Wire sizing

My new engine has AC voltage supply with 18 gauge wiring, would the wire size be sufficient to supply a 20 watt hand warmer?

Snow Removal Apparatus I own:
Ariens ST1530DLE, and good ole arm powered scrapper.
The 15 HP is a new Ducar engine sold
by Princess Auto in Canada.

Depends on the voltage. If the snow blower is putting out 12 volts, 20 watts is only about 1.7 amps. 5 amps and above and you would want 16 gauge. Is there anything else drawing from that wiring like a light? Also, do you know how much output your machine has electrically?

Hello Norm, glad to see your back and hopefully doing well. From a bit of browsing, it looks like an 18 ga wire will handle 6 amps of load. 20 watt hand warmers divided by 12 volts = 1.6 amp draw, so the 18 ga is large enough to handle the load.
The formula is Amps = Watts divided by volts.

Uh Oh, my slow finger was to late typing, JTD beat me to the draw.

Experience is something you don't get until just after you need it.

Thanks for responding JTD and the AC side of the supply is only used for the hand warmers. The charging coil is supposed to output 5 to 7 amps.

Grunt thanks for the exact information I needed.
