Heating cable types
This component is an electrical device that
must be installed correctly to ensure proper
operation and to prevent shock or fire. Read
these important warnings and carefully
follow all of the installation instructions.
• To minimize the danger of fire from
sustained electrical arcing if the heating
cable is damaged or improperly installed,
and to comply with the requirements of
nVent, agency certifications, and national
electrical codes, ground-fault equipment
protection must be used. Arcing may
not be stopped by conventional circuit
breakers.
• Component approvals and performance
are based on the use of nVent-specified
parts only. Do not use substitute parts or
vinyl electrical tape.
• The black heating cable core and fibers
are conductive and can short. They must
be properly insulated and kept dry.
• Damaged bus wires can overheat or
short. Do not break bus wire strands when
scoring the jacket or core.
• Keep components and heating cable ends
dry before and during installation.
• Use only fire-resistant insulation
materials, such as fiberglass wrap and
flame-retardant foam.
HEALTH HAZARD: Prolonged or repeated
contact with the sealant in the core sealer
may cause skin irritation. Wash hands
thoroughly. Overheating or burning the
sealant will produce fumes that may cause
polymer fume fever. Avoid contamination of
cigarettes or tobacco. Consult MSDS VEN
0058 for further information.
