Ufer Ground questions

[kwired]

You are not required by code to install a CEE, you are required to connect to qualifying metal in the footing if it is present though.

If you want a CEE and there isn't qualifying metal present then you can either add qualifying metal or the #4 copper - that is your choice though.

If you have no CEE, no qualifying building steel or qualifying water pipe, then you will need to add an electrode - rod(s) are most common thing used because of relatively low cost and simplicity in such situation.

Basic question on this same topic... (not a big forum user yet, so not sure if this is kosher vs new topic).

Anyway... I'm about to do an ufer ground for first time and leaning toward the 20' of #4 bare solid in the footing. Does this need to be attached to any of the existing rebar? Or just lay in the footing form before pour?

2nd question. If indeed there was already 20' of regular (not FRP) rebar in the footing (ie. not requiring 20' of 4 AWG), what is the recommended way to attach to the #4 solid (in my case) to that rebar? Would a direct burial bronze standard ground rod connector do?

You can use the rebar or install 20' of bare copper. For rebar just get a clamp that is listed for direct burial and for the size rebar and the conductor.

Thanks... One more. From experience, is it better to bring this wire up inside the foundation wall (perhaps sleeve it in conduit in basement so no knucklehead cuts it) OR have it come outside the foundation wall up through the soil.
