MK Masterseal SFCU - ok for lighting drop off RCBO'd outside 20A radial
 

We have a 27ft long dark wall, no road or adjoining lighting.
I would like to fit an external downlight & PIR.

Nearby exists a MK Masterseal socket outlet on a 20A
external radial to an outbuilding, RCBO protected. Above
ground it is HiTuf changing to SWA to enter ground.

I could fit an MK Masterseal SFCU 56410 alongside the
socket, creating a fused spur at 3A, w/double pole switch.

Q: Is that a legitimate usage of the SFCU 56410?

This would avoid running another cable alongside the existing.
I suspect it is considering likely popular for fountains & such.

Struggled in the dark for donkeys years and just stumbled
across the item in the MK catalog p206, guide #46 :-)

Great. I have bought a Masterseal SFCU and it works ok.
Using the black pond rubber cable left over from a TLC order.

With that length of wall, several lower-powered lights and PIRs
might provide better coverage. Most types (but not all) if you
interlink them with 4-core cable (live, switched live, neutral,
earth) in parallel, any PIR sensing movement will trigger all
the lights.

Noted, and thanks.

You're not meant to use flex for fixed wiring.

Even for the SFCU to light drip-loop?

Cable to the Masterseal-SFCU with be HiTuf or SWA
or Singles in black heavy-duty conduit (I have all spare).

Cable from Masterseal-SFCU to Light drip-loop would
be about 9-12-inches black ?TRF07? rubber from TLC.

HiTuf will not fit into a light fitting.
PVC FTE is not well regarded in OSG re UV protection.
Pyro would be horribly expensive as I lack the tools.
FireTuff is not a flex (solid-core), is silicone (high temp),
and most probably UV rated (re stricter fire code needs).

Would it be better to use white 2-core-w/CPC FireTuff?
It's only about £1 a metre so would only be £1-2 at most.

Thanks.

Right, I read it as you were going to run the flex a reasonable
distance across\up\down a wall to the light from the socket location.

As you were then. ;)

There is no such rule I'm aware of.
It's usually not convenient or appropriate to do so
for a number of reasons, but it's not forbidden.
