K-Series Heating Cable Installation Instructions
Note: Test should use at least a 500 VDC megger. Do not use a megger with an excess of 2500 VDC.
Minimum acceptable readings should be 20 megohms per circuit, regardless of length.
FOR HEATING CABLES WITH BRAID
Test from heating cable bus wires to braid.
A record should be kept of the readings taken from the time the cable is first installed on the pipe. A
history of the insulation resistance reading can be helpful in spotting moisture ingress into the electrical
system (indicated by a gradual decline in the insulation resistance) or physical damage to the heating
cable (indicated by a sharp decline in the insulation resistance). A sample record for this is shown. (See
the following page)
ELECTRICAL INSULATION RESISTANCE TEST
Electrical tests are recommended at specific points in the receipt and installation of the heating cable.
This periodical testing is designed to prevent the expenditure of wasted labor in the event of damage to
the product. Installation costs of the cable and thermal insulation are much greater that the heating
cable. Quick identification of any heating cable damage is the most economic approach to an installa-
tion. An insulation resistance test is recommended at the following point of the installation process:

UPON RECEIPT of the heating cable
 BEFORE thermal INSULATION installation
 IMMEDIATELY AFTER thermal insulation installation
 As part of a PERIODIC MAINTENANCE program
Procedure
The insulation resistance test is used to check for damage to extruded jackets. Connections for the
megger are made as shown.

PERIODIC INSPECTION RECORD
The Periodic Inspection record Form may be used in one of two ways:
1.One sheet per circuit - The results of periodic tests of a single circuit are posted in vertical columns, beginning on
the left and working toward the right. This allows easy comparison of test values for up to three test sequences on an
individual circuit.
2.One circuit per column - Test data for a single test sequence on as many as three circuits can be recorded on a
single sheet.

-7673 (toll free, U.S. / Canada) or 1-674-294-3376 (Worldwide) or [e-mail].
