I have a 1500W bench saw that has served me well for 15 years (Performance Pro - B&Q special). It's got an NVR switch and a temperature overload, as you'd expect.
Yesterday I lent it to someone I know who lives on the other side of town. Showed him how it worked and off he went.
Get a text from him today saying it's not working so I drove over and right enough - it doesn't!
It was plugged into an extension lead in his garage and pressing the switch would either do nothing, or spin for half a second and shut off. Exactly the same behaviour as if the temp overload had tripped, except it hadn't been used and when I took it's cover off the motor and switch were stone cold.
OK... garage electrics...? So we took it to his house and plugged it in there (via the same extension lead) - same problem.
OK - low voltage so the NVR relay doesn't have enough juice? He had a multimeter and we got a healthy 246V at the plug so not that. A jigsaw plugged into the same extension works fine.
I took it home, plugged it in - works! Took it back, plugged it in - doesn't work! Rinse... repeat...
Any thoughts? If not voltage or temperature then the only other variable is current, but I'd have expected the extension fuse to blow or the MCB to trip...
I'm flummoxed...
