Regulations for electrical installation in bathrooms
The following is a guide to help you understand which accessories can be placed in a bathroom. This is not an installa-
tion guide and any doubt should be made to the EIA Regulations in the lighting or a qualified electrician.
First of all, it is important to understand the position for which the lights are classified in a bathroom. Theacronym IP
stands for "Index of Protection" and is always followed by two characters. These two numbers refer to the level of pro-
tection and it is important that you choose accessories with the correct protection, depending on where you want them
to be located within the bathroom.
The diagram shows a bathroom split into four clear areas: 0.1, 2 and 3.
Zone 0 is inside the tub or the shower itself. Any product used in this area must be low voltage, (max 12v) and be rated
at least IP67 which is total immersion proof.
Zone 1 is the area above the bath or shower at a height of 2.25m from the floor. In this area is require an index of mi-
nimum protection of IP44. If the product is a voltage of 240V the circuit must be separate and protected by a residual
current device of the 30ma.
Zone 2 is 0.6m out from the ground to a height of 2.25m, and above the zone 1 to 0.75m and the zone result of placing
a semi-circle of 0.60m over the basin, starting from the point of exit water. In this area, the rate must be at least IP44
protection.
Zone 3 is anuwhere which is outside any of the above areas 0,1 and 2 (subject to specific limits) and where there is no
use of any water motor. This area requires a rate of IP-X1.
In addition to the above, if there was a chance to install a product near a water intake, regardless of the situation in
areas 1.2 and 3, it should be at least an index of protection IP65.
If necessary, this information can be found in detail in the IEE regulations for lighting.
