Ran across this for the first time in 30 years today. Customer is wanting to upgrade service and called me out for an estimate. They told me they got a head start and had another electrician provide power to an out building. This power is taken overhead from the meter main location via a utility style cable with 2 insulated conductors and a bare neutral and no ground. This power is fed from a 2 pole breaker in the meter main. Then at the out building, it attaches to a riser mast and into another meter main style panel at this building. They own this meter not the utility. They are doing this to monitor power usage in this building. Here’s my main question/concern. This meter main panel ungrounded and the neutral is bonded via the construction of the panel. No isolation of the neutral from the body of the panel. They told me it passed city inspection but I’m skeptical and don’t want get into part of something that’s not legit. Any advice is welcome.
