Three Phase Motor Power Cable Voltage Rating

Anirood Hasseea

Power Supply - 3 Phase 400V

As per BS 7671, is it acceptable to use 4 cores (Br Bl Gy & Yellow) 300/500V cable be used for 3-phase motors?

What is the recommended voltage rating of power cables for three-phase motors?

Thanking you in advance.

  • Are these (cable) ratings intended to be rms or peak?

    I'd hope they were rms (like most things a.c.) - if not a lot of people are in a lot of trouble...
