Equipment in bathroom cupboard

vantech

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.

    Of course if the charger had been fed via a U.K. double wound isolating transformer from a shaver outlet the deaths may not have happened. Or would they?

    I suspect a separated circuit wouldn't have helped in Graham's example - the shock current flowed from L via the water and victim to N - no path to Earth involved. A 230V separated circuit (like from an isolated shaver transformer) would have been able to supply such a shock current just the same.

    Perhaps a safer policy would be 30mA RCDs plus making all equipment deliberately class 1 with earthed parts around the live conductors (even if those live parts aren't exposed to touch) - so making a L-N shock without a L-PE residual current less likely.
