- Maintain - and update - installation and
maintenance records. Complete documentation will allow you to verify completed
system tests, original electrical values and performance changes.
- Check heat tracing components. Damaged components
can result in water ingress, corrosion, or the loosening of electrical
- Check your insulation. Insulation plays a critical
role in the overall heat tracing system. Also, perform an insulation resistance
test on all heat tracing circuits.
- Check your power distribution panel and secondary
wire and conduit. Visually inspect the conduit distribution system for openings
in the conduit, damaged or missing components, or low-point drains.
- Test all ground-fault breakers according to the
- Check your thermostat or control system. They
allow you to run automatic tests and capture alarm and fault information, which
is useful if troubleshooting your heat tracing system becomes necessary.
- Energize each heat trace circuit to ensure that no
short circuits or ground faults exist and that RTDs are functioning properly.
- Stock critical spare components and cable. If your
system still fails after all your checks, stocking spare components and cable
will allow for timely repairs or replacements.
- Don’t wait until winter to check your electric heat tracing system! Or if you have, don’t skip maintenance checks just because you “don’t have the time now.”
