While I'm no fan of Part P and I'm not defending it, perhaps you'd

That one has obvious contradictions. Eg: Look at the entry

to
sockets in both lists. (Item 1 in first list, 3&4 in second list.)

I guess it's one of those rules that nobody understands. A
(Scottish,
therefore not subject to part P) electrician told me you couldn't
even
replace a lightswitch in England without a certificate.

That is not what the list you posted said in things you can do.

+1

The list is also somewhat contradictory and stupid in at leas some
places.
Like:

DIY Not allowed:

Re-wire sockets or lights that are faulty and causing the fuse to trip


Allowed:

Replace a simple light fitting
Replace an existing socket or light switch like for like
Make repairs to loose wirings in switches, light fittings, or plugs
Replace light switches
Replace sockets

So if you have a light fixture with an obvious short, you can't
replace it yourself. And good luck enforcing that BS.

You're not allowed to install a "home entry system". What's that?
Security alarm?

I think they are saying that if you have a wiring fault you should
call a pro but you can throw a receptacle, switch or luminaire at it
to see if that fixes anything first.

I doubt many of us on the left side of the pond know much about
ring circuits but it might be confusing the first time you see one.

Not really, the main difference is the fusing. All pretty simple really.

The fusing isn't different at all.

Corse it is. Much higher fuse ratings with a ring.

No, if I made a circuit for sockets, I'd have the same 30A fuse, but have it in a straight line with one 30A cable. If the cable comes undone, no power. If a cable comes undone in a ring, 30A allowed through 15A of cable, fire!

The difference is instead of a 30A cable, we use two 15A cables.

Wrong again.

It is not wrong. The cables are rated lower than the fuse (which is ****ing stupid if one breaks).

And a lot less cabling is required.

It's fractionally more cabling actually as you have to complete the circle.

Saves on copper after the war....

Yes. But that isnt the only advantage of a ring.

There are no other points to it.
