TEST
Test the Power Cable
WARNING
The site power must be disconnected before proceeding further.
Touching a live wire can cause serious injury or death to personnel.
1. Open circuit breaker box (9-1-0150-1 and 9-1-0150-2)/control box (9-1-0527).
2. Bring the plug end (1) of the power cable close enough to the circuit breaker box/control box (2) to
use the multimeter (3) on both ends of the cable.
NOTE
The power cable is shown disconnected from the circuit breaker for
clarity. The power cable may be checked without being disconnected
from the circuit breaker; however, the circuit breaker must be OFF to get
a true reading. If the circuit breaker is left ON, the meter may read
continuity through the pump and heater.
3. Using a multimeter (3) set to read resistance (ohms Ω), check for continuity between the circuit
breaker or terminal board/control box ends of the power cable (4) and the plug ends (1). There
should be a reading of zero (0).
4. If no continuity is present, replace the power cable.
5. Using a multimeter (3) set to read resistance (ohms Ω), check for continuity between wires at the
circuit breaker box/control box end (4) of the power cable. There should be a reading of infinity (Q).
