Two overcurrent protection protecting one device?
Two overcurrent protection protecting one device?
(OP)
Hi Guys,
I am having an electrical upgrade for a building in New York where I have a meter bank and pullout fused switches protecting each apartment panel, I was asked to provide main circuit breaker panels in each apartment for maintenance issues, is this allowed by code to have two overcurrent protection devices in a row protecting one device(panel)?
Also since these are big apartments we are providing 3 phase 200A service for each apartment, the meter bank or 'meters set' for that came out that the pullout fused switches had to be at 7'-4" high, I was told that this is high, but I can't see anywhere in the code that indicates a height limit for them?
Thank you all for the input.

As for height of switches and breakers, look up NEC 110.1 and 404.8. You should also look up any amendments in NYCEC.

Cable is protected by the meter pullout fused switch in the electric room.
