80mm hole in bathroom light

[jimmy]

Ok guys. What are your thoughts on this.

My foreman has kicked off about 80mm holes being drilled in the Back of thorn leopard IP rated bathroom fittings.

I've been doing this because they fit nicely over the existing batten holder and then wire from that to the light fitting.

He suggests the ip rating will be effected and I can't see it.

Any options out there guys??

sounds like a right bodge to me. why not remove the batten holder and do the job right?

Wind up??

What about silicon around the hole, that'll fix it,, Ipxxxxx.xxxxx

In all honesty, who cares?!? I cut larger holes (maybe not 80mm ) in the preformed plastic bathroom fittings for two reasons, A: because you cant get three cables through the crappy plastic grommets that are supplied with them, and B: because the crappy plastic grommets are always off center.

We had a job on where we fitted 90 of the buggers throughout communal ways so no need to preserve IP rating there, each one was given a new 30mm hole dead center. That was a good day for the apprentice! Cutting all the holes, prepping all the ballasts

Bodge or no bodge, so long as the IP rating is no affected then who cares? That's what sillicone is for!

If you're asking for opinions to defend your actions, then I think you already know the answer.

That's just given me a great idea for a novelty silicone sealant dispensing gun.

You can't be serious, how can you think an 80mm hole in a sealed fitting wont affect the ip rating, presumably the reason they are being fitted in the first place

100% agree, only a flecking cowboy would leave the existing rose inside the new light. (hopping up and down with anger here)

Well he would be right, the original IP rating is meaningless if you've made an 80mm hole in them. If you'd made the hole less than 50mm it might still be IP11 but at 80mm it's IP00.

As far as options go you need to decide whether the fittings still meet the IP requirements of the UK regulations, if not I guess replacements.

I'm not agreeing with this thread, or condoning the action, but if the hole is drilled at the back if the fitting and the back of the fitting is against the ceiling the ip rating has got to still be above ip00, simply because you couldn't get a 1mm rod in to the fitting

A new take on the wimpy ketchup bottle?

What's the IP rating of a modular fluorescent then? Anyone can shove their finger in one of them!

It doesn't matter if you cut a hole out, so long as you can preserve the IP rating afterwards. By fitting the light flush to the ceiling, the hole could be 1000mm and it would still be only the gap between the fitting and the ceiling that would determine the IP rating.

 

[richy3333]

Surely the fitting gets an IP rating through some sort of assessment etc and that doesn't foresee an 80mm hole, so if you change the fitting like that you loose the rating? Either way doesn't sound clever to me. Sealant fails over time.

Why not keep the flex and wire the light to that through the grommet. Call it an art installation?
