You've removed the overload? Why?
Put it back!

The unit will be wired as shown in the animation. As Allan said it doesn't require a neutral.

Allan that was OTT even by my grumpy standards.

oops sorry about that.
Wasn't meant to be that's why I put the smiley faces on.
Just trying to make the guy realise what he's messing on with !!

Removed the overload..........eh what's that all about it's still in the photo wired up fgs !!!!

Do what my old boss taught me .... if you dont understand it physically push in the contactor to see what happens.....!!!:nonod:
I asked wouldn't that over-ride any control and more so safety systems...which he said 'we are just proving that the contactor is letting power through and you also can find out what it does as well if there are lots of them' ...


I shook my head in disbelieve and never took his advice again.

The poorest advice i ever received hence i dont work for him now as i rose past his intellectual level nearly 25yrs ago in my apprenticeship.

Even at my age I still to this day enjoy the challenge of finding a fault
The start/stop button in the OP is basic stuff and any fault should be easily traced with a couple of 'dead tests' on the control circuit.
No need whatsoever to close the contactor manually onto a possible seized motor..............dirty pants time if you do lol

I do admit i do it in certain circumstances on systems i know and where even if motor seized the couple of seconds test wouldn't really be of concern... like say a pump etc it can save alot of time in some circumstances and instant diagnosis but yes agree that its not for routine fault finding methods especially on machines your unfamiliar with.... or the consequences could be dire!!!!

I must have pushed contactors in 1000’s of times. But I didn’t fall in to that category.

I learnt not to be an idiot by example not by experience thankfully :iagree:

Bet you still closed you eyes and turned your head away

Why? Can't see what's going on then.

Only had it go wrong once with open type contactors on an old lift motor. Pushed the main and down contactors with my hands and the speed contactor with my right foot. I over balanced and fell over.

today new head looking at the pictures i noticed that the load was on the wrong side changed it around bingo works perfect

i was a bellend about the coil but did not know that you can use 415 to pull in the coil as well as 240 going across two phases or going phase to

neutral so thanks guys all the posts they do help even if it gets a bit heated no offence taken at all,

You’re not the first and you’ll not be the last. Don’t worry about it, you won’t fall for it again.
