Two light circuits off a single FCU?

[PrenticeBoyofDerry]

Rob_Quads,
It's considered minor work and is not notifiable to the BCs but that does not mean it should not be inspected and tested to assure it is safe.
Issuing a MWC would do that.
The work should still comply to part p even though non notifiable and a relevant standard to assure it does is to follow the guidelines set out in BS7671. The outside lights are different issue.

You see this is where its all very confusing for us mere mortals. Where is there a list of things that do not fall under Part-P? Does everything. Do you need to get replacing a socket tested?

The way I read the paragraph below adding a new socket and FCU into an existing ring main is not covered by part-P and thus would not require testing.

The approved document for Part P from the office of the deputy prime minister (ODPM)
lists the following examples of electrical work that IS allowed without notification, and
thus is NOT applicable to Part P:

Work consisting of:
> Replacing any electrical fitting including socket-outlets, control switches and ceiling
roses.
> Replacing the cable for a single circuit only, where damaged, for example, by fire,
rodent or impact (a)
> Re-fixing or replacing the enclosures of existing installation components (b)
> Providing mechanical protection to existing fixed installations (c)

Work that is not in a kitchen or special location and does not involve a
special installation (d) and consists of:
> Adding lighting points (light fittings and switches) to an existing circuit (e)
> Adding socket-outlets and fused spurs to an existing ring or radial circuit (e)
> Installing or upgrading main or supplementary equipotential bonding (f)

All domestic electrical work falls under Building Regulations Part P. Most of this is to ensure safety of the installation.
Most electricians install according to the Wiring Regulations (BS7671).
The difference is that BS7671 is not statutory (=law) but Building Regulations are statutory (=law).

If you read carefully what you posted, you will see the word NOTIFICATION.
This means that you have to notify your intention to do electroical work in certain locations and certain types of work.

So, your

The way I read the paragraph below adding a new socket and FCU into an existing ring main is not covered by part-P .

is incorrect.

The work is covered by Part P. as long as the new socket is not in one of the notifiable areas (eg kitchen, bathroom, outside, etc) then you do not have to notify it.

BUT you say

and thus would not require testing

. Of course you would test it.
You need to confirm that the ring is still complete, that the insulation resistance is within limits and that the EFLI is still within spec. If there is an RCD on the circuit, does that operate within its spec?

When you change the brake fluid in your car, do you roar off down the road at 70mph? You test and check it first.

OK So all work applies to Part-P thats fine. I don't have any problems making sure the work is to the right BS standard, I want it to be which is why I started the thread (rather than just ignoring all the standards and guessing)

Its the whole "You need to have it tested to be compliant with regs" etc.

Am I reading the Part P 1.30 doc incorrectly as I read that as saying that while the work needs to conform to BS7671 it is not a requirement to have it tested

Yes 2 double sockets is fine as its an extension to an existing room which already has suffient electrical supplies.

All new electrical circuits have to be tested regardless of whether part P applies. This is to ensure they're safe to use.

This is not a new circuit, this is a change to the existing circuit which comes back to the whole do you need to fully test any change i.e. changing socket?

1.30 (with my emphasis):

Non-notifiable electrical installation work
must also be carried out in accordance with the
requirements of BS 7671:2001 or an equivalent
standard. However, it is not necessary for the
work to be checked by a building control body or
alternatively carried out by an installer registered
with a Part P competent person self-certification
scheme.

That's not the same as you not needing to test according to the requirements of BS 7671, IF you want to comply with BS 7671.

Testing is always an issue when it comes to DIY electrical work....

 

[ban-all-sheds]

And I do wonder, if they were honest, how many electricians would admit that in their own home, when they know that they are starting from a position of the existing circuit being perfectly OK, and they know that when they added a socket they didn't mess anything up, they do not carry out a full re-test of the circuit....

 

[Rob_Quads]

Gotcha - So to fully comply with BS 7671 you would need it tested but proof of this testing is not required by Building Regs

So you can do all the work to BS 7671 and then don't do the testing your 'technically' are not BS 7671 compliant but other than that its fine.

Proof of this testing is required for compliance with BS 7671.

So you can do all the work to BS 7671 and then don't do the testing your 'technically' are not BS 7671 compliant but other than that its fine.

It might be fine. You might stake anything and everything on it being fine, but without testing you have no proof that it is fine.

But then 'twas ever thus, and life has gone on, and there are no piles of corpses in the parts of the streets not closed off because of burning buildings....
