Garden PIR install from radial light circuit?

.. as others have said, if you need to ask questions like that, you really shouldn't be even thinking of doing it.

So earthing of the steel armouring isn't required? Contrary to the threads that I posted?

If you think that my statement was saying that, then what I said applies even more certainly.

If you have armour, it certainly has to be earthed. If you don't have armour, then there is none to earth.

Kind Regards, John.

Here's the stuff I bought (although in shorter quantity)

Any of these as well?

Sorry, I misunderstood your reply, I'm clearly not an electrician and if you had expanded on your comment, I might have fully understood the first time.

Thanks for the clarification all...

All,

Had a busy today and managed to fit the external light, supply and switch cabling and wire the junction box.

None of it's connected to the light ring yet and won't until I get a spark in to connect and certify it all along with the remaining lights that still await installation into the room but I just wanted to thank everyone for their help in this thread.

I used 1.5mm cable throughout, the junction box is a 20amp max unit. The switch will be mounted at 1200mm from the floor which I believe is the requirement by building regs.

Do let me know if you spot anything glaring, besides the state of the room

Here's a few pics.

Inaccessible JB.
No protection for the cable through the wall - I use 20mm conduit.
Is sealant likely to damage cable?
The switch height does not apply to your property.
New build it will be between 450 and 1200mm from ffl.

It is accessible, once the ceiling is up, the floorboard directly above the JB is lift-able for servicing the radiator connections.

The wall of this house are non-cavity 11" solid brick, would protection for the cable through the wall really be necessary? However I have some conduit and so will use that instead for the rest of the install

Is sealant likely to damage cable?

No, its of the non-corrosion type specifically for electrics/electric cabling.

The switch height does not apply to your property. New build it will be between 450 and 1200mm from ffl.

Ahhhhh well, its a good height to stick with to be consistent throughout the rest of the property
