Anyone who treats coax cable like that would not be fitting an aerial for me. I hate to think what his terminations are like.
 
Less dodgy, more just stupidity courtesy of one of our “multi-skilled” technicians. Bear in mind the multi-skilled guy has an electrician to guide them on their shift and they supposedly checked all this together!

Yesterday a cooling fan wasn’t working, they went to it and reported back at shift change when we started that the contactor needed replacing because it wasn’t coming in. We asked if they checked the voltage at the coil “yeah, 230” was the answer.

I suspect not somehow, but at least we know why it isn’t coming in...

The machine wasn’t needed until this afternoon so we left it for them to wire up the coil this morning, and hopefully learn something in the process.

They wired the coil into a nearby transformer in the machine. We got called back just after shift change for cooling fan not working and “smell of burning”. That’ll be 230 through the 110 coil then.

In fairness the almost identical machine next to it was wired the same way, just went into a 230v coil.
 
Reminds me of the time I got called out because the new contactor coils weren't lasting long on a roof fan. I couldn't get the on-site maintenance bloke to understand that 240V coils don't work well when fed with 415V. 'But there's a neutral there!' he kept saying. That blue wire was of course L3.... Amazingly all 3? he tried lasted over a work day under those conditions.
 
Back when I was a rookie, I was given a 230/400v motor to fit on a machine.
It lasted almost 2 weeks before it gave up.
I had wired it in delta because my total lack of understanding led me to believe that star was only for starting a motor.

Boss was not happy but I learned a valuable lesson!
