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.

    230V ventilation equipment is permitted in zone 1 if the manufacturer says its suitable in their instructions (reg 701.55) (plus all the usual requirements for IP rating, 30mA RCDs, supplementary bonding etc apply)


    Earlier regs did differ on the requirements though - it might be your OSG is out of date? (or a latest copy has out of date information?)
