Siting Of Pull Cord Bathroom Extractor Fan

New build extension with a shower room.
Builders have sited the shower extractor fan directly into the external wall above the shower cubicle
The pull chord will hang into the shower itself and is positioned 2.5 meters above shower tray.
Builder has said this is safe as it will be surrounded by tiles with no exposed electrical cabling but as an "oldie" I though fans had to be sited away from water as you risk getting shocked if they get wet.
Need to know answers asap as external wall is due to be rendered soon

Hi Mark,
I think you will find that the siting has to do with the IP (Immersion Protection) rating of the appliance.
have a look at http://diydata.com/electrics/ip-classif ... ations.php

The pull cord will be mains electric and it would appear that it is OK at 2.5 m above the shower tray. However, if the fan is below 2.25 m above then it will need to be PELV or SELV
