I was walking a job with one of the Inspectors when we passed by the Service Equipment. This large building had 3 services, 208V for general power, 480V for the Mechanicals and 208V Emergency. It was all sequence stuff...no single main in any of them. 208V Switchboard (6 disconnects), 480V Switchboard (5 disconnects) and EM Panel (3 disconnects).

He told me that it was a lucky thing that this was an existing installation because if he were inspecting it under the new Code (based on the 1999NEC) he would knock it down for having more than 6 disconnects.

I told him that there were less than 6 disconnects for each service...and he proceeded to tell me that the Code limitation was 6 disconnects in the entire building.

I wonder what he does with Hospitals and high-rise office buildings.
