Safe zones for electric cables

Electric cables are usually run in prescribed safe zones. Knowing where these zones are allows you to correctly install cables and help eliminated damage to them when drilling walls at a later date

The safe zones for cables concealed in walls are

• a horizontal zone within 150mm of the top of a wall

• a vertical zone within 150mm of the angle formed by two walls

• the horizontal and vertical zone to an electrical accessory

• where an accessory on the reverse side of the wall can be easily determined eg through a door or archway and the wall or partition depth is 100mm or less then the horizontal and vertical zones to that accessory apply to both rooms.
