I have fitted recessed contacts ( the ones about 20mm with a rectangular plate & 2 screws) to all my new UPC doors, front side and two to the patio doors. Took some drilling with the metal channel inside the doors & frame but Not had any issues with them at all.

Thought that would be the case, just seamed a good idea. What market are the exodus smoke & heat detectors designed for then. Surely they can't be used in a commercial environment either. Thanks for the help.

I am currently first fixing a new house that I am doing up to move into. I am planning to fit aico smoke detectors, as I normally fit in other rewires, however I am fitting a Texecom premier 24 & com2400 module. I would like the smoke detection system to be able to trigger the outputs on the...

no not a diy job. i am a partp registered electrician. everything tested ok, checked for loose terminals all sockets on circuit. Dont think its the power supply as it does it with a new laptop as well. Just wondered if anyone else had seen it before.

I have a strange issue with my TV, Whenever i plug a laptop, wii or anything with a transformer in to the living room sockets the tv image goes blank, just for a few seconds. I have just rewired the house completely, Its an LG lcd tv, high level socket on same circuit. Has anyone come...

I have a job tomorrow to do some electrical work in a kitchen. The job involves moving existing sockets and adding a few more, the rfc is present at the existing sockets and already checked continuity. I will be issuing a minor works cert and notifying the work, the problem i have is the...

Thanks for the quick reply. might have a go at working it all out if i get chance this weekend, Good revision of my 2330 stuff!! would also be interesting on the sizes of cable required, taking into account for volt drop etc. Having a seperate power supply from the pub? would that be a...

Hi, Been asked to price a job which has the possibility of wanted a power installation to 10 log cabins added to an existing campsite which is part of a pub. Having only just started out and purely focusing on domestic work (only a domestic installer) i turned the job down, due to it been...

I think i could be able to make do with 7 in the room instead. Split 4 and 3 on the dimmers. Is there any alternatives? They need to be flush and dimmable.

Why dont you use plasterboard instead?, mdf i would imagine would get very heavy.

I have a very large room which i want to put 11x mains downlights in. The lights need to be able to be dimmed, If i go for 35w bulbs and split the circuits into 2 i could have 5 x 35w = 175W and 6 x 35w =210W But i can only find the double dimmer switch in the chrome i want in 2x 250w max...

Thats what is confusing, every circuit got excellent readings for loop impedance and insulation, polarity is also correct on every outlet. So dont understand what could be wrong, not come accross this before other than in older houses with a very small outdated incoming supply.

Hi, I have recently completed some electrical work at home, which involved moving (about 10m with suitable 80A isolator) and renewing the consumer unit. This is all complete, passed all tests and i labc have checked the work. I have a few problems, 1 The installation seams to be using...

Hi When testing an RCD circuit to get tripping times, with a split load board should i expect all circuits on the RCD side to trip at exactly the same time? I have just tested mine and i get a varied reading for each circuit, only about 5ms between times but does this sound ok? Cheers, Adam

iam sure that it was 8.7ms but will double check. Its a fluke tester i used.

:-) cheers, yeah that wa going to be my next question! Am i right with the 6mm swa having a cpc csa of 6mm (even tho i have used 3core and also used the armoring in the gland or will the csa be higher)?

cheers, will get it sorted. Do my test results look reasonable so far?

well yeah i suppose you could (if you were daft enough!) But surely you could also force a piece of stiff wire into a normal plug socket. Can you get closed grommets that size? the grommets i used were the ones that they provided when i picked up the isolator. Is it a major issue, i.e...

well yes, i meant you couldnt get a finger into the enclosure and their is no chance of any water getting in. The wire exiting the bottom of your enclosure which has a quite tight bend, does it go through metal as it leaves the cupboard? It goes through the plasterboard then drops down to...

Hi, thanks for the replies, The connections are made in the box via a bank of DIN rail terminals. The isolator does have an open grommet at the top but with the two tails and earth in each, you could not get anything else inside. I did take into account the grouping factors when i...
