DESIgN PROCEDURE
The following procedure can be used to select a heating cable
system for your application. However, Easy Heat can also pro-
vide design assistance and will recommend appropriate cable,
controls and accessories. Call Easy Heat for further information.
To determine the heat loss that must be replaced by the heating
cable, the following should be determined:
• T
F
Fluid temperature to be maintained
• T
A
minimum ambient temperature
• Size and material of pipe to be heated
• Thermal insulation – type and thickness
• Pipe supports and valves, etc.

The use of ground fault protection
equipment for heating cable applica-
tions is required by NEC and CSA CEC.
tSr cable with polyolefin overjacket
(suffix ‘J’) may also use Sr trace Kits
in nonhazardous applications.
