What would cause a power wire to melt?
What would cause a power wire to melt? A coil of wire, such as an extension lead, increases the magnetic electrical field current. The result is the production of heat. The wire then gets hotter, making the outer plastic coating soft (and therefore weaker), which strengthens the electrical field, eventually causing the coating to melt. What kind of wire is used to start a gas engine? You'll normally find 0-gauge and 1-gauge wire used to wire the starters of high-compression gas and diesel engines. More commonly, you'll find starters and batteries wired with 4-gauge and 6-gauge cables; and sometimes 8-gauge...
