AWG size
Posted by Evil Appetite on Thursday, January 25, 2018 2:42 PM

Does anyone here have an idea the AWG size  for distributor wire. I found a whole ot of AWG30 online for cheap and would like to know. The Feb 2005 issue of SA has a feature by Andy Kellock called Bay Views, which has a AWG chart for each type of wire used for electrical, plumbing and other wiring. I no longer have it, as I had to sell everything, and i mean everything last year. So if anyone has the answer, I'd really appreciate it. Even better, If you have the Fed 2005 issue, maybe you could post the charts contents? :)

 

Thanks, Mike

i don't know, but google is your friend...

first search: "spark plug wire diameter" returns:

"Most every other type of street and performance car will use an 8 – 8.5mm diameter plug wires"

You're working in 1:25 scale, so 8.5 x 0.25 = 2.125 mm

next search "AWG size chart" returns:

https://www.rapidtables.com/calc/wire/awg-to-mm.html

select gauge 12 = 2.05 mm or 11 = 2.3 mm

Does that help?

2.125 mm for 1/25 scale seems quite large. More like 1.5 would be about it, math aside.

8.5mm is devided by 25.4, roughly .34 mm, it's pretty easy if you try to remember that 1mm is about 1 inch in 1/25th scale.

AliasTW has it right. For those working in imperial, that works out to be between .013" - .014". Multiply by 25 gets you .325" - .350" in 1:1, which is a decent size for a street plug wire.

The trouble with selecting your plug wires using the AWG sizing is that the guage refers to the copper core, not the diameter of the insulation which is of course the critical dimension for plug wires, and insulation thickness can vary from one wire to the next. The best bet is always to physically measure the material to be used for any wire or plumbing to be sure it is in scale.

For those not interested in measuring for exacting accuracy, selecting by AWG will probably get you 'close enough'. 32 ga. or 34 ga. seems to be the wire that most often comes closest to scale plug wire size. If you are a stickler for scale you may find 30 ga. a tad too large, but the only way to know for sure it to measure it. YMMV

For high performance spark plug wires, you'll want 0.020 wire.  This is measured by the wire and insulation and is the standard for 1/24 or 1/25 scale plug wire.

I often use "eyeball engineering"and if the wiring on a model car looks like garden hoses, then I know that they are too big. Just look at the wiring and hoses under the hood of a 1:1 scale car and one can usually get a fair idea of the sizes they need to replicate. Of course if you need it to be "dead nuts" then get out your micrometers and caliphers.

There are numerous AWG charts on the Web, that give the diameters of the various wire gauges, in both metric and English (what we tend to use in the US).  Easy reference tools those!

For scale plug wires use an AWG 36 gauge wire it measures about .014". out side diamiter, it is used in model rail road aplications. The type you want is the flexable one and comes in different colors.
