“Domestic” Cable for Motor Applications

Disconnection times referring to the undersized CPC in T +E.
Vibration issues in terminations of the final length Rotary to Motor control are the answers picked up from the responses so far.
A J - disconnect times
Marvo - undersized CPC
Everyone else - vibration issue

With regards to Vibration issues, I was one of those who supported that, but what about MICC that had solid core conductors, although Electricians sometimeput a loop in the cable to counter act vibration.

No problem with disconnection times and the earths all seem suitably sized. 6mm twin and earth is the largest in place. There has been 2 x 10mm SY cables installed as well where the earth is obviously the same size as the line conductor.

Regarding the vibration issue, unless I’m missing something or not thinking fully, what difference would a stranded core cable make to a solid core cable if both had a nice tight connection? Or is it not the cable coming loose which you are getting at?

Thanks.

The name flexible cable will be the clue here, seeing as the motors will be vibrating a solid core cable is more liable to snap in the termination than a flexible one.

Excuse me if I’m being ignorant but what makes you think a solid core cable will snap with a bit of vibration unless the copper had been nicked or damaged?

Something that is of solid construction, is more prone to breakages than something that is flexible, especially solid conductors.

Any chance of knowing what cable is used for the final connection.

Post#30 says the same cable as the supply is used to make the final connection

So it does Pete I missed that. More to this than meets the eye me thinks.
