apt timer wiring

Foleyart

I had my electrician in twice yesterday to connect up my immersion. the first time after he left I discovered it still wasn't working, so he came back and it was a wiring problem. It was working after he left, however I discovered later that the timer still wasn't working it hadn't moved on. I am assuming that it is a wiring problem but I am loath to call him back again. I have some electrical experience myself and if someone could tell me what the problem might be, I might be able to fix it myself. Any help would be appreciated.

em timers can be a bit tricky, but APT ones are about as easy as they can get.


what model APT time have you got?

Sounds like he's an apprentice electrician if he cant wire a timeclock properly, he may have put the supply (live in) into the live out side of the clock, it would work when its switched to ON but wen switched to OFF the supply would be cut to the timer, so maybe its just a matter of swapping the connections, its usually wrote on the under side of the timer wat the connections are, the wire leaving the live out connection should be going to your immersion switch, and just check all the connections are tight when your finished.

And check that the connections have been snugged up properly - not loose and certainly not too tight.

We had a sparks put in one of those years ago and he didnt tighten up the connections adequately. As a result arcing occurred under working load and the blasted thing burned out. :mad:

Thanks for all the input guys, as it happens when I opened it up the clock re-started. It may be that it was jammed in some way when he tightened the screws. at any rate it is working fine now. Thanks again.:D

I dont want to alarm you, but that sounds like it may be due to a bad connection. With a load such as that (3kW) a bad connection can be a fire hazzard. This is an educated guess, so although I may be wrong you should call him back to check it out and not use the immesion until then!

The bad connection may be within the clock (faulty clock), so not the electrician's fault.

Thanks Fishdog, I did check the connections and they all seemed ok. I reckon it was the way the excess wiring was squashed up in the box when he tightened it up that caused the clock to jam. Any way it is working fine now but I will keep an eye on it thanks.
