Chasing Walls For Electrical Cable

Tracing electrical wiring can be tricky and involved.

Chasing walls for electrical cable.

Chasing is a continuous recess within the floor ceiling and walls for the required pipe work and conduit. You can also buy circuit and wire tracers made specifically for the purpose of locating electrical wiring behind walls and underground. 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. Choose between a fixed chassis or a plunge chassis for more control.

Check the whole wall cavity with a stud finder. A decent stud finder is a must have for every wire fishing job but don t throw it back in your pouch after you ve located the studs. 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. Run electrical cable through walls and across ceilings without tearing them apart by fishing wire.

Such cables must also be protected by a 30ma rcd. Electrical cable safety zones for partition walls less then 100mm can occur on both sides of the wall. 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. There are a few guidelines to be followed when chasing cables or pipes into walls.

The cable must be over 50mm below the surface. It is allowed so long as the following guidelines are followed. Wall chasers are a twin bladed power tool used for cutting narrow channels into brick stone or concrete walls perfect for electricians and plumbers. 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.

There are guidelines to follow to make the installation of electrical cables as safe as possible for you and anyone else entering your home. These tools tend to be expensive though making them most suitable for professionals and people who plan to do lots of wiring work. Wall chasers are available in 110v and 230v and have adjustable depth of cut for accuracy. Cables that are not in electrical cables safety zones.
