Okay, let's break down the requirements for fire pump feeder and service conductors in NYC, according to NEC 2008, and specifically address the conductors inside the fire pump service equipment.

Understanding the Code Requirements (NEC 2008 & NYC Amendments) NEC 2008, 695.6(A) and (B)

These sections deal with the physical protection of fire pump supply conductors. They generally require that the feeders be protected from fire damage, often by methods like: Concrete encasement (2 inches minimum). Burial outside the building. Raceways encased in concrete. Fire-rated cable or raceway systems. Fire-rated room or shaft.

NYC Amendments (Important!)

NYC typically has significant amendments to the NEC, and these often add more stringent requirements, especially regarding fire protection. You MUST consult the NYC Electrical Code, which is based on the NEC, but with NYC-specific modifications. Look specifically for any amendments to Article 695 or related articles. These are often found in the NYC Building Code as well.

Answering Your Question: Conductors Inside the Equipment

The key is to understand the intent of the code: to ensure that a fire will not interrupt the power supply to the fire pump before it can do its job. General Rule: No, the conductors inside the listed fire pump controller or service disconnect do NOT typically need to be individually fire-rated or concrete-encased. Why?1. Equipment Listing

The fire pump controller and service disconnect switch are listed pieces of equipment. Underwriters Laboratories (UL) or another recognized testing laboratory has evaluated the entire assembly (including the internal wiring) for its ability to function under specified conditions. The listing includes standards for internal components.2.

Point of Disconnect

The protection requirements (concrete, fire-rated cable, etc.) are focused on the conductors feeding the equipment from the service entrance. The idea is to protect the FEEDER. Once the feeder conductors terminate inside the listed equipment, you're relying on the integrity of the listed enclosure and its internal components.3.

Practicality

It would be impossible to encase every inch of wiring within a complex piece of equipment like a fire pump controller in concrete.

Important Considerations & Potential Exceptions


Local Amendments

Double-check the NYC Electrical Code and Building Code! It's possible, though less likely, that NYC has a special amendment requiring additional protection even inside the equipment. If so, it would be explicitly stated.2.

Equipment Manufacturer's Instructions

Always follow the manufacturer's installation instructions for the fire pump controller and service disconnect. They may have specific requirements or limitations regarding the installation.3.

Service Equipment Enclosure

The enclosure of the fire pump service disconnect switch might need to meet certain requirements, such as being NEMA 3R rated if exposed to weather, or having a specific fire rating for its location.

Code Sections to Review



NEC 2008, 695.6 (A) & (B)

Physical protection of feeders.

NEC 2008, Article 110

General requirements for electrical installations (workmanship, listed equipment, etc.).

NYC Electrical Code and Building Code

Search for amendments related to fire pumps, Article 695, and service equipment.

UL Standards (or other listing agency standards) for Fire Pump Controllers and Service Entrance Equipment

These define the testing and performance requirements that the equipment must meet to be listed.

Recommended Action Steps


Consult the NYC Electrical Code and Building Code

This is the most critical step. Look for amendments to NEC Article 695 and sections on fire protection. Contact the NYC Department of Buildings if you need clarification.2.

Review the Fire Pump Controller and Service Disconnect Specifications

Carefully examine the specifications for the equipment you're using. Pay attention to the manufacturer's installation instructions.3.

Talk to the Authority Having Jurisdiction (AHJ)

The local electrical inspector or fire marshal is the final authority. Discuss your proposed installation with them before you start the work to ensure that it will be compliant. Get their approval in writing if possible.

In summary, while you need to protect the feeders to the fire pump service equipment with the required fire-rated methods, the conductors inside the listed equipment are generally covered by the equipment's listing and do not require individual fireproofing unless specifically mandated by the NYC Electrical Code or the equipment manufacturer. Remember that local amendments are crucial in NYC. Always prioritize local code requirements and the AHJ's interpretation. Flag for review
