Electrical Specifications
The aim of electrical cables is to be a carrier (conductor) for electrical power. The influence
of the power source on the environment, or the influence of the environment on the
power source, should be such that neither the proper functioning of the compressor nor
equipment in its environment is adversely affected. Therefore, DTC advises to use some type
of shielded cable for the mains input.
When using shielded cable, select a cable with an effective shield. A cable with an aluminum
foil will be far less effective than a specially designed conductive braid. It is best to connect
both ends of the cable shield to ground since the shield is not part of the signal path.
Alternatively, non-shielded conductors may be used if they are carried inside of a code
approved electrical metallic conduit of the flexible or rigid types.
The mains input cable should be CSA, UL, or CE approved, three-wire with a common shield
and single ground.
The cable must be rated for 90°C (194°F) minimum at the maximum
applicable current.
It is recommended that the cable be double-jacketed, i.e., teck cable
type. Refer to Table 6-4 for cable gland specifications.
