Electrical Materials: Wires, Cables and Building Supplies
Electrical construction materials can include wires, cables, conduits, switches, protection devices and installation accessories. The design, load and installation environment determine which specifications are suitable. Use a qualified electrical professional and approved project documents when selecting products.
Verify electrical product ratings and certification
Check conductor material and size, insulation type, voltage and temperature ratings, length or pack unit, manufacturer and required certification. Confirm compatibility among cables, conduits, switches and protection devices. Do not choose wire size or protective equipment based on price alone; the electrical designer must specify these for the intended load and installation. Compare exact model numbers and ask whether the quote includes all accessories, taxes, transport and installation-related items.
