“Domestic” Cable for Motor Applications

[IAmSparkytus!]

Good afternoon all,

First time posting on here so not sure if this is the correct place to post this but I’m sure you will all correct me if it isn’t.

My query today is whether anyone can see a problem using twin and earth to supply motor units fed from C rated MCBs?

I have enquired with an NICEIC assessor who says he doesn’t see the problem with it but still remain unsure and uncertain within my head.

Maybe this is unacceptable in all circumstances, maybe it’s ok for shorter runs but not larger runs, could be that it’s perfectly fine.

Please let me know your thoughts! Thanks.

A few more questions if you don't mind..

1. As Pete asked, do the t/e cables just go through round compression glands?
2. You mention a couple of motors have been connected in SY cable; have correct glands been used?
3. What supports the t/e cables where they travel from the rotary isolators to the motors themselves or are they hard up against the wall?
