Table 3-4. P Clip sizes
Three different size ‘P’ clips allow the use of a variety of motor power cables from different
manufactures.
All motor connections must be made using a high quality braided-screen cable. Cables
using a metallised plastic bandage for an earth screen are unsuitable and in fact provide
very little screening. Care must be taken when terminating the cable screen, the screen
itself is comparatively fragile; bending it round a tight radius can seriously affect the
screening performance. The selected cable must have a temperature rating which is
adequate for the expected operating temperature of the motor case.
