16 3 Wire Meaning

He diameter of the cable does not include the outer jacket of the wire but only the copper wire on the inside.

16 3 wire meaning.

The wires are 12 gauge. Extension cord lengths determine the cord s power capacity. Generally speaking the smaller the gauge number the thicker the cable. The n gauge wire diameter d n in millimeters mm is equal to 0 127mm times 92 raised to the power of 36 minus gauge number n divided by 39.

The important part to consider in determining a cables current carrying capacity is the cross sectional area of the cable. A wire that is true to gauge will meet and or exceed the diameter of the copper for its awg rating. This decreases the power the cord can deliver to connected devices. However if you simply want to know what gauge extension cord you need to support a particular amount of.

When they say cord they describe a flexible cable not used in fixed wiring nor in a conduit but used to connect an appliance to a plug. This is the current standard for residential installations. D n in 0 005 in 92 36 n 39. The n gauge wire diameter d n in inches in is equal to 0 005in times 92 raised to the power of 36 minus gauge number n divided by 39.

They also use the term extension. The standardized method of measuring the thickness of a cable american wire gauge or awg was established in 1857 in the united states. Below is a chart of different wire gauges. Should not exeed more than 15 amps or so.

16 gauge light duty. This is standard for residential nm cable. This form of measuring cable thickness is used specifically for electrically. For example a 14 3 cord contains 14 gauge wire and has three conductions inside.

That s right we re giving you the chart right up front without making you read through paragraphs of text. The gauge also determines the resistance of the wire and its weight per unit of length. Yes those are american terms which are also used in canada where i live. Extension cord size chart wire gauge vs length.

When dealing with wire gauge the characteristics of a wire usually specified on a chart is the wire s size specified in awg diameter area feet per pound ohms per 1000ft and current capacity in amps. Cable contains three insulated wires plus a ground wire. If you cut it open within the cable you should have 3 conductors plus a ground wire. The 16 is the guage or thickness of each conductor and 3 is the number of conductors in that cable.
