I need 10cm extension of 1mm cable

Found 17th Oct 2016
The extractor fan cable is too short by about 10cm! I need to get a 10cm length of 1mm cable to connect via a block.

Where can I get 10cm? Any other ideas? Cut a 10cm off cut from a lighting cable????

Extension lead? No cutting required



Bathroom wall mounted extractor fan so can't use extension lead

wilko

screwfix, Maplin, wickes, b&q all used to sell cable by the metre.

Ask on Freecycle, Gumtree, Preloved, and Streetlife - someone will have spare cable to replace the old one for free.

Local Hardware store will sell by the metre or look in Diy store as the sell cable in packs various lengths. I bought extension lead for £5 at wickes to replace vacuum cleaner lead as cheapest option. Maybe your best bet to replace the entire lead if you can? Joining is possible using a cable plug though like screwfix.com/p/m…232

Any nearby houses having renovations / building work done, with a skip outside? You often see offcuts of cable ( and other useful things) in them!

stick a plea on fb a friend of a friend will probably help.

how are you going to connect them?

lighting cable is usually 0.75mm too , you'll need to crimp the connections if you are burying them in the wall too

A connecting block

where is this connection going to be inside the room ?

In the wall, just before it goes into the extractor fan. If the block can sit inside the fan, even inside the fan itself.

Yup Wilko is about the cheapest, but you will need to buy a metre.

Or...take the plug off an appliance with a suitably long cable. chop off what you need and put the plug back on...

I think a block will be a breach of regs if you bury it in a wall. You need to crimp the wires. I believe.

Yeah, but a box wouldn't be required if the joint was soldered and shrinked, far superior to a mechanical joint.

pull the wire it may be long enough or have u already done that

It has stretched as far as it can go. It was not a long cable originally, which is stupid of the electrician!

you cannot bury joints within the wall, you must either run a new continuous unbroken cable or make a joint considered maintenance free, this would either be a soldered or crimped joint.

LOL. I won't go this far, rummaging in other people's skip. Reminds me however, I should have kept the electrical cables I threw out in June that were left by the electrician when he connected the room thermostat

No. This is too much, not to mention some people are odd about their rubbish and would not appreciate someone rummaging through their bins. I certainly would take offence if you went through my rubbish.

You've had an extractor fan fitted and the electrician has left himself short of cable..?


Wago connectors, makes life very easy...

Oh look

I was right. You cant bury a connection box in a wall.

Another case of marking down by idiots. I would have brought my 17th Edition book out & flashed my certificate but really can not be bothered sometimes.

Keep giving dodgy advice!

The fan was there when i bought the house and the fan connections were at the bottom so the wire was adequate for that but there was not much slack. I have replaced the fans since then and most fans have connections at the top and cable entry at the bottom, which is why i am only 10 cm short, the height of the fan really.

So the stupid electrician originally fitted the correct length cable and you are trying to replace with a fan that isn't suitable?

Just buy a fan with connections at the bottom

Or rotate the fan casing 180 degrees

I fail to see where the electrician was being stupid.

Nonetheless, cant you replace the length of cable back to the supply?
Lighting circuit/switch/junction box?

If not follow above advice, joins buried in walls or cavities is a big no, possibly a junction box in attic if cable is routed that way would enable you to lengthen the cable..?

Accurate advice really needs an accurate description of the install tbh..

Location of fan? cable routed from? access above? etc etc

He should have given adequate slack in the cable if he understood that fans can come with connections both at top and bottom for future replacement. If he is not stupid, he is not very forward thinking!

I have turned the fan upside down to fit the cable but it says on the installation instruction that the fan should be installed the right way up.

I'm not a electrician, I'm a degree qualified engineer and when I sat my 17th edition, not everyone on the course passed, a substantial amount of electricians did not, many probably never do. But, It should be common sense not to bury something in plaster that may require inspection or repair.
Actually, only part p qualified can work on any part of the electrics in kitchen or bathroom, but if someone is competent and it is their own home, well....

As far as I am aware, new installations must be carried out by a part P qualified electrician but replacements do not have to be done by a part P qualified electrician.

Not in this case. Any extension of wiring in a kitchen or bathroom is classed as an adjustment to the installation which means it needs to be done by a part p qualified electrician/installer/competent person.

It is not a straight replacement.
