    For locations containing a bath or shower for medical treatment, the power socket is special requirements may be necessary and protected by an RCD with a rating not exceeding 10 mA and seprately the earthing point from main earth, this is to avoid the leakage current from other equipment via this point to earth.

    The particular requirements of this part of IEC 60364 apply to the electrical installations in locations containing a fixed bath (bath tub) or shower and to the surrounding zones as described in this standard.

    OR

    16th Edition IEE Regulations

    Bath and shower room requirements (amended)

    The revised Regulations for bath and shower rooms are based on the dimensions of four zones into which the space is divided.

    Zone O.

    is the interior of the bathtub or the shower basin. In those cases where a shower has no basin, the zone extends 50mm above the floor and includes the volume within the vertical surface at a radius of 1.2m from the water outlet position of a demountable shower head, or at a radius of 0.6m from the position of a fixed shower head.

    Zone 1.

    extends from Zone 0 up to 2.25m above the floor, and outwards to the extent of the bath or basin, or the extent of Zone 0 as defined above where there is no shower basin. It includes the space below a bath or shower tub or basin where that space is accessible without the use of a tool.

    Zone 2.

    extends outside Zone 1 for 0.6m horizontally and up to a height of 2.25m. If the ceiling height is more than 2.25m, the space above Zone 1 up to 3m is also zone 2

    Zone 3.

    extends outside Zone 2 for 2.4m horizontally and up to a height of 2.25m. If the ceiling height is more than 2.25m, the space above Zone 2 up to 3 m is also Zone 3

    If the space under a bathtub or shower basin can only be accessed with the use of a tool, that space is outside the zones. If no tool is required the space is Zone 1.

    The extent of the zones is shown in Figs 7.1b) to 7.1g) in diagrams which are not to scale.

    Switch and control gear is permitted in any zone if such gear is incorporated in the equipment installed there, which is suitable for use in that zone. No other switch or control gear is permitted in Zone 0. In Zone 1, only switch and control gear for SELV may be installed, but the safety source for the system must be installed outside Zones 0, 1 and 2. In Zones 2 and 3 or outside the zones but within the bath or shower room, switches and socket outlets are permitted providing that they are fed from an SELV source installed outside Zones 0, 1 and 2. The exception to this is the socket outlet on a shaver supply unit that complies with BS EN 60742, Chapter 2, Section 1, which may be installed in Zones 2 and 3. Insulated operating cords of pull switches are permitted in Zones 1, 2 and 3 but they must comply with BS 3676. All equipment installed in Zone 3 must be protected by an RCD with a rating not exceeding 10 mA.

    Electrical equipment installed in a room containing a bath or shower must have protection against the ingress of water as follows:-

    in Zone 0, only equipment which is intended for that situation, water protected to IPX7 or

    in Zones 1 and 2, IPX4 or

    which is protection from splashing. Where water jets may be used for cleaning, such as in public bath and shower facilities, IPX5 or applies, which gives protection against water jets.

    in Zone 3, IPX5 or must again be used if cleaning by water jets is likely. See (Table 2.4.), for details of the index of protection (IP) system.
