SECTION 695.6
Section 695.6 ? Revise to read as follows:
695.6 Power Wiring. Power circuits and wiring methods shall comply with the requirements in
695.6(A) through (E), and as permitted in 230.90(A), Exception 4; 230.94, Exception 4; 230.208;
240.4(A); 240.13 and 430.31.
(A) Supply Conductors. Fire pump and limited service fire pump supply conductors shall be physically
routed outside a building(s) and shall be installed as service entrance conductors. Where supply
conductors cannot be physically routed outside buildings, routing through buildings is permitted where
installed in accordance with Section 230.6(1), (2), (4) or (5).
Exception: The supply conductors located in the electrical service room and generator room where they
originate and in the fire pump room shall not be required to have the minimum 2-hour fire separation or
fire resistive rating.
(B) Circuit Conductors.
(1) Fire Pumps. Fire pump supply conductors, including emergency supply conductors where
emergency power is provided, on the load side of the final disconnecting means and overcurrent device
shall be kept entirely independent of all other wiring. They shall supply only loads that are directly
associated with the fire pump system, and shall be protected to resist potential damage by fire, structural
failure, or operational damage. They shall be permitted to be routed through a building(s) using one of
the following methods:
(1) Encased in a minimum of 50mm (2 in.) concrete using rigid metal conduit (steel RMC),
intermediate metal conduit, electrical metallic tubing or schedule 80 non-metallic conduit.
(2) Rigid metal conduit (steel RMC) within an enclosed construction dedicated to the fire pump
circuit(s) having a minimum of a 2-hour fire resistance rating.
(3) A listed electrical circuit protective system with a minimum 2-hour fire resistance rating. The
installation shall comply with any restrictions provided in the listing of the electrical circuit
protective system.
Exception: The supply conductors located in the electrical service room and generator room where they
originate and in the fire pump room shall not be required to have the minimum 2-hour fire separation or
fire resistive rating.
(2) Limited Service Fire Pumps. Limited service fire pump supply conductors shall be installed in rigid
metal conduit (steel RMC) or intermediate metal conduit (steel IMC).
Exception: Where there are multiple sources of supply with means of automatic transfer from one
source to the other, electrical metallic tubing (EMT) shall also be permitted.
