Hi,
Buying a replacement extractor fan. It falls into zone one with the room setup. Looking at two fans. One is rated zone 1 one is rated zone 2 and both have ipx4 ratings from what I can see and from wider reading ipx4 is the requirement for zone one and two?

is the ipx rating all the appliance rating is based on? For 10 quid extra it doesn't matter but it piqued my interest.

TIA

The way I read it ...701.55 Current Using Equipment:
States that " In Zone 1 only the following fixed and permenantly connected current-using equipment [ which includes ventilation equipment] shall be installed, provide it is suitable for installation in Zone 1 according to the manufacturer's instructions."
So it's not just the IP rating, it's whether the manufacturers instructions states it is suitable for Zone 1

Thanks for your thoughts on it. It seems weirdly vague to have some rules like the ipx4 with the addendum of on the proviso it's backed up by a 30ma RCD for zone 1. Then rely on manufacturers ratings too.
