plastic wire gauge - mm

[gazdkw82]

I seen somewhere not so long ago a plastic credit card size wire gauge. It had all different sized cut outs in it so you could offer up a conductor in order to correctly size it. cant find anything decent that's measured in mm.

Its just to quickly size a conductor if in doubt

Holy cow this one is expensive for what it is!!!

Like you say, finding one that isn't in AWG or SWG sizes is tricky.

make your own from a bit of metalplate' . calculate the diameter using A = Π Γ²

 

[gazdkw82]

that's the style rsgaz, however.... £27! are they serious.

That one I linked to, I'm pretty sure that is giving the diameters, rather than the CSA.

You'd need to work it out differently for stranded if you make your own.

Do you have some digital calipers?

 

[gazdkw82]

yeh I have some.

if such a thing doesn't exist then I think we should design and make one as a forum ;-)

hmm, a forum tried to design a dog and the result was diane abbott..

I just keep red, blue, yellow and 10mm crimps in my bag. That does me for 99% of my cable sizing issues.

You really don't like Her Tel do you?

 

[rsgaz]

yeh I have some.

Then just make a table to print out of CSA & diameter and use the calipers to check.

I can upload the xlsx file if you want it to make it look prettier or change it about a bit.

It is "high grade tool steel". If you want the best...

That said, some of the sizes are a bit odd: 2.0, 2.24, 2.5 ... 3.0, 3.15, 3.55. Anyone know why. Just curious.

Anyone know why. Just curious.

That gauge turns out to be the diameters, so it's probably more useful as a drill bit gauge than a wire gauge TBH.

Just by hunting around a bit, wire for fencing seems to be popular in those sizes, but I can't seem to find a standardised 'gauge' list that has those figures.

You can see lots of the odd figures from that Kennedy gauge used there.

Ahh, found it, it's BS4391:1969 metric wire gauge, not a converted imperial one as I has expected it to be, because of the odd values. But loosely based on the very old 'Birmingham Wire Gauge'.

Micrometer!

Iv Defo seen somewhere a credit card sized piece of plastic with cut outs to offer conductors up to

Most of the cable has its size printed along its length now

 

[gazdkw82]

New cable does but I see old cable all the time with no size info

how are you going to tell with a sheathed cable only by sight and that's the most common way

 

[gazdkw82]

By taking it out from the accessory/termination point and using the end bare copper available
