    Battery Cable Gauge

    I am planning on installing a electrical shutoff switch. I presently have some SAE #2 cable available but reading Brattons catalog they advertise a #1 Battery Cable. If I am correct in that the #1 is larger then my #2, is it necessary? This is for a 6 Volt System with Generator.

    The proper spec is a #1 sized cable so i would use that.
    Can you get away with a #2 probably but why!

      We used to buy from NAPA 0 and 00 gauge for 6 volt systems and apply our own copper ends. However, 2/0 , 1/0 , and 1 gauge are larger conductors than 2 for higher amperages and cable length . Using a quality battery cutoff switch which is suggested for an A, one may need to assemble cables to suit switch location.

        Car battery cables can be assembled to your gauge, length desired, and end connections desired from several sources on EBay. When I wire in a floor cut-out, I order my wire from these sources. Incidentally, a very good way to wire a cut-out is in the ground wire to the frame and then a second wire from that same frame bolt to the engine bell housing. Kind of like wearing a belt and suspenders but it does give a good ground. Positive ground of course.

          With oo cables, you could arc weld something, if it broke on the ROAD!!!

            speaking of welding, and this is totally off topic, you can weld if you put 2 12V batteries in series. This might save someone's butt someday......
