fitting gu 10 fittings in to kingspan

[marty1234]

hi whats youre thoughts on fitting gu 10 fittings in to kingspan
the fittings are not fire rated but the kingspan has been cut away about 200mm round the fitting

 

[telectrix]

have you got some clearance above? if so, should be OK. or fit LEDs.

 

[i=p/u]

most ive installed says 100mm clearance all round

Check the installation instructions for the fittings. Most will give a minimum distance from insulating material. As a minimum I would expect 4inch.

can you buy boxes of some sort to keep insulation away from fittings, i see theres is ones which are priced at £11 each, do you guys know of anything else available...? thankss

 

[Darkwood]

you can buy fire rated gu10 fitting for less than a tenner so it will be cheapest safest way to change your fittings

but even fire rated fittings need to dissipate the heat generated. a good 6" all round and above clear of crap is my recommendation.

Dont often see you pass on poor advice telectrix, if you cant get the clearance given in the instructions then the fittings shouldnt be installed opting to fit them and use LEDs that dont generate alot of heat will get around this but what if the customer later decides they arn't bright enough or they move or rent out etc there will always be a possibility a standard gu10 lamp may be fitted which then would pose a fire risk.

Yes agree i re-read post i misread it originally, if he has access i find chicken wire excellent to keep at bay the insulation and stops other trades knocking it onto the fittings.

sorry there, but if somebody wants to change the lamps, they should know what they're doing. a bit like fitting 10 400watt chandeliers to replace single lamp fittings on a 1.5mm circuit.

.......not sure that helps the problem, fire rated only refers to spread of fire upwards through fitting, not as a result of a fire from the fitting, which will get as hot as the next. Or so I am led to believe. The 'can' does not mean it's fireproof....?

In the example you've given putting 4kw on the lighting circuit will if all is correct just trip the mcb though overload and wont really pose a danger, if the gu10 fitting is installed against its guidelines thus relying on led lamps so little heat is generated just to stay safe then i believe this is wrong, homeowners buy lamps that will fit a particular fitting so its imperitive that doing so dosnt pose a danger whichever lamp is chosen and in the above therectical example it would be a fire risk if the fitting didnt have the clearance it required, just because marty1234 may know to use LEDs he may not be there the next time the lamps are replaced neither may the present occupant. It is the responsibility of the installer to follow the instructions fully then no matter what lamp is ever used in the fitting it will be safe, if the installation safety instructions cannot be met then it shouldnt be installed whether or not the intention is to use LEDs.

Yes i already been pulled for this reply, i mis-interpreted the post cos i read it quickly but thx for the correction.

OK . i'll concede the point. however, even if using LEDs, i would ensure there was a minimum clearance. all becomes acedemic though when we fit according to best practice, then along comes the loft insulation company and packs 12" of fibreglass all around, over and tucked in nice and cozy, then building inspector passes the job.!!!
