Copper wiring has several advantages, including:

Why Copper Wiring is Preferred over AluminumД¬opper conductors are popular among electricians and homeowners alike for branch circuits. Copper doesnвЂ™t rust and is unaffected by oxidation. Even though copper is acknowledged to be a superior conductor, it is still cheaper, lighter, and more flexible than aluminum.ДЇor copper wiring, youвЂ™ll need a #4 AWG copper wire that is commonly used for electrical wiring since it is more heat resistant than aluminum. At the connection terminals, copper-clad aluminum does not need an antioxidant layer.ДЄluminum wiring appeals to many since it is less expensive, lighter, and more flexible than copper. To resist corrosion, the connection terminals of aluminum wiring require an antioxidant coating. YouвЂ™ll need a #2 gauge wire for both aluminum and copper-clad aluminum wire. Many licensed electricians use #2 copper-clad or aluminum wire size.В Because it has a lower conductivity than copper, aluminum wiring requires a larger diameter wire.

Wiring a 100 amp breaker panel requires either #4 copper wiring or #2 aluminum or copper-clad wiring. A 100 amp secondary circuit breaker panel has individual circuit breakers bringing additional circuits to a designated area, like a garage, shop, shed, pool house, or addition.ДЄWG, American Wire Gauge, is the US standard for sizing electrical wiring. Homes today have a 200 amp meter box connecting to the main feeder breaker disconnect and then to a secondary panel (subpanel).

Wiring 100 amp service for a garage or room addition does require an electric permit and professional installation by a qualified electrician following local electric codes. Installation of 100 amp electric service or subpanel needs a #4 AWG copper wire or #2 AWG aluminum or copper-clad wire inside a minimum 1.25 inch, schedule 40 or 80 PVC electric conduit for underground service. Check with your local building department to see if you can get the permit or whether youвЂ™ll require the assistance of an electrician. To complete the skilled work, youвЂ™ll need a permit.
