The size of the copper wire that delivers power inside an extension cord is called its American Wire Gauge (AWG), or gauge for short. The most common extension cords come in 16, 14, 12 and 10 gauges.
In this regard, what are the ends of an extension cord called?
An extension cord, power extender, drop cord, or extension lead is a length of flexible electrical power cable (flex) with a plug on one end and one or more sockets on the other end (usually of the same type as the plug).
Secondly, what are the different types of wire? Color Codes – Different color wires serve different purposes, like:.
- Black : Hot wire, for switches or outlets.
- Red : Hot wire, for switch legs.
- Blue and Yellow : Hot wires, pulled in conduit.
- White : Always neutral.
- Green and Bare Copper : Only for grounding.
Likewise, what is a grounded extension cord?
Medium-duty cords usually are grounded extension cords, which include the third wire and plug prong for grounding. They have plugs that accept three-prong grounded appliance cords. Uses: televisions, computers, and other devices that draw up to 10 amps of power.
How thick is a 12 gauge extension cord?
14-Gauge Cords: Any 14-gauge cord between 0 and 50 feet long will adequately handle loads between 10 and 15 amps. 12-Gauge Cords: If your tool load is between 10 and 15 amps and the length of the cord is 50 to 100 feet, you need a 12-gauge cord to safely power any tool.
