80mm hole in bathroom light

Regardless of what happens to the IP rating, the foreman may not always be right, but he IS always the foreman!!!

I still remember stepping out our front door to go to my very first day at work many years ago. My Father said to me: "Remember to do exactly as you're told no matter how stupid you think it is as long as it's not dangerous and if you do think it is dangerous, ask them to put their instructions in writing and sign it".

you forgot to mention that your mum had put your sarnies in the gas mask bag. :icon10:

Lol , I had one , then I graduated to a haversack. Wasn't IP rated though .:drunk:

There are literally hundreds of properties in South Somerset with bathroom fittings installed in this way and I personally have fitted many like this..We had a meeting with foremen about it on one big contract and the upshot was that IP wasnt compromised if the base of the fitting was caulked up to ceiling. In effect the base of the battenholder is just a joint and at least it is fixed unlike floating connectors inside the fitting which are needed if the point is 3 plated..just my two pennoth

I would +1 on this being fine, in fact quite a neat job if done correctly, it preserves the loop-in base on a 3 plate sytem, saves extending cables to go into crappy luminaire connectors or even worse floating connectors and as long as the hole is sealed around with silicone etc. it preserves ip rating.
I have seen 100's on I&T and wouldn't evenn think of coding it.
Use common sense not manufacturers garbage.

I agree. A waste of time debating something so inconsiquential.

 

[Andy78]

What about the existing rose base being sat behind the gear tray of the new fitting, the cables absorbing all that lovely heat with no HR sleeve on ? The cable entries are offset for a reason in 2D fittings.
This is a right mickey mouse way of carrying on and serves no purpose except pandering to laziness.

 

[grumpyjohn01]

nonsense Andy! I have been back to I&T properties done like this some years on...obviously common sense says you drill the hole away from the hot bit of the gear and use heat resisting flex cores to make the base to luminaire connection..at the end of the day if its 3 plated you will have to make a joint or joints anyway, why not do it this way as Somerset says can be very neat if done well and thats without even considering crappy grommets etc supplied with fittings these days..

 

[Andy78]

Not something I would do myself though.
I have seen enough 2D fittings with internal scorching and crumbling plastic fittings due to heat to tell me its not a good idea.

Actually, you're right - she did!!

I got myself an ex-RAF haversack a bit later on because there was more room in it for my overalls & flask of coffee as well as the bait tin.

I used the same haversack to carry all my books & thing in when I went to Technical College on Day Release one day a week too. (Mechanical Engineering courses they were)

 

[somersetsparks]

I think the key point is that its a 2d fitting on the ceiling of a domestic bathroom which is replacing a battenholder, it is quite likely to be outside of zones anyways.
Another key point being that if the gaffer says it just do what they say, unless they are asking you to break the regs.

First post and a million replies..... Don't you guys do any work

The fitting is an led, not a 2D and I used to think it was a bodge job as I've fitted thousands of these but noticed more problems using connectors and a small entry hole.

With 3 or 4 cables in there and then a fan 3 core the room isn't good and I've seen loose connections from people trying to squash all the cables in there.

Never seen a problem with leavening the Barton holder base on there with fly leads out. Neat job and can't see IP rating being 00.

Maybe I'll email the manufacturer.


Cheers for your thoughts guys.
Interesting reading.

Some of us are retired and have become Gentlemen of Leisure. The rest are too busy arguing among themselves about what size cable to use for showers and cookers and how to earth bond a plastic pipe to do any actual work, and being a rather well-endowed Geordie bloke I can tell you that small entry holes have been the bane of my life!!!

No need. They will tell you that any alteration to their product that isn't described in the instructions will invalidate their warranty. No matter how well it is bodged up, I mean sealed, afterwards.

Yer melted connectors dripping down the side of the choke and a birds nest of cables all wedged through a 20mm hole does make a job look more professional

 

[telectrix]

20mm? a lot of these fittings, you'll be lucky to get a 16mm hole
