Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

I wish I was as clever as you. I bet you even cleaned the nails in the fuse holders. :)

Hey Gregor

AB contactor and a (godawful) wire-nut (American wire connector )  pushing the contactor in?
More like Tennessee Redneck standard

That's what screwits (wire nuts to foreigners) are for, isn't it?  ;)

I think I still have a couple of the proper ceramic ones somewhere...

Oh, and don't forget the small mole grips on the isolator shaft. :)

You would have a fit if you had a look around this place, Mick. I really have found 30A fuses bridged with 1.5mm  

I don't work for them but I have full use of the facility but I also fix their stuff.

One guy using a circular saw had been "getting shocks" routinely.

He only told me when they were becoming "unbearable" 🤣

Sheesh....  LOL

The sort of place that forgot what H&S was when the first edition regs came out, eh?  :)
I've seen a couple. Best not to open too many doors 'cos you don't really want to know what's inside!

One of the funniest Simpsons episodes, Homer gets to be "safety officer"

He walks around:

"YOU! Be more safe"
"Hey YOU! Be safer" 🤣

I found this hilarious because it's reality, even in ISO9001 certified facilities.

Purely symbolic 😂🤣

All you really need is to need a tool to get in (a screwdriver will do) and have a label on the door saying "Danger of death, no unauthorized access. Contact: Fred Bloggs". It doesn't matter that Fred is hardly ever available. What's on the other side of the door doesn't matter. :)

I come across these virtue-signaling guys all the time; there might very well be an approved safety mat, laser-scanner and with all the credentials BUT they are tied into a "HOLD" command. The potent energy is still all over the machine.

I offer a ZEH (zero-energy-hold) package that removes all energy from the machine. The virtue-signal guy? Crickets because there is money involved.

It's all BS
