Cheers for that.
I have tried all possible combinations of switches on and off, dimmer up and down (yep I was there for a while
) all showed O/C fail.
Going back to it today I have tested all the sockets on an individual basis and it's only the dimmer controlled one that fails.
Thanks for the tip about the socket tester I tried it and it shows all correct (although the tester does say it will not detect earth neutral reverse)
Now I know that I can test the twin socket as a 2 socket extension, but any ideas how I would (using the Apollo 600's Manual Test and the socket tester) enter the test results into PATGuard3 and print a ticket?
You've met our cleaners then
Seriously though there should be no problem about misuse of the sockets as they're 7ft off the ground and on the back of the unit, the technician for that area is pretty switched on (no pun intended!) so should be no problems.
