Re: Safety testing. Do you think this is over the top?
a) If the customers getting electrical shocks off it. There is a loose or bad earth connectiont and that’s why you will be going out to fix anyway
b) If its tripping electrics, its got an insulation fault and thats why you will be going out anyway, the earthing cisrcuit is going to be fine because its done whats its supposed to have done
Basic tests that will cover you for any eventuality.
1) Make sure the appliance has good earth continuity to the nearest copper pipe of earth pin on something else plugged in on another socket
2) Make sure it passes the earth loop.
If both of those are okay, even if it develops a fault, the fuse protection system will kick in and nobody will get hurt.
Asshole cover my back, I dont have any spine management who mainly dont understand what you do anyway come up with these lists orr else why would they issue you with a voltage tester when you already have a multimeter
