I just read some of the posts about concrete encased electrodes. I have a similar question.
A customer is ordering a steel building, sort of a Quonset hut type. Will have a concrete slab. I have not been involved in wiring this type of building before. Would I need a 20 foot ground rod to bond to the rebar/grid wire? Would I be good to lay 20 feet of #4 bare cu & bond to rebar/grid wire with split bolts or would I have to cadweld? I plan to also drive 2 ground rods as usual and ground the meter base from there.
Will I need bonding jumpers at corners to bond metal base plates? Any jumpers for the metal siding and roof?
