The particular requirements of this part of IEC 60364 apply to electrical installations in indoor or outdoor locations where a bath tub and/or a shower is intended to be permanently placed in a specific location.
The extent of the location containing a bath tub and/or a shower is limited by:
- the lowest finished floor level;
- a horizontal plane 3 m above the lowest finished floor level;
- a vertical circumscribing virtual surface at a distance of 4 m from the fixed water outlet for the bath tub or shower; and
- the volume within the walls, floor and ceiling that border the location containing a bath or shower, measured to a depth of 6 cm.
NOTE 1 Where the shower head and flexible hose are detachable, the fixed water outlet is taken to be at the supply end of the flexible hose.
The requirements of this document also apply to fixed electrical installations in mobile applications, for example caravans, mobile homes, shower containers. This document does not apply to emergency facilities, for example emergency showers used in industrial areas or laboratories.
NOTE 2 For locations containing a bath or shower for medical treatment, special requirements can be necessary.
NOTE 3 For prefabricated bath and/or shower units, see also IEC 60335-2-105.
