Ductbank
Ductbank
(OP)
I've seen multiple designs for concrete encased ductbanks. Have see a copper ground wire cast in a ductbank a couple of times, but not sure why this was done.
What is the technical reason for including a bare copper ground wire in a ductbank?
Thanks

still, i would be careful: if the duct bank is not correctly moulded, then the concrete may break and cut the cable.
