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

    Does it really have to be <600mm from the bath?

    Zone 2 demands IP X4 (701.512.2) - and I don't see any USB socket complying with that (there's an exemption for shaver sockets, but not as far as I can see for other kinds of sockets, SELV or otherwise).

    To be quite frank, splashing aside, the distance doesn't appear to matter for using devices on charge in the bath, because extra-long leads are quite commonly available.

    I guess there are a number of factors to consider - water getting into the socket contacts themselves and causing problem (either directly or by causing corrosion, which can leave conductive deposits where insulation is needed), water getting into the "conversion unit" with the risk of bridging the mains side to the USB side (in additional to the usual damage) and then there's water ingress to whatever device is connected to socket. Mind you most of those devices contain batteries so the problem doesn't necessarily go away entirely with the removal of the socket..

    I have found USB C IPX4 connectors that I can fit ti a plate or grid. I'd just have to make the plate to the same standard.

    I've been pondering that....  presumably a type with a cover of some kind - so the IP rating is only maintained when the socket isn't in use? (or possibly requires a matching IP rated plug, which users are unlikely to use).

    Shouldn't we interpreting 701.512.2 as requiring the IP rating to be maintained at all material times - not just when it's not in use?
