100FT Aluminum Ground Wire Product Dimensions: 2 pounds Shipping Weight: 2 pounds Model: 41070 Item Package Quantity: 1 cable type: Antenna cable left connector type: Bare wire right connector type: Bare wire Length: 100 feet Warranty: Limited lifetime warranty Use 8AWG solid bare aluminum ground wire for satellite, antenna and cable television installations. This wire is soft and pliable and can be formed easily to conform to the shape of the house siding. Use ground wire to connect ground blocks, splitters and multi-switches to ground clamps, ground rods and split bolts. Aluminum wiring is still permitted and used for certain applications, including residential service entrance wiring and single-purpose higher amperage circuits such as 240V air conditioning or electric range circuits. The fire risk from single purpose circuits is much less than for branch circuits. But it's not necessarily because of a "new alloy" as some folks assert. It's because there are enormously fewer connections (four or six rather than 30 or 40 per circuit) and thus statistically a smaller chance of a connection failure. These connections do still burn up, as indicated by field reports.

Aluminum 1100 Wire - 1/16" OD Annealed, 32 Foot Length, 1LB Spool Part Number AWC-116-30 Material Type Aluminum 1100 System of Measurement English Outside Diameter 1/16 inches Overall Length 32 feet Specification Met ASTM A313 Aluminum wiring, used in some homes from the mid 1960's to the early 1970's, is a potential fire hazard. How safe is aluminum wiring? According to the U.S. Consumer Product Safety Commission, fires and even deaths have been reported to have been caused by this hazard. Problems due to expansion, or more likely micro-fretting and arcing at the connectors, can cause overheating at connections between the wire and devices (switches and outlets) or at splices. The connections can become hot enough to start a fire without ever tripping a circuit breaker! CPSC research shows that "homes wired with aluminum wire manufactured before 1972 are 55 times more likely to have one or more connections reach "Fire Hazard Conditions" than are homes wired with copper. "Post 1972" aluminum wire is also a concern. Introduction of the aluminum wire "alloys" in 1972 time frame did not solve most of the connection failure problems. The heat has deteriorated the insulation on both the connector and the wires. A portion of the connector's spring (white overheated section of spring in photo) becomes red hot at current above 12 amps.
