How many feet per pound of wire?
Feet per pound refers to the number of feet of wire needed to reach one pound in weight. (e.g., AWG 4 wire requires 7.918 feet, while AWG 40 requires 34.364 feet.) Resistance (ohms per 1000 feet). A wire’s electrical resistance depends on its length and thickness. Longer wires provide greater resistance than shorter wires.
How many amps can a wire handle?
American Wire Gauge standards range from 0000 (which can handle up to 302 amps) to 40 (which can handle up to 0.0137 amps). Most household and commercial wiring demands range from 2 (95 amp maximum) or 3 (85 amp maximum) to 14 (15 amp maximum). In the table below, we outline all of the AWG cable sizes and their unique properties.
Why do electrical wires need to be thicker?
For example, electrical circuits with higher amperage ratings require thicker wires to accommodate the load without experiencing excessive heat buildup. Using wires that are too thin for the specified circuit amperage can result in wire failure or ignition.
What is craft wire?
For example, craft wire is thin to support bending, forming, and twisting into jewelry and other craftwork. In the following guide, we provide an overview of what wire gauges are, why they’re important, key considerations, and standard sizes available to help industry professionals select the right wire gauge for their application.
How many ohms does 16 gauge wire have?
Sixteen gauge wire has 4 ohms per 1000 ft. or 0.04 ohm for ten feet. For a 20 foot round trip, 6 amperes at 12 volts will suffer a voltage drop of 4% or one half volt. Because you are tapping off of the line every so often for the various fixtures, the 6 amp draw will be carried only by the first few feet so the voltage drop at the far end won't be the full half volt. You will have to do some math to figure it out exactly, or you can use the worst case of assuming the entire amperes draw goes the full length of the wire, the latter assumption leads to a larger computed wire size. If the transformer is at the middle as opposed to at one end, you get less drop at the far ends all other things being equal.#N#I think bell wire (used for wiring up doorbells) is typically 18 gauge.#N#In any portion of a circuit including the wiring, the number of volts dropped (regardless of supply voltage) is equal to the number amperes being drawn times the resistance in that portion of the circuit.
