230V fan in Zone 1?

jstephens251 · Dec 11, 2013

Hi all,

1st fixing a barn conversion at the mo

Builder has threw a spanner in the works and says the location of fan will now be in zone 1 near shower.

If it has to be selv then i will wire for a transformer. only snag is i allowed for standard fan and selv fan is a *** load more lol

the OSG says though minimum IPX5 with water jets and i was looking at this unit

XPELAIR DX100BT 100MM AXIAL BATHROOM FAN WITH TIMER. Free delivery! | eBay

what you reckon?

I would say any alteration is chargeable, unless you were told otherwise when pricing for the job?

It's an extra to me

As long as the unit complies with the recommendation of BS7671 then I see no problem with fitting one.

230V ventilation gear is allowable in zone 1 as long as it is at least IP44 and the manufacturers instructions don't state that it isn't suitable for use in zone 1.

Double check your instructions and then carry on as normal.

Can no one read a book these days? It's written in black and white in section 701!

The amount of builders though who claim "you can't do that" or "my spark wouldn't allow that" is unreal....if the regs allow it and it meets the requirements for water ingress protection....whats the problem....

Hi D,
While that is true, a note accompanying that paragraph (GN7) states where the equipment is to be used where water jets are present (in that zone) then they shall have a IP of at least IPX5

Also no one has mentioned where Selv/Pelv fans are concerned the safety supply source shall be fitted outside of the zones.

Well if anyone is going to install a mains fan in a water jet then they're a moron! Lol. The only place where you're going to fit a fan is either on the wall or in the ceiling at a height above the shower head, in which case, IPX4 is all it needs be.

I would like to think anyone with half a ounce of sense knows that anyway, or is that too much to ask????

Would you class a shower head with a removable hose as fixed though?

Yes, because if your intention is to detach it and then point and blast at a piece of electrical equipment then you deserve to be a in a body bag!

Fair enough lol

You can never tell on here Dilb lol (conversation re: 150m spur last night lol)

Here is the page D, you may interpret it differently to me, just I had a similar argument with a builder, I ended up fitting a Selv Fan lol
