taking over a rewire

[Bright.Spark]

Ive recently taken over a rewire as the original sparks wasnt qualified to carry out the work. Ive just got a few issues Im not sure about myself.

Firstly, they have wired a socket to the boiler on the ring and are planning on putting it on a plug top, I thought this was a no no and the boiler needed to be on a dedicated supply. Am I right?

Secondly, they have used IP rated fittings in the bathrooms but there the fittings where you need to put the heat prove sleeving over the cores. Its been wired three plate method but all the cables have been bought into the fitting, now I was under the impression that it need to be joined in the ceiling and a single cable bought into the fitting to eliminate the cables buring. Could someone please clarify these things for me. Thanks.

They should be installed as per manufacturers instructions

Thanks.There are no specific requirements,but there are regulations on protecting cables from heat damage,these would need to be taken into account when deciding if it was safe to terminate in a luminaire which will be subject to high temperatures.IMO taking 70degree PVC cables into such a fitting may not comply with the regulations...unless all conductors are sleeved with silicon sleeving and high temp connectors are used.

.......................You need to take particular care in providing a cert for the job....ONLY cert work that you have carried out....be very specific on the extent of your work and the work that was carried out by others.

I thought it says in the regs you need a isolation switch for the boiler or am I getting it confused with the immersion heater? So a boiler on the ring on a plug to is acceptable?
Thanks for the replys on the light fittings, I think I will join them by a JB in the loft then bring one cable into the fitting, I can terminte the 3 core and earth for the fan better that way too. Thanks guys

plug and socket is isolation

Where?

So a boiler on the ring on a plug to is acceptable?

537.3.2.1 States the a plug and socket-outlet is an acceptable form of switching off for mechanical maintenance
537.5.2.3 States that off-load isolators (disconnectors), fuses and links shall not be used for functional switching (no mention of plug and socket-outlet there)

Just to add to the advise
I believe a boiler must have isolation of both poles, so a single pole switched socket to the boiler may not comply

Add a fused connection unit for the boiler. Personally think boilers plugged in look rough

 

[Deleted member 19807]

if i do a rewire the boiler goes on its own circuit, but if you find a plug and socket then it complies but as said above a bit rough.

 

[Amp David]

Same here if I had done thejob from scratch it would be on its own radial too.

 

[lj.l]

yes from scratch a new circuit. on an oil boiler I always fit a twin socket so the pump and boiler are fused at 3a each and it complies because when you unplug it ,its isolated,gas bolier is a fused spur

 

[Bright.Spark]

Thanks guys I decided to remove it from the ring and put it on a dedicated supply with a spur. Just one more question do I need to fit a heat detector in the kitchen? The smokes have been wired but not the heat?

Not meaning to have a dig honest but I am not qualified and I know that this information is clearly documented in numerous books that any qualified and training sparky will have in their possession I always carry mine in my toolbox as you never know when you'll come across something that you don't know or you'd just like to check for peace of mind:thumbsup

You don't have to use a heat alarm UNLESS the kitchen is not separated by a door. I would also check that the required distances from walls etc have been adhered to and make sure that they are all close enough to every normally habitable room.

hey 1shortcircuit, I did just dig out the OSG and saw the quote you just wrote I just couldnt be bothered to hunt through the van and look for what I needed. Lazy I know. Yea no heat detector is required as the kitchen is through the dining room and at the back of the house. Thanks all for your help though Ive just not been house bashing long and needed to check a few things.

I only know it's in there because I needed to know exactly the same thing last week. I am trying to get into the habit of looking through my books for the answer as it's quicker and helps to learn the answer. I also find it satisfying when I do find out exactly what I needed to know:thumbsup

Like I said, mine in my toolbox ready and waiting and protected by a plastic bag
