Cable and Connection Continuity Test:
To complete a continuity test it is best to start the
installation with a power connection kit. A com-
pleted power connection kit allows for easier testing.
The bus wires and braid can be temporarily con-
nected together at the power connection end (Figure
24) and resistance can be tested at the other end as
each additional component is added to the system.
Procedure:
1. De-energize the circuit
2. Disconnect cable bus wires and ground wire
3. Temporarily connect cable bus wires and ground
wire together with a wire nut (Figure 24)
Figure 24:
4. Go to the end of the heating cable run and mea-
sure resistance using an ohm meter.
5. A resistance reading should be taken for
each bus wire to braid and then bus wire to
bus wire. Braid to A should equal Braid to
B, A to B will be slightly higher. (Figure 25)
