In accordance with US electrical codes the max current for circuits utilizing 12 It depends on whether you mean bare wire hanging in the air, plastic insulated wire in a cable, or in a conduit, or in a transformer. In house wiri This accounts for the round trip distance of the run. Found inside Page 127The amperage rating of a fuse or breaker is matched to that of the circuit it protects. If a circuit draws more current than it Most 120-volt circuits contain 14- or 12- gauge solid copper wire. Most 240- volt circuits use 12- or Answer: A number #12 Awg is rated a 20Amps for copper 60 ( CU) or 15 amps for Aluminum 60 column. American Wire Gauge (AWG), also known as the Brown & Sharpe wire gauge, is a logarithmic stepped standardized wire gauge system used since 1857, predominantly in North America, for the diameters of round, solid, nonferrous, electrically conducting wire. Multiply the conductor's ampacity by the derating percentage. Found inside Page 72Electricians have been upgrading electrical systems in this manner for years, and you can do it too. A 15-amp circuit will generally contain 14-gauge wires, while a 20- amp circuit will require 12-gauge wires. I am a little bit amazed, not by the question but the fact it was asked on Quora. The answer is straight. There is no personal opinion. If you are watts), and a house voltage of 120 volts: 2400 watts 120 volts = 20 amps. Found inside Page 424The amount of electrical current a conductor can carry is measured in ampacity , a shorter term for ampere - capacity .

Although wire is available in many different sizes and colors, the purpose is still the same: To transfer an electrical current from one device to another. AWG - American Wire Gauge Converter - American Wire Gauge (AWG) vs. cross sectional area converter. Depending on how much wattage is being transferred through the cable and the distance the cable is being run, different gauge of Amps = Watts divided by volts; Feet = One-way wire distance % Volt Drop = Percentage of voltage drop acceptable for this circuit (typically 2% to 5%) 2. NM (non-metallic sheathing) wire is no different. Add To Cart. No. SAE Wire Areas (Min cma**) Nominal Metric Equivalent size, mm. Wire Gauge Chart vs Amps vs Length. AWG is sometimes also known as Brown and Sharpe (B&S) Wire Gauge. For example, a 12 gauge wire is commonly rated at 20A for 110V AC home usage, but in automotive 12V DC use 12 gauge wire is commonly used for circuits carrying 60A! The larger the AWG number or wire guage, the smaller the physical size of the wire. Wire size ratings are based on *amperage alone, not wattage. 30 15 20 Instead, you need to match the original wiring size. Wires are sized according the wire "gauge", abbreviated AWG. This tool needs no maintenance Fully revised and updated, this convenient guide covers the latest industrial equipment as well as all the tools and machines prevalent in older plants, even those from the early 1970s and before. Check your local electrical code for the correct current capacity (ampacity) for 12 gauge Romex is rated for 20 Amps and is commonly yellow jacketed. The gauge of the wire dictates the amount of current that can safely pass through the electrical wire. For example, a 10-gauge wire is bigger than a 12-gauge wire. Refer to the chart below: Electrical current is measured in amperage (amps), and each wire gauge has a maximum safe carrying capacity.
