What size cable do I need?

[Darkwood]

By the way did I mention that I have already connected probably over 10 machines for the same factory. Ranging from 2.5mm cable up to 25mm cable. Some machines are same physical size as this one that I was going to do and they do the same work. The only time they called back was when a machine was tripping. I set overload at 7kw. The motor rating was 7. So I changed the overload to 4-10kw and adjusted it to tiny bit over 7 which fixed the problem. All this was done over the last 5-6 years. I've also done conveyer belts. Forklift chargers. A few of the bigger machines I've done cost them around a million each.

This is what i was explaining before ... your delving into things without understanding them...
Was the Motor a 7kw motor?
Overloads are set in amp's (different motors may vary with FLC even though they are rated the same hence the O/L is in amps )
You should set your overload to no-more than the motor FLC rating ...if the motor trips this it means their is an issue - the correct course of action would be to test the motor, run it off load while clamping it then run under load if its running higher than its FLC their is issues to address. Sticking a larger overload and setting it higher than the motor FLC is not the way to go ... the cause of the overloading usually get worse and you may now have set the O/L too high and rather than trip the O/L the motor may sustain damage. A motor on a machine shouldn't really be running at FLC it should be adequate to meet the machines requirements with room to spare.

It sounds like you have been winging it a bit with the repairs and your post contradicts your thread ..if you have so much experience fitting large machinery why have you come on here with such a basic question regarding a smaller set-up to the ones you claim to have done?

Sorry yes I meant 7 amp motor and overload was only going to just above 6. There was no number on it. It was on border line.

The ones I've done were not larger then this one. A few where similar

Anyway, I think we all wasting our time here as I'm not doing the job so this thread should be closed. Thanks for everything anyway

Thank you, good luck and may your dog go with you. ( as Dave Allen may have said )

What's a Electrical Trainee exactly.

What's a Electrical Trainee exactly.

There is a training course for knackers who aspire to become electricians.

It lasts five weeks after which they are given a bit of paper which makes them believe they are now fully qualified electricians and they are certainly not - hence the title Five Week Wonder.

It seems there may be because of your mind boggling questions / posts you have been making and your less than professional attitude, some folk on here who suspect this is what you are and all I am going to say on that subject is "If the cap fits ....."

That - in a nutshell - is it.

Oh right. I did city guilds 2330 for 3 years. Then 12 week 17th edition regs. Still need to do 2391
