    Full Load Current inAmperesCurrent Values Based on UsualSpeed and Normal Torque

    For full load currents of 206V and 200VMotors, increase corresponding 220V valueabove by 6% and 10% respectively.

    Current CarryingCapacity in Amperesof Flexible CordsBased on Ambient Temperatureof 30C (86F)

    Amperage shown is for not more than 3conductors in a cord. If cord has from 4 to6 conductors, decrease to 80% of valuesshown.

    The ampacities under subheading A areapplicable to three conductor cords andfour conductor cords with three conductorscarrying current. The ampacities under sub-heading B are applicable to two conductorcords and three conductor cords with twoconductors carrying current.

    NOTE: On extension cords over 50 feet,derated by two wire sizes.

    Amperage Ratings forMetric Copper*General use ratings only. Check withappropriate approval agency for specificapplications, as ratings vary from country to country.

  • Abbreviation for American Wire Gauge.

    Designation for appliance wiring material.

    Electric current that continually reverses itsdirection. It is expressed in cycles per second(hertz of Hz).

    The temperature of a medium (gas or liquid)surrounding an object.

    A standard system for designating wire diameter.Also referred to as the Brown and Sharpe(B&S) wire gauge.

    (See Current Carrying Capacity)

    The unit of current. One ampere is the currentflowing through one ohm of resistance at onevolt potential.

    Relief of mechanical stress through heat andgradual cooling. Annealing copper renders itless brittle.

    The range of frequencies audible to the humanear. Usually 20-20,000 Hz.

    A commonly used industry term for partialsurge protection, usually a single MOV pro-tecting line-to-neutral (see Full protection).

    A fibrous or metallic group of filaments inter-woven in cylindrical form to form a coveringover one or more wires.

    The voltage at which the insulation betweenconductors breaks down.

    A group of wires of the same diameter twistedtogether without a predetermined pattern.

    The twisting together of two or more insulatedconductors to form a cable.

    The ability of a dielectric material betweenconductors to store electricity when a differenceof potential exists between the conductors. Theunit of measurement is the farad, which is thecapacitance value that will store a charge ofone coulomb when a one-volt potential difference exists between the conductors. InAC, one farad is the capacitance value thatwill permit one ampere of current when thevoltage across the capacitor changes at a rateof one volt per second.

    The complete path of an electrical current.When the continuity is broken, it is called anopen circuit; when continuity is maintained, itis called a closed circuit.

    To hold the current or voltage at a specificfixed level.

    The level of voltage required to activate aclamping circuit, also called let-through voltage.

    Permanent deformation of the insulation due tomechanical force or pressure (not due to heatsoftening).

    A system for circuit identification through useof solid colors and contrasting tracers.

    An insulating or jacketing material made bymixing two or more ingredients.

    In a wire or cable, the measurement of thelocation of the center of the conductor withrespect to the geometric center of the surroundinginsulation.

    An insulated wire suitable for carrying electricalcurrent.

    The parts of the connector that actually carrythe electrical current, and are touched togetheror separated to control the flow.

    A test to determine whether electrical currentflows continuously throughout the length of asingle wire or individual wires in a cable.

    A flexible insulated wire.

    Ionization of air surrounding a conductorcaused by the influence of high voltage.Causes deteriorization of insulation materials.

    The minute cracks on the surface of plasticmaterials.

    Abbreviation for Canadian Standards Association,a non-profit, independent organization thatoperates a listing service for electrical andelectronic materials and equipment. TheCanadian counterpart of the UnderwritersLaboratories.

    The maximum current an insulated conductorcan safely carry without exceeding its insulationand jacket temperature limitations.

    A unit of measurement for noise filtering capability. The amount of noise a filter caneliminate is measured in decibels.

    The voltage that an insulation can withstandbefore breakdown occurs. Usually expressedas a voltage gradient (such as volts per mil).

    The capacitance measured directly from conductor to conductor through a single insulating layer.
