Fitting an LED Spot into a loft hatch?

thisisthecount · Oct 13, 2023

I'm looking to consider asking my electrician to fit one extra LED flush-fit spot in loft hatch so it matches the rows in the ceiling to a total of 9 (3 rows of 3). He's concerned that it won't be safe and I totally get this, but is there a way to install this with some form of strong, flexible 3-core cabling or technique? Just so when we use the hatch, its not going to cause issues?

It’s possible.

A bit of flexi conduit should protect it… but it might be in the way when climbing the ladder.

What sort of downlights are they?

Some come with a separate driver that could sit in the roof space, and extend the ELV wire to the light.

well when it closes, its 100% flush with the ceiling and is the exact same paint finish with minimal trim. It will line up perfectly with the middle row. Is there any safe way of doing this? They are very very slim these spots, 30mm. THey don't have drivers, just on their own and one continuous loop.

these are the spots:

It's not some I'd do, but it's possible as above.

Can't you arrange the downlights so that you don't need one there?

bit late now, all drilled out and ready.... ;-(

If it’s the ones hanging out the ceiling, then they seem very low profile… shouldn’t be a problem even with the ladder

If those are the final connections to those lights then the block connectors need enclosing and the cpcs correctly terminating.

Incredible that this needs to be related to an electrician through their customer - especially given how easily conductors slip out of those cheap push fit connectors.

A flex from a suitable JB to the light will be fine, I'd probably fit a bit of ply or something behind the light to prevent it getting kicked when the ladder is used.

Also coming here and pretending that this is the work of an electrician is just daft, we can all see that those connections are not the work of any qualified person.

We’ve had the same issue..!!!!

Firstly, ensure the circuit is RCD/O protected.

Secondly, we fitted a small ‘metal’ cage enclosure over the gubbins if the D/L showing between the loft steps.

Thirdly, we installed a double pole ‘Cabinet type Sw’ that isolated that individual DL when the Loft Lid was lowered.
(This was a FIXED loft access, not a floating loft lid).

The main issue however, WAS.!!! even though the power was ISO when the hatch was deployed and the cage was protecting the installation…. It proved a hazard when using the Loft Hatch Stairs…!!!!

We fed it with SY 1.5 3c…..

We returned 2 months later, to do more work, and on the request of the client, ended up fitting LED trip to ALL loft steps under edges , BUT EITHER side of the Hazard if the DL cage unit.

They’ve been happy and problem/ incident free,!!!!

ENSURE YOU MAKE A COMMENT on your Electrical Cert, regards possible Access, due to install, and additions to over come the issue.!

You fed a downlight with sy? How did you terminate it?

Thanks this is all very useful and has helped me considerably

There are quite a few hinges which transfer the power supply, so maybe use on the loft hatch.
This is just one example of many, and some are from very reputable manufacturers.

Whisk / stuffers / bandgo / wago.

As the loft hatch is moveable it requires more than just T&E.

I would prefer flex in a domestic environment rather than sy which requires a proper brass gland to terminate and cores need sleeved. Using flex negates the need for both of these. The braid is utterly useless in this situation also.

Not SY though surely. HO7 or pvc flex?

Of all flexible cords that come to mind SY must be the least flexible.

Hi nicebutdim,
Please don’t use CHEAP push fit connectors.!
FLEX doesn’t connect well with Push Fit connectors ( hence why we use Feral's ).
Lever operated Wago may perform better.
But Feral crimping is more acceptable.

You do realise there are push fit connectors that work with stranded cable right?

I'm sure nicebutdim does.

CAPS AND !!!! over the top punctuation here !!!!!

SY gave the required mechanical protection of the movement from the loft hatch.!

20/25mm conduit wasn’t suitable in the space available.

Flex didn’t meet the mechanical movement of the operation of the loft access being operated over and over again. Also the fact that clumpy feet using the loaf steps made me want to possibly over engineer the requirement. Safety first.

Never wishing to offend, just to help.
But you did mention cheap push fits.

APOLOGISES.

I'm not sure I did. But fair enough.

No it doesn't, SY is mechanically not very good at all. And for that apllication you need good flexibility which SY doesn't have.

Yes it does, it's flexible cable, the clue is in the name!

A decent rubber flex is far more suitable than SY, with the advantage that rubber flex will actually comply with UK product standards.
