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.

    There is NO ‘residual current’. The OCPD will operate, but it is likely the person in the bath will be seriously injured or killed before that happens, as the electricity tracks through salt straight to the person's trunk, as it's the most conductive thing in the water, to get from Line to Neutral.

    As I said, no protective conductor, no alternative path other than L-N, so an RCD is wholly ineffective. This is not a theory … it was proven in an investigation after two children died in a bath in Germany after a shaver on charge from the mains fell into the water and killed them both.

    I am struggling with this. We have in the bath water a couple of electrodes. The bather is in contact with neither of them. How can the bather be a lower resistance between them than the bath water?
