Can you run 12V through household wire? I have a few hundred feet of it laying around and was wondering if I could use it for the main 12v power line.Seems like it would be easier to run,can fuse it bigger at the source with smaller fuses on the tap ins.Need more light in the TH garage.

Hi,
I'd double up on it--if you have two colors use one for positive and the other for negative. #14 x 4 = about #10 x 2.

Go to "12 volt side of life" and it shows you can carry 10 amps up to 10 feet in 14ga. Happy camping Tom

Why only a short 12v run? I would seem like you could run it for miles considering how big the wires are.Am I missing something trying 12V? You can have a long run in a house with it.

For no more than 15 amps.

Sure you can, good for 15 amps. I would still buy wire to avoid any confusion between 120v & 12v. Or possibly remove it from the sheath.

Hi,
Yes, amperage is what determines wire size. The lower the voltage the more voltage drop becomes an issue.
A wire will get just as overheated from 20 amps @ 12 volts as it will at 20 amps @ 120 volts. The difference is that 20 @ 12 is only 240 watts--whereas 20 @ 120 is 2400 watts.

OK,thanks.Mainly was thinking of the sheath to protect the wires.I can strip the ends back so the sheath can't be seen so as not to confuse the next owner if we ever sell it.

Stranded wire is normally used in boats and RVs in the 12V systems. It flexes better and handles vibrations better. DO IT RIGHT!

So that everyone understands
The INSULATION (wire covering) is selected for the
VOLTAGE (not CURRENT) involved. I have seen a piece
of insulated thermocouple wire connected to 115 v a c
and it SMOKED......the insulation burned immediately.
The COPPER SIZE determines the current limitation.
The insulation is selected for the VOLTAGE (and may
have to be specially chosen for high temperature or
chemical areas). As a general rule, insulation meant
for 120 volt use is rated at 600 volt A C
, and may be safely used for low voltage D C
