Afternoon all,
I've started a job last week in a cricket club and been asked to take over from another sparks who did the first fix. He has since disappeared and no one can contact him, which has proved most unhelpful, namely in figuring out what he had done and ensuring that there are enough cables for what the client wants.
One of the clients requests was a 'last man out' switch, whereby all the lights in the premises could be switched off, via one switch at the main entrance. To achieve this the original sparky installed a 1.5mm t&e from the main entrance, directly to the fuse board. There will be 4 lighting circuits on different phases, so is there a device or perhaps a series of relays, that would enable all the lights to be switched off via one switch. I've not heard of such a device, but can see how it would theoretically be possible. The other point to note is that there will be emergency lights, so simply interrupting the supply would then result in the batteries being used to power the lights all the time, while no one is in the club.
As I said, the first fix sparky has gone AWOL, but he must of had an idea of some sort to make this 'last man out' switch, just not sure what that is. Just to mention, apparently he is an actual electrician who's been doing it for years, not some bloke from the pub.
Anyway, I would appreciate anybody's thoughts and I appreciate the sun is shining so not expecting quick replies :cool4:
Thanks in advance,
Stuart
