Few questions for an electrical installation

[MikeGT729]

Hi

Firstly I don't have any electrical qualifications, but I am undertaking an installation which will be certified by the local council, however I have to get it to first fix before they will come out, so want to ensure I get it right first time.

Installation is in a utility building, with its own mini consumer unit, 63a main fuse, with a 32a and 6a breakers (if I remember right, I'll update this if I've remembered wrong). I've already installed all of the conduit, 20mm pvc. Wanting to use conduit cable, as T+E would be too tight of a squeeze in places.

Load will be minimal, going for 1.5mm for lighting (LED), however not sure what to use for main wire in from house and for the sockets circuit. Fuse where I'll be connecting to in the house consumer unit is 32a.

2 main loads on circuits will be tumble dryer and an electric heater, both around 2kw. Also considering a solar battery storage at some point in future if that impacts. What size cable would be required?

To summarize, need to know

Cable size for house to mini consumer unit

Cable size for sockets circuit.

Let me know if you need more info.

Much appreciated in advance

Mike

Hi Mike, if you are attempting an electrical installation you should get a copy of BS7671 and have a read. This will answer some of your questions and get you thinking about things.

The fee your paying to the council to certify the work you may aswell put towards paying a sparks to do it for you. Least you know it will be done correctly then, it doesnt sound like a diy job to me

I will come straight out and say I am sceptical and think you might be a DIY'er doing a notifiable job and just saying you have told building control and come on here looking for step by step guidance.
Not being funny but the cost of getting a qualified electrician in to do the job properly and the cost of notifying building control won't be much different. a non qualified person going via the council building control will typically pay around £400+ in fees. then you have materials on top.
its probably no more expensive to get a electrician in they will do it properly, certify and notify it for you.
So don't go working beyond your abilities and call a professional in.

Best put up your location and pay a local spark for their time and advice

Just saying

from the questions you are asking, i very much doubt that you are proficient enough to undertake this work. it's a lot more than installing a few cables and fixtures. there's calculations involving maths, cable ratings dependant on the installation method, and a lot more. this is why it takes 5 -7 years to train as a sparks.

Not sure that will help someone with no qualifications come to think of it the same can be said of people with qualifications

This isn't a complicated install, and it's being checked and signed off by a part p certified person, so I don't see the issue?

I just need to know what size cable to use for the 2 elements I've noted, and that should be all I'll need.

I thought you said it was a building control signing it off? normally they are more than just part p. part p means bugger all when you break it down., my local council insist on using known and experienced electricians with nvq3 2394/2395 etc etc for building control ordered inspections. the electrician working for the council is in effect a temp. building inspector and is covered by the council and not his own business liability.

Also, I sure as heck wouldnt sign off on other peoples work. only stroma and i think napit allow certain assessed sparks to do 3rd party sign offs.

Also maybe I am wrong but i think as part of 3rd party sign offs you are meant to get the design and plans approved by the 3rd party electrician before starting, then at first fix and finally 2nd fix and initial verification for certs to be issued.

I rang BCO and asked whether I could do the install myself, they knew I wasn't qualified, and they said yes, but I would have to have the electrician who works for the council come out and certify, which costs £360, which seemed fine given the few prices I'd had for other jobs.

If, and I say if building control's are checking and signing this off they will , or should inspect at each stage ...

You are not comparing apples with Apple's. £360 plus VAT is for them just coming to inspect..... No advice, nothing else

 

[MikeGT729]

OK, and I assume design is a stage? I'll give them a ring on Monday and find out for sure

It's £360 Inc VAT. And this isn't BCO, this is the council's own sparky

Design won't be a stage.....
