants to do.

Thank you.

You're correct it doesn't specifically say how far apart you need the supports spaced. IMO 3'-4' would be sufficient to keep it against the surface.

I would just support it as I do nm cable.
