WARNING:
Electric Shock Hazard. You MUST disconnect all power before installing or servicing
heating cable and accessories. A qualified electrician must perform installation and
servicing of heating cables and accessories. Heating cables must be grounded in
accordance with the National Electrical Code. Failure to comply with this code can
result in personal injury or property damage.

Important notes:
1) All electrical wiring including GFCI (ground fault circuit interrupters) must be installed
in compliance with the National and Local Electrical Codes by qualified person(s)
2) Article 426 of ANSI/NFPA 70 of the National Electrical Code (NEC Section 62 of
CAN/CSA-C22.1, Canadian Electrical Code, Part 1 (CEC)) Governs the installation of
these heat tracing systems
3) TRM SR-ACC-SPL/TEE (Splice and Tee Kit) is suitable for use with TRMSR heating
Cables
4) Cables should be terminated into certified junction boxes that are appropriate for the
cable termination location
5) Use 30-mA ground fault protection on each heating cable circuit for maximum
protection
6) The black heating cable core is conductive and can short. It must be properly insulated
and kept dry
7) Keep ends of heating devices and kit components dry before and during installation
work
8) The conductive layer of this heating device must have a suitable grounding/earthing
terminal
9) Do not break braid or bus wire strands when scoring the jacket or conductive core.
Damaged bus wires can overheat or short out
10) Keep bus wires separated. Bus wires will short if they touch each other
11) Replace damaged components. Components damaged by heat can short.
12) Utilize a heat gun with a low heat flame, do not use a torch with a blue flame as that
would melt/compromise the heat shrink tubing. Charring or burning the heat shrink
tubing can produce fumes that may cause irritation to skin,, eyes, nose, and throat
13) Do not heat up components of this kit (except for the heat shrink tubes)
14) When installing this cable, only use fire-resistant insulation materials such as fiberglass
wrap
15) Do not twist the cable during installation
Assembly Tools Required:
Utility knife, scissors, side cutters, needle-nose pliers, linesman pliers, channel lock
pliers, crimping tool, flathead screwdriver, heat gun, measuring tape/ruler.

Controls and GFI:
TRM SR can function safely without the use of controls, but it is strongly recommended to utilize thermostats or controllers
to maximize the efficiency of the cables while simultaneously minimizing electrical costs.
For further information or for design assistance with controls and/or sensors that work in concert with our SR cable, please
call TRM directly
Circuit protection depends on the breaker size being used and the start-up temperature. NEC 1999 requires the use of
ground fault protection breakers for heating cable. The above chart shows the maximum circuit length for a given breaker
rating. To determine the number of circuits required for each pipe, divide the total cable (circuit) length by the maximum
circuit length found in the chart. Round up to the next higher number.

SR Cable Construction
Standard
A. Buss Wires
Twin 16 AWG copper buss
wires provide good current
capability
B. Matrix
A semi-conductive polymer
core whose electrical
resistance varies with
temperature. When process
temperature drops, the core’s
heat output increases;
conversely, as process
temperature rises, heat
output decreases
A B C D
C. Tinned Copper Braid
The braid covering the jacket
provides an effective ground
path and mechanical
Protection
D. Jacket
The flame retardant insulation
jacket is a polyolefin material with
excellent water resistance. It also resists
certain mildly corrosive Chemicals
Description
Thermal Resources Management brand SR
cable is ideal for keeping metal and plastic
pipes warm in commercial construction,
institutional buildings and some industrial freeze
protection applications. TRM SR cable is
constructed of a self-regulating polymer core
that varies its output along its entire length,
saving energy and eliminating hot spots along
the pipe. Parallel construction makes it easier to
install than zone or series types of cable since it
can be cut to length at any point on the pipe. It
can be single overlapped without overheating
the cable.
