The larger the AWG number or wire guage, the smaller the physical size of the wire. The smallest AWG size is 40 and the largest is 0000 (4/0). AWG general rules of thumb – for every 6 gauge decrease, the wire diameter doubles and for every 3 gauge decrease, the cross sectional area doubles.
What is the difference between 4 0 and 4 AWG?
So basically you are left with the amount of current that will be needed, e.g. #4 wire is rated for 125amps and 4/0 is rated for 360amps. If you need to have very high current then the 4/0 would be needed if lower current then #4 would be good.
Is 4 0 the same as 4AWG?
You may guess that 4/0 AWG is just another way to say 4 AWG, you’d be wrong. It goes like this. 4 AWG, 3 AWG, 2 AWG, 1 AWG, 0 AWG, 00 AWG, 000 AWG, 0000 AWG. Where a 4AWG wire is a little less than a 1/4″ thick, a 4/0 is about a half-inch thick.

What size wire do I need for a 200 amp service?
Installation of 200 amp electrical service needs a #2/0 AWG copper wire or #4/0 AWG for aluminum or copper-clad wire inside a minimum of 1.5 inches, schedule 40 or 80 PVC conduit for underground service.
What size wire do I need for a 100 amp service?
When it comes to the lines connecting master and secondary panels, where the line will carry as much as a full 100 amps, use a 2-gauge non-metallic sheathed electrical cable. The cable must contain one or two hot wires depending on your needs, one neutral wire, and one ground wire. Each wire should be 2-gauge in size.
What is 4 AWG wire used for?
This wire is 4 AWG, good for 95 Amp when used in conduit with less than 3 conductors. This wire is rated for use in dry or wet locations, raceways, or conduit. It can be used outside exposed to the weather as well, though the insulation is not 100% UV-proof and installation in conduit is recommended.
What does 4 AWG wire mean?
Wire gauges range from low numbers to high numbers, with smaller numbers referring to smaller diameters and larger numbers representing larger diameters. For example, AWG 4 is 0.2043 inches in diameter, and AWG 40 is . 0031 inches in diameter.
Is AWG bigger than 4 AWG?
American wire gauge (AWG) is a standardized wire gauge system for the diameters of round, solid, nonferrous, electrically conducting wire. The larger the AWG number or wire guage, the smaller the physical size of the wire. The smallest AWG size is 40 and the largest is 0000 (4/0).
What is the diameter of 4 AWG wire?
AWG Metric Conversion Chart (AWG to mm) American Wire Gauge (AWG) Diameter (in) Cross sectional area (mm 2 ) 1 0.289 42.4 2 0.258 33.6 3 0.229 26.7 4 0.204 21.1.
What is 4 AWG amp rating?
How many amps can a 4 gauge wire handle? It has a rated ampacity of 85 amps at 75°C. This means that, for average use, the 4 gauge wire can handle up to 85 amps safely.
How many amps can 4 0 copper wire carry?
4/0 Welding Cable carries 310 Amps for 600 volt in-line applications. 4/0 Welding Cable is an extremely flexible cable with pure fine stranded copper.
Is higher AWG better?
In general, a lower AWG number is better than higher AWG. AWG is of primary importance for wires that will carry electrical power — for example, home or business electrical wiring, extension cords or high-power wire in automotive or audio use.
How do you determine AWG wire size?
Stranded wire gauges should be measured by calculating the equivalent cross sectional copper area. First, measure the bare diameter of a single strand and locate the circular mils value in the row that matches your measurement. Second, multiply the circular mils by the number of strands in the cable.
How many amps is #4 aluminum good for?

What size wire do I need to run 100 amp Service 150 feet?
What is the right wire size for 100 Amp service 150 feet distance? You should get 2/0 AWG Copper wire or 4/0 AWG Aluminum wire for single-phase circuits. And, 1/0 AWG Copper wire or 3/0 AWG Aluminum wire if you have three-phase circuits. For these wires, the average voltage drop should be 3%.
What size wire do I need for 225 amp?

Can you run 220 on 100 amps?
Yes, you can. As long as it 240v with a neutral and ground. The only downside is other loads. If the new load with the other loads goes over 100a, you will trip the breaker.
Can I run a 100 amp sub panel off 200 amp main?
Of course you can, you can add the 100 amp breaker to your 200 amp as long as it isn’t overloaded, to start adding the subpanel you must first calculate how many yards it will be from the main panel to the subpanel, there is a formula that calculates how much friction will be on the wire at the connecting distance, Mar 14, 2018.
