Pending Code Change Item for 2011
As noted in the NEC Committee Report on
Proposals, 2010 Annual Revision Cycle, Code-Making Panel 13 has
voted to accept a Code change submitted by Thomas Guida, TJG Services,
Inc. (Log #2915 NEC-P13). The recommendation calls for revising the
of Sec. 708.14(1), (2), (5), (7) and (8) as follows:
"(1) All cables for fire alarm, security, s
systems and emergency communications wires
shall be use shielded twisted pair s
"(2) Shields of cables for fire alarm, security, signal systems
and emergency communications
signal and communication wires
shall be continuous."
"(5) Conductors for all control circuits rated above 50V shall be
installed with wire rated not less than 600V."
RiserAll cables for fire alarm, security, signal
systems and emergency communications communication cables
shall be riser-rated and shall be 2-hour fire resistive cable
or a listed 2-hour electrical circuit protective system."
"(8) Control, monitoring, and power wiring to HVAC systems shall be
2-hour fire-resistive cable or a listed 2-hour electrical
As noted in the submitter's substantiation summary, these changes
meant to clarify which cable types require shielded twisted pairs, and
which require riser ratings. Two hour fire resistive cable in conduit
required by 708.10(C)(1) is an electrical circuit protective system.
