USB charger outlet in Bathroom Zone2

Peter69

I've been asked to add a USB charging port into a bedroom with a bath in it.

My understanding of BS7671 is that a room with a bath is a bathroom. As such the outlet would be in zone 2 of the bath.

Would I need to power the charger via a safety transformer and could this be built into a +IP4 enclosure similar to a shaver outlet

Thanks for your assistance

    I disagree ... sub-assemblies aren't certified to suitable product standards.

    Legislation also gets in the way for that type of 'assembly', including the EMC Regulations 2016.

    This definitely falls into what is being covered by Regulation 113.1.

    Perhaps a hard wired cable that cant reach the bath?

    Not sure if a waterproof usb fly lead exists though?

    You need to be really prepared to carry a male to female long lead. 

    I am working on a reduced output voltage USB supplied by a isolated psu that has its output limited either 230vac or 12-24vdc selv. So even a fault condition the psu will fall over rather supply more volts or amps.

    Bath bombs and damaged skin submerged in a bath is my fear.

    My intention is selv or isolated psu outside this area.

    As previously discussed USBs can be selv but this isnt enough for safety purposes whilst charging in a bath.

    Interesting thought! Rather like a tethered lead on an EVCP.

    Now that USB-C is the common standard (link), a plug on a lead could be quite useful. Being a plug, its use would not be prohibited. How daft!
