on this occasion BAS you are incorrect..
No, I'm not.
commas in a list following an "or" indicate further or's..
that first and you inserted should be an or...
No, because if you look at the way the text is actually written it says
2. Work which—
(a) is not in a kitchen, or a special location,
(b) does not involve work on a special installation, and
(c) consists of—
(i) adding light fittings and switches to an existing circuit; or
(ii) adding socket outlets and fused spurs to an existing ring or radial circuit;
the (a), (b) and (c) are subclauses (I don't know if that's the right term, but hopefully you'll see what I mean), and they are linked by the "and" just before (c).
The structure is
Work which
subclause (a),
subclause (b) and
subclause (c)
It's in English, so just like "fish, chips and mushy peas" means you want fish
and chips
and mushy peas, it means
Work which
subclause (a)
and
subclause (b)
and
subclause (c)
subclause (a) is:
is not in a kitchen, or a special location. The "or" you were using just works on
kitchen &
special location.
subclause (b) is:
does not involve work on a special installation
subclause (c) is:
consists of (i)... or (ii)....
So it means
"Work which
is not in a kitchen, or a special location,
and does not involve work on a special installation,
and consists of adding light fittings and switches to an existing circuit or adding socket outlets and fused spurs to an existing ring or radial circuit".
With your interpretation you'd drop out from Schedule 2B with "non notifiable" if you got a match on any part of 2(a) or 2(b) and a match on 2(c),
e.g. an ELV lighting system which is not a pre-assembled lighting set bearing the CE marking etc etc.., you've just bought a bunch of ELV luminaires, a roll of 1.5mm² T/E, some sleeving and some switches etc, and you're going to install them in the living room
You say not notifiable
if not in a kitchen , or a special location, or does not involve work on a special installation
and
consists of adding light fittings and switches to an existing circuit or adding socket outlets and fused spurs to an existing ring or radial circuit.
So are these lights not in a kitchen or in a special location or are they not a special installation.
You get a match there. Because you've linked them with an or you only have to match one of them, so you come out with a "yes" because it's not in a kitchen or a special location.
If it were written as a Boolean logic expression it would be
m = x OR y
it only needs one of x, y to be <TRUE> and m is <TRUE>
in this case with
not kitchen or special location, &
not special installation we get
m= <TRUE> OR <FALSE>
m= <TRUE>
Then we go onto
and
consists of adding light fittings and switches to an existing circuit or adding socket outlets and fused spurs to an existing ring or radial circuit.
There's a match there - it does consist of one of those:
adding light fittings and switches to an existing circuit .
So the first half is <TRUE>, and so is the second.
It becomes [Not Notifiable] = <TRUE> AND <TRUE>
i.e. [Not Notifiable] = <TRUE> - installing those lights which are not a pre-assembled lighting set bearing the CE marking etc etc is non-notifiable.
Which is not the case.
