RE: [motm] Suitable Wire Guage Questions

2009-03-12 by John L Rice

Heh, see? (I says to myself!) It took me over 30 minutes to type my
response, mean while someone more qualified to answer like Paul responded. I
could have been doing something more productive . . . . but . . I'm home
sick so . . . I'll cut myself some slack. ;-)

a) well, it depends on your use of the term 'suitable' :)

 

- the smaller the number, the larger the diameter of the wire (seems
backwards, no)

- the gauge is mostly used for carrying *current* (not voltage, that's the
rating of the *insulation*)

- excluding the power supply connector, just about any wire gauge from 22 to
28 is OK. 

 

Bonus question #1: so, why did I choose 22ga wire?

 

- for the power supply side, 18ga is a minimum. When I wire up inside
cabinets, I use 16ga wire.

- you can run RG-174 cable quite long without issues (10ft or more)

 

Bonus question #2: what is the limiting factor on how long you can run coax?

Subject: [motm] Suitable Wire Guage Questions

 

So, we know 22 guage is what's used with MOTM modules for non-audio
connections, but is there a minimum or maximum gauge to go by?
I've got a whole mess of 24 guage wire I've scrapped from dead things at
work, would that still be too thin?
Also have a bunch of 18 gauge which I guess could be a be unwieldy, but
would Too big of wire to a reasonable size add any problems?
Last, I've got a big bunch of rg-174.  How long could I possibly run it to
make normalizing cables inside the modular without problems, 2,3,4 feet or
more?
Thanks,
Tim
