Will be in a state, if our friend is in fact a Electrical Trainee or similar that is creeping out of domestic work.

Please don't judge. You don't know me, I don't know you. It's a private school. Only small place. I'm not creeping out of domestic. I just do what I get. I now do professional cctv systems and intruder alarm systems. I didn't know until I tried it. It's unfortunate I can't do the same with industrial work.

Competition should be encourage, it provides value for money to the customer who is king

And of course customer feedback from healthy competition is the breakfast of champions and aids improvement, which all professional electricians should aspire to!

Yes mate, when the market is already saturated with sub-standard electricians who undercut you at every turn what we should all do is encourage more competition!

WTF?!?

The playing field isn't level, and until it is, I will not be relishing in adding to that problem!

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
