Hi, 

The regs stipulate zones for bathrooms, however I need some guidance on bathroom cupboards.

I have completed an inspection where there is heating control equipment located inside of the bathroom cupboard. This is mounted inside of an IP rated enclosure with a sealed transparent hinged door. There are no metallic parts, no switches etc, just the digital interface for the product itself. 

There is also a network switch, mounted inside of a locked rack enclosure. 
 

Am I right in thinking this is OK and I can treat this as a separate location? 

There are no sockets or switches on show - only 13amp unswitched fused connections. 
 

Thanks.
