USB charger outlet in Bathroom Zone2

Wow. So much great information here guys.

If I've understood  correctly 

1. It is possible to have a USB in Zone 2.

2. It must be IPX4 rated (im not sure how to protect the pins)

3. The output must be SELV 

4. The converter must be outside zone 2 and hard wired.

5. It must be on a 30rcd 

6. It must have limited energy ie 20va (3.1A/ 5v) {base on shaver socket energy}

From the safety risk, these may less then what is allowed, but due to the potential of a submerged body in fresh water and the higher PD voltages and current that those pose a risk.

At present, im not sure if the idea is to use the USB in a bath but it is a foreseeable risk when the socket is so close to the bath. 

It is a shame that 12v or even 24v  wouldn't be used but reading between the lines, thes voltages could increase risks.

I presume there are no restrictions  once outside zone 2 but  not the full 3m away from zone 1?

Thanks for all the comments

It's 2.5m these days rather than 3m, but yes the limitation is on all sockets except SELV or isolated shaver types. 701 specific requirements for the room/location outside zone would still potentially apply (e.g. connected to supplementary bonding system if there is one, if the output was PELV for instance, RCD additional protection etc.)
