Electrical wiring of timber mass homes

Our granny flats and backyard cabins come with a number of vertically pre-drilled channels in the walls for electricity wiring. The channels are going all the way from the top to the bottom boards. This creates a chase through which wires can be run within the solid timber walls. The electricity channels are marked ‘El.’ on the floor plan drawings of the kit supplied by YZY Kit Homes.

Important note: Before construction of the building begins, there are 2 important steps to note relating to electrical wiring. Step 6 – Pre-drilling holes for electricity and hold-down rods and Step 7 – Marking holes for electricity wires for an electrician to easily locate the channels and wire the building.

Wall plugs, switches, wall lights

Wiring for wall plugs, switches and lights is often run below the floor level and brought up through the pre-drilled channels. Wires can be snaked through the walls either during or after construction. An electrician cuts the holes with Hole saw in the location of all outlets, switches and fixtures at any height required of the pre-drilled vertical electrical channels as illustrated in the below image.

Wiring ceiling light fixtures

Ceiling fans, lights and smoke alarm detectors are wired form the top. As prefabricated building is quick to build with every part pre-cut, it is quote easy to get carried away with the installation. Make sure to wire the electrical before roof insulation and the roofing is complete.

Important note: keep in mind that rough wiring your YZY Kit Home during the construction is subject to the same rules as other wiring work. This means the job should be performed by a licensed electrician and inspected by a local building code official.
