Installation Precautions . . .
• To minimize the potential for arcing and fire caused by product
damage or improper installation use ground-fault protection.
The National Electrical Code (NEC) and Canadian Electrical Code
(CEC) require ground-fault protection of equipment for each
branch circuit supplying electric heat tracing.
• Installation must comply with Thermon requirements and be
installed in accordance with the NEC, CEC, or any other applicable
national and local codes.
• Component approvals and performance ratings are based on
the use of Thermon specified parts only. User supplied power
connection fittings must be listed or certified for intended use.
• Avoid electrostatic charge. Clean only with a damp cloth.
• De-energize all power sources before opening enclosure.
• Keep ends of heating cable and kit components dry before and
during installation.
• Individuals installing these products are responsible for complying
with all applicable safety and health guidelines. Proper personal
protective equipment, or PPE, should be utilized during installation.
