SELV - Not a fan of?

whjohnson
Short question - is a mains voltage extractor fan permissible in zone 1 or 2 in a bathroom provided it is protected by a 30ma rcd and that all IP requirements are met??

OSG chapter 8, Table 8.1, page 94 says only 25vAC or 60v ripple-free DC SELV or PELV, yet I have just been to the wholesalers to look at what they have, and they showed me two mains fans with "Suitable for" or "Complies with" Zone 1 emblazoned on the packaging.


I am looking to fit a fan with a humidistat but am struggling to find a SELV version if that is actually required.

So, which is correct? The manufacturer (whose instructions must be followed) or the on site guide, whose instructions must also be followed!


Comments welcome.

    My OSG is the 18th ed. I reckon I'll go the SELV route to be on the safe side - it is nearly 3 times more expensive but at 60 years of age I want to coast safely to retirement and not have to stand in front of a man with a white wig simply because the wiring regs have become too woolly to follow these days!
