Question

In New York City, if a fire pump replacement is being taken place, does the ocpd switch on the normal side need to be tapped and maintain within the gear or does a new disconnect switch need to be provided outside of the enclosure ?

Answer 1

Replacement of a fire pump in New York requires adherence to the NEC, local building codes, and fire codes, which typically mandate that the fire pump's OCPD be 'tapped' directly from the power source. A new disconnect switch outside of the enclosure may be required based on local codes.

Step-by-step explanation:

When replacing a fire pump in New York, the requirements for electrical connections, such as the overcurrent protection device (OCPD) and disconnect switches, are guided by the National Electric Code (NEC), local building codes, and the fire codes specific to New York.

Typically, the fire pump circuitry, including the OCPD, must be 'tapped' directly from the power source to ensure reliable operation. Since requirements can vary, it's crucial to refer to the current local codes or consult with a licensed electrician or engineer. If a new disconnect switch is needed, it should be located per the NEC and must be readily accessible, which could mean being installed outside of the enclosure housing the OCPD for the fire pump.
