18 3 Wire Amp Rating

The amperage rating of a cord is a function of the wire gauge number of current carrying conductors and length of the cord.

18 3 wire amp rating.

The wire size chart below shows allowable ampacities of insulated conductors rated up to and including 2000 volts 60 c through 90 c 140 f through 194 f not more than three current carrying conductors in raceway cable or earth directly buried based on ambient air temperature of 30 c 86 f. 202 shielded power cable 4 x awg 18 eptfe binder over shield not an insulator colors. Likewise when the length of the cord exceeds fifty feet there is a decrease in amperage. 18 awg thermostat wire sold by the foot continuous add the length desired in feet as your quantity and add to cart.

Moisture resistant plastic insulation. When a cord has three current carrying conductors there is a decrease in amperage. 1 the load current rating and the overcurrent protection for conductor types shall not exceed 15 amperes for 14 awg 20 amperes for 12 awg and 30 amperes for 10 awg aluminum and copper clad aluminum after any correction factors for ambient temperature and number of conductors have been applied. For short lengths of wire such as is used in battery packs you should trade off the resistance and load with size weight and flexibility.
