Please see attached sketch it shows service conductor call it A tapped from the line side of the main switchboard six main service disconnects.
The service conductor A then goes into trough where it is connected to conductor B which feed jockey pump controller service rated and the service conductor A is connected to conductor C which feed fire pump controller service rated.
The jockey pump controller and the fire pump controller service rated are both remote from the main service switchboard and room.
I have the following questions:
1. Does not the jockey pump controller need to be grouped with the main service switchboard and Not be remote? I do not see any exception in NEC 2017 section 230.72 for jockey pump service disco to be grouped.
2. Is jockey pump considered water pump? Not sure if 230.72(A) exception regarding water pump apply or not
3. I know you can have additional service disco for fire pump more than six however in the diagram below the jockey pump controller service disconnect would make it seventh main service disconnect when counted with main service switchboard. I dont see any exception for jockey pump to have 7th service disco 230.70 or 230.70? Would jockey pump service disco count as 7th service disco or if exception which section is it?
