A junction box upon inspection offers points of entry for lighting and electrical cable, so its very important to have the correct junction box for the application. These points of entry consist of a knockout, integrated thread or self-sealing membranes.

Internally there are mounting points for screws in each corner, use the correct masonry plugs, anchors and fixings for the surface you are mounting to. Once the junction box has been mounted and all cables prepared, wire connections can be made using the correct cable terminals and splices. A sealed box lid or box cover then provides security for all the internal components.

What materials are they made from?

Junction boxes are made from various materials such as; ABS, Aluminium, Carbon Steel, Duro-plastic, Galvanised Steel, Glass Fibre Reinforced PET, GRP, Mild Steel, Nickel-Plated Steel, Plastic, Polyamide, Polybutylene Terephthalate, Polycarbonate, Polyester, Polypropylene, Polystyrene, PVC, Stainless Steel, Steel and Thermoplastic.
