Which Gauge Wire?

I'm rewiring a classic with a 6 volt system. Thinking of 14GA for the light draw stuff and 10GA for the heavy draw. I'm ordering the original cloth covered wire now. Suggestions welcome.

The 6v as you probably know is a lot more amps than 12v.

It's been a long time since I was working on an oldie, but I know I've seen heavier-than-10ga in some cars on the main feeds and charging wires.

I have seen a just a few old diagrams for certain cars that actually showed wire sizes. Maybe google some wire diagrams?

Without knowing what loads you have on the particular car you are rewiring, here are some general guidelines as far as wire ampacity.

#14 awg is good for about 15 amps
#12 awg is good for about 20 amps
#10 awg is good for about 30 amps

Making an educated guess I would say you will be OK with 14 and 10. I can't imagine your classic having a high amp electric cooling fan or a high powered stereo system system that would require more consideration.

take whatever gauge wire you would use for the same circuit on 12 volts and double it for 6 volts. some will require thicker than 10 gauge.

there ain't a wire on my '51 Chevy smaller than 12ga, most is 12, but some is 10.
- batt cable is a thick flat steel braid, pos is like 2ga. it's all factory, and all cotton clad

wire

12/10/8 all will be used if done correctly.Wiring is the #1 most neglected and ignored part of a classic.Most are so worried about shiny paint and chrome engine goodies that the damn thing can burn to the ground without warning.
Secondly why 6 volt? are you restoring an all original car for an indoor show circuit competition? if not do yourself a favor and save yourself the heartache.
Buy a 6 to 12 volt conversion guide from Night Prowlers and then it will start easier hot or cold and you will be glad you did,also it will make it easier to add on to in the future if you want any modern conviences such as a radio in the glovebox or an electric fan.

also keep a fire extinguisher in any old car that can easily be reached in the event of the unfortunate blaze.Old insulation burns quickly and ruin a car.

or worse......just my 2 cents .I drive my rods for daily drivers and have never owned a "late model "car so I prefer to be proactive instead of reactitive
and STUPID HURTS!Good luck and have fun.

Thanks for the good advice

I was low on the 14GA for the light draw. Will consider 12GA instead. Also the 8Ga for the heavy lines. Now I'm prepared to talk with the wire sales guy.

Yes its a classic, 38 Mercedes 170 convt. so non-original stuff like 12 volts counts off. Its a small 4 cyl so 6 volt seems adequate. Also its Florida so no cold starts.

I plan to do the 6 volt led bulbs in the tails to add light back there. And yes, Its got a fire extingusher. If you ever do catch fire, a canned beer or coke can save the day. Bang it and pop the top using the carbonation to spray.

Coke would be better because when the police show up and you've just sprayed beer allover your car your going to have a lot of explaining to do.



An ABC extinguisher would be even better
