Instead of these complex stuff, wire gauge tables and charts are the alternative helpful resources based on the AWG. In addition, there are some special gauges such as 0000 (4/0), 000 (3/0), 00 (2/0) used for wire diameter and thickness larger than 0AWG. In the list of standard sizes as integers, 4/0 (0000) is the largest diameter and 40AWG is the smallest diameter printed on AWG. In AWG, there are a total of 44 gauges assigned to different numbers. The integers (as numbers) printed on the American Wire Gauge shows the gauge size.
Electrical Wire & Cable Size Calculator (Copper & Aluminum). We will show a solved example as well as the related AWG Wire size table for this in the following sections. That’s where we need an AWG tool and related charts and tables to it.īased on the wire size chart, you may select an “8 AWG” wire size and 50A of circuit breaker for 240V, 9000W, 240V water heater element wattage. If so, the small wire for higher load may get hotter which leads to burn the wire as well as damage the circuit breaker and connected appliance to it. #WIRE AMPACITY CHART INSTALL#
For example, if you need to install a water heater, what size of wire will you select? As you can’t use the same size of wire for all the electrical load points and higher wattage appliances. In any electrical installation system whether domestic or industrial, the selection of proper wire size and appropriate size of circuit breaker is very important.
Why are Wire Gauge Charts & Tables Important? If it is fixed properly in the slot (not hole), this is the exact gauge size (printed on that specific slot) of the wire. To use the wire gauge tool to find the suitable gauge size for a particular wire, simply remove the outer insulation and insert the wire conductor in the wire gauge slot one by one.
It is a small circular shaped disc where different but common numbers are printed on it in accordance with the specific slots and holes. If you are on the job site and need to know the wire size gauge for the particular load, one of the quick solutions is to use the handy device known as wire gauge tool.
AWG/SWG to mm/mm 2, inch/inch 2 & kcmil Calculator & Conversion. Standard Wire Gauge “SWG” Calculator – SWG Size Chart & Table. American Wire Gauge “AWG” Calculator – AWG Size Chart & Table. Good to know: The American Wire Gauge (AWG) is also known as B and S Gauge (Brown & Sharpe Gauge). the higher the AWG size, the lower the ampacity and vise versa. In short, the ampacity is inversely proportional to the size of AWG integers (from 0000AWG to 40AWG) e.g. For example, the 14AWG size is a suitable wire for a 15Amp circuit breaker, whereas the 8AWG size is most appropriate for 40Amps of circuit breakers and load points. One thing should be noted about the AWG that the larger the integer, the smaller the thickness and diameter of wire. One of the most important roles of American Wire Gauge is to measure the current carrying capacity in Amps of wire (aka Wire Ampacity = The amount of maximum current that a conductor can carry continuously without exceeding its temperature rating. The AWG is used to exactly measure the diameter of a particular conductor (such as solid, stranded, round and non-ferrous (alloys or metals that do not contain any appreciable amounts of iron) materials e.g.
