I have an application that is calling for AWG20 copper wire. Never heard of this that I can remember. Any help?
 
AWG is conductor size, there are a ton of different other options on stranded/solid and insulation type.
 
I'm pretty sure you're RIGHT, Tim! His application simply calls for 20GA. wire. Has NOTHING to do with any insulation "spec" or whether it is stranded, or not.

From "WIKI":

"American Wire Gauge (AWG) is a U.S. standard set of non-ferrous wire conductor sizes. The "gauge" means the diameter. Non-ferrous includes copper and also aluminum and other materials, but is most frequently applied to copper household electrical wiring and telephone wiring. Typical household wiring is AWG number 12 or 14. Telephone wire is usually 22, 24, or 26. The higher the gauge number, the smaller the diameter and the thinner the wire. Since thicker wire carries more current because it has less electrical resistance over a given length, thicker wire is better for longer distances. For this reason, where extended distance is critical, a company installing a network might prefer telephone wire with the lower-gauge, thicker wire of AWG 24 to AWG 26.

AWG is sometimes known as Brown and Sharpe (B&S) Wire Gauge."
 
You can get 20 AWG with automotive insulation at most auto parts stores. I would probably go to 18 AWG, which is larger, to help with durability. The more strands help with that.
 
That size wire is very small in diameter. I.E. half of what a 10 gauge wire is. Me I would use on any thing on a tractor a 14 gauge or bigger. Go to an auto parts store and read the packs wire come in and you will see the AWG before the size
 
Whats your point either way it is very small diameter wire. And that is what I was trying to point out but hey I have asked you to not comment to my post since we can not seem to get along with each other

oint is that "half" is WRONG. Mis-information! Got it? :lol:

No need to propagate bad "information".
 
Good Mornin Rich, For your information, while lights or other small old tractor electrical loads may require say 14 gauge wire, the typical maximum amps for a coil ignition is around 4 amps. Sure, there's no problem in using bigger wire (which I also often do same as you) but if the electrical load in amps is as low as 4 max amps, 20 AWG may well suffice, subject to insulation and enclosure and temperature etc.

Hope this helps AGAIN no problem in using 14 or 12 gauge or a bigger gauge then electrically required, IM ONLY SAYING the 20 gauge he asked about can most likely handle 4 amps of typical ignition circuitry.

Take care Rich

As noted below, its simply a certain size of wire and AWG stands for American Wire Gauge.

A typical old tractor battery powered coil distributor ignition may carry like 4 amps maximum and 20 AWG wire should handle that SUBJECT TO temperature and if in free air or enclosed etc. etc.

Often on an old tractor I might (like OLD) use bigger wire just for its physical strength such as say 14 AWG instead of 20 and theres no harm if you would use 14 AWG for a 4 amp load.

Weather if be 1/2 or 1/3 the point is it is a lot smaller so why argue about it I was just making a point but that seems to go over your head as it always does

O argument! Just a correction!
