My Buddy Joe M. (EC) has a job to wire a dairy barn. The concrete slab was poured before they even called him for the job, so needless to say, the equipotential plane was left out.

Having grown up on a dairy, I know first hand the importance of an EP.

Is there a fix for "retrofitting" an EP to an existing slab? Jackhammer down to the rebar? What does Joe (and I) do?
