Is aluminum wiring banned by the NEC?« Back to Questions List

Although aluminum wiring is not banned by the NEC, it is discouraged by most professional electricians. When aluminum wiring first came about in the 1960s, a 1350 series aluminum alloy was used in most homes since it is cheaper and lighter. Years later, however, it was discovered that this material was prone to overheating and electrical fire hazards. Today, the NEC approves AA-8000 series aluminum. Although this material is more reliable, it is still not approved by city electrical safety standards for electrical work and will void many home insurance policies in the case of an electrical fire.
