There are a few guidelines to be followed when chasing cables or pipes into walls.
Chasing walls for electrical cable.
Chasing cables and pipes into walls.
Cables that are not in electrical cables safety zones.
Electrical wire and cable must be sized and installed correctly to pass an electrical inspection and keep electricity running safely through your home.
If it isn t possible to chase the walls to that depth then the cables should be set deep enough so that metal capping can cover them and allow for plaster to cover that.
Such cables must also be protected by a 30ma rcd.
In electrical chase the channels of around 50 to 100 mm width and 50 to 75mm depth are carved in the masonry or concrete elements to place the electrical conduit and other services of house and conceal them in the walls for better aesthetics.
It is allowed so long as the following guidelines are followed.
Chasing is a continuous recess within the floor ceiling and walls for the required pipe work and conduit.
This guide will teach you the difference between types of electrical wires and types of electrical cables.
Electrical cable safety zones for partition walls less then 100mm can occur on both sides of the wall.
When running cables or pipes up or along a masonry wall the neatest method is to bury or in builders terms chase them in the wall surface.
The cable must be over 50mm below the surface.
There are guidelines to follow to make the installation of electrical cables as safe as possible for you and anyone else entering your home.
Choose between a fixed chassis or a plunge chassis for more control.
Tracing electrical wiring can be tricky and involved.
You can also buy circuit and wire tracers made specifically for the purpose of locating electrical wiring behind walls and underground.
Wall chasers are available in 110v and 230v and have adjustable depth of cut for accuracy.
All electrical cables should be set into the walls at a minimum depth of 50mm if they are not mechanically protected.
Sometimes it is not possible to run cables in these zones.
It is as well to note at this point that if you are chasing walls for the installation of a new circuit that this work may be covered by part p of the building regulations see our project for more info.
