    I have some 8 conductor 28 ga.. cable, single strand. I want to do
    some simple home automation with it, some small relays, prox switches,
    etc., 10-15 VDC range.

    How much current can I safely have on a single conductor in the cable
    environment?

    Thx.

    How much current can I safely have on a single conductor
    24 ga copper is .0262 ohms per foot, so 100 feet will drop 2.62 volts
    at 1 amp, and dissipate 2.62 watts of heat.

    Figure it out from there.
