?Technical Info Bathroom and shower lighting Information on zones and IP ratings: Bathrooms are considered to be a  special location for electrical installations because they have an increased risk of electric shock for the users, due to the proximity of water and the low electrical resis- tance of the human body. Electrical contractors make bath- room installations as safe as pos- sible with careful adherence to wi- ring and building regulations and a wise choice of equipment. A bathroom can be divided into zones which take into account windows, doors, walls ceilings and partitions and is based on a per- ceived level of risk zone. Each zone has specific requirements regar- ding the electrical equipment that can be used in that zone. Zone 0 // The interior of the bath- tub or shower basin. Zone 1 // The area around the bathtub or shower basin up to a height of 2,25m above the floor and at a radius of 1,2m from the water outlet. Zone 2 // Is limited by the vertical planes external to zone 1 and par- allel vertical plane (s) 0,60m exter- nal to zone 1. Zone 3 // Is limited to the vertical plane(s) external to zone 2 and the parallel vertical plane(s) 2,40m ex- ternal to zone 2. A Zone 2 Zone 3 0,6 m 2,4 m Zone 1 Zone 0 Zone 2 Zone 3 0,6 m 2,4 m Zone 1 Zone 0 0,6 m 2,4 m 0,6 m 2,4m 2,25 m (A < 0,15m) 2,25 m (A > 0,15m) 2,25 m (A < 0,15m) 2,25 m (A > 0,15m) Electrical equipment used in bathrooms must not be ad- versely influenced by envi- ronmental factors. These can include condensation, humi- dity, steam, drops of water or sprays from showers. There are a number of different indicators relating to electrical products that identify the products safe- ty and suitability for bathroom use: 1 // IP Ratings Bathroom electrical equipment must carry an appropriate Ingress Protection (IP) rating for its loca- tion. 2 // PELV and SELV Equipment may also be described as a Protective Extra-Low Voltage (PELV) or Safety Extra-Low Voltage (SELV) product. PELV products use low voltage but are connected to earth. SELV products are again of low voltage, but the voltage supply output is double insulated from the input. This enables a SELV product to be used in any zone in the bath- room providing the source (e.g. transformer) is housed in Zone 3. Lighting Electrical contractors are required to look for an appropriate IP rated product (recommended IPX4 or above). Some types of lights can be in- stalled in Zone 0 (specifically for use in shower enclosures) but they must be 12V SELV.
