Depending on the finish of your garage, the internal wiring may be open or closed. Open wiring on brick, concrete, cinder block or plastered walls can be carried out with light cables, flat wires and unarmored wires.

1
The cross section of the wires is calculated based on the estimated wiring load. We recommend using a copper wire. Horizontal wiring is conducted on top, the distance to the wiring from the ceiling down is 15 - 20 cm, descents to switches and sockets are carried out vertically.

The wires are fixed with tin jumpers 10 cm wide, attaching them with dowels to the wall. Junction boxes, sockets, switches are mounted in the same way. Currently, stores sell special channels for electrical wiring made of plastic. You can use them.

Most often, hidden wiring is done in garages, it is better to perform it before plastering.
For switches, sockets, distribution boxes, it is necessary to drill recesses so that their upper edges are flush with the plaster. If the walls are plastered, it is necessary to cut through the grooves and lay the wires in them, cut through the recesses for switches, sockets, junction boxes.

Wires for open and flush mounting are different. They will tell you about this in a specialized store and recommend what suits you.
