Look at Part P of Schedule 1 and Schedule 2B near the bottom.

The Schedule 1 piece gives the scope of where electrical work is
controlled. This is in a dwelling and buildings associated with or
supplied from it.

Schedule 2B lists exemptions.

DIY work following BS7671 is not exempted.

" SCHEDULE 2B

Regulation 12(5)

DESCRIPTIONS OF WORK WHERE
NO BUILDING NOTICE OR DEPOSIT
OF FULL PLANS REQUIRED

1. Work consisting of -

(a) replacing any socket-outlet, control switch or ceiling rose;

[does not say that you cannot touch the ring main]


You are looking at it the wrong way round.

These are *exemptions*.


You are not exempted from touching the ring main as you can "replacing any
socket-outlet, control switch or ceiling rose;". To do this may entail
working on the ring main. Simple. Obvious.


I didn't say that you can't "touch the ring main"

First of all it is a "ring final circuit".

Secondly one is allowed to change fittings.



Other works are controlled.

(b) replacing a damaged cable for a single circuit only;

[so you can replace the ring main or a radial circuit]


No.


Yes! You are exempted if the cable is damaged and needs replacing. hat may
mean the whole ring main. Simple. Obvious.


Of course. However, it is fairly unlikely, and the intent is that
installing a new circuit is a controlled activity.

They have simply listed the exemptions because they thought that they
are fewer in number than listing what is controlled in detail.

By the way,,,, I am not seeking to defend this nonsense legislation.
I've repeatedly said that it's bull**** and achieves nothing because
it is unenforcable.

I would remind you that it was enacted by your friend Twojags and his
cronies. I am sure that if this ever does become a big issue (which
is unlikely), that he will seek to distance himself from it in exactly
the same shameful way that he has from hunting legislation.



(c) re-fixing or replacing enclosures of
existing installation components,
where the circuit protective measures are unaffected;

(d) providing mechanical protection to an
existing fixed installation, where
the circuit protective measures and
current carrying capacity of conductors
are unaffected by the increased thermal insulation.

2. Work which -

Work which -

(a) is not in a kitchen, or a special location,

(b) does not involve work on a special installation, and

[So the above two say any work as long as it is not in a kitchen or a
"special installation"]


No. You haven't read it correctly. The *and* at the end of (b)
means that conditions (a) (b) *and* (c) have to apply.


No "and" at the end of (a), so (a) not joined with (b) and (c).


There doesn't need to be because there is a comma.

I know that your English abilities are not strong, so when something
is expressed as (a), (b) and (c); it means (a) *and* (b) *and* (c).




So you can't plug in a low voltage garden light set to a socket on the
outside of the house? Me thinks not.


It doesn't say that. It is only a special installation if the
lighting set is NOT a pre-assembled lighting set bearing the CE
marking referred to in regulation 9 of the Electrical Equipment
(Safety) Regulations 1994


or electric power installation, an
electricity generator, or an extra-low voltage lighting system which
is not a pre-assembled lighting set bearing the CE marking referred to
in regulation 9 of the Electrical Equipment (Safety) Regulations
1994[8]


- an electricity generator
- an extra-low voltage lighting system which is not a pre-assembled

lighting
set bearing the CE marking referred to in regulation 9 of the Electrical
Equipment (Safety) Regulations 1994[8];

[what is "extra low voltage"? So this appears to mean you can install 12v
downlighters and run the cables]


Less than 50v AC or 120v DC


So, you can't fit 12v downlighters. So, that is why Homebase do not sell
12v lights anymore.


You can fit luminaires anyway. 12v is less than 50v by the way.
