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.
