NYC Emergency Panel Locations

[Raia.Alec]

Hello,

I am working on a project in NYC where an emergency generator is required by the 2014 NYCBC. Am I allowed to install panels powered by the emergency system in a non 2-hour-rated enclosure adjacent to normal power panels?

Thanks

There are a few directions that could be answered. Are these panels fed from a Article 700, 701 or 702 Gen / transfer switch?

What aspect of the NYC Building Code invokes the need for the gen? Hi-rise with an needed occupancy and load?

NEC 2008 Section 700.9(D)(2) & 700.12 has some info

Ron,

I found the answer to my question in the 2008 NEC Section 700.10.

Thank you!

Alec

I found the answer to my question in the 2008 NEC Section 700.10.

That has to be tough, because the 2008 NEC doesn't have a 700.10 , but I'm guessing you mean 700.9

NYC electrical code amendments have a .10 section.

SECTION 700.10
Section 700.10 – Add a new section 700.10 to read as follows:
700.10 Conductors for Emergency Circuits.
(A) Ampacity. See 445.13.
(B) Installation of Generator Conductors. Generator conductors shall be installed in accordance with
the requirements of Article 230.
(C) Overcurrent Devices. There shall be no limit to the number of overcurrent devices connected to
the generator terminal devices.
(D) Fire System Pumps. Fire system pumps or fire protection pumps requiring connection directly to
the emergency generator as defined in the New York City Construction Codes shall be connected as
follows:
(1) Circuits supplying fire system pumps shall be connected directly to the emergency generator with
only one overcurrent protective device which shall be rated at not less than 150 percent and not more
than 600 percent of the pump full load current.
Exception: Limited service fire pumps shall be protected by an overcurrent device selected at 150
percent of motor full load current. The next largest available device size may be used where selection
results in a non-standard device size.
(2) Where multiple generators are paralleled, the connection for the fire system pumps shall be taken
from the generator paralleling bus.
Exception: Limited service fire pumps are not required to be directly connected to the emergency
generator and may have additional overcurrent protective devices.
(3) Conductors and transformers feeding the system shall be sized at 125 percent of the pump full load current.
(4) Separate circuits shall be used for each fire system pump.
(E) Alarm Systems. All building-wide fire alarm systems shall be provided with a dedicated transfer
switch and be directly connected to the emergency generator overcurrent protective devices as follows:
(1) 208/120V systems-by a dedicated fused disconnecting means.
(2) 460/265V systems-by a dedicated fused disconnecting means with fused disconnecting means on the
secondary of the associated transformer.
