<br>writeablog.net Copper is favored for its glorious conductivity and durability compared to aluminum counterparts, making it splendid for prime-load functions. Copper conductors supply several benefits over other materials like aluminum. MC cable, or Metal Clad cable, is a type of electrical cable that consists of insulated conductors encased in a metallic sheath. The designation "4/3" refers to the quantity and size of conductors inside the cable. Specifically, a 4/3 copper MC cable contains 4 conductors-three for carrying current (every usually sized at 3 AWG) and one ground wire. AC systems all the time use overhead wires, DC can use either an overhead wire or a 3rd rail
