7 Selecting per NEC & EC Selecting per NEC Article 43 of the US National Electric Code includes two methods for properly sizing disconnect : 1. Single motor application A properly sized disconnect switch for a single motor will: a) have an ampere rating greater than or equal to 115 percent of the rated motor full load current; or, b) have a HP rating greater than or equal to the rated motor HP (at applied voltage) if the disconnect switch under consideration is HP rated. 2. Combination load application A properly sized disconnect switch for a combination load will be selected by adding all the simultaneous individual loads in the circuit under consideration. Using motor nameplate information, load information, and tables from section 43 of the NEC, determine one equivalent full load current and one equivalent locked rotor current. The equivalent locked rotor current can be used with table to determine an equivalent HP rating. Select a disconnect switch: a) greater than or equal to 115 percent of the equivalent full load current; and, b) greater than or equal to the equivalent HP rating.

9 Definitions AC Alternating current Current that reverses its direction of fl ow twice per cycle. Ambient temperature Temperature of the air surrounding the unit. Amp rating The basic unit of measurement for electric current (columbs / seconds). Conventional thermal current th Value of the current the disconnect switch can withstand with poles in closed position, in free air for an eight hour duty, without the temperature rise of its various parts exceeding the limits specifi ed by the standards. Cycle duration Total time of the on-load + off-load period. DC Direct current Current that fl ows in only one direction. Electrical endurance Number of on-load operating cycles. EC environmental protection type see page.5. Full load amp current FLA The current required by a motor to produce full-load torque at the motor's rated speed. nductive load An electrical load characterized by having signifi cant inrush (5 to 6 times FLA for typical design-b AC induction motors). kw Kilowatts (1 watts) Lockout/Tagout Means of removing power from electrical equipment during inspection, service or repair. Make / Break / Mechanical endurance Number of off-load operating cycles. Poles Means of connection poles using wires or bus bars to increase breaking capacity of load. Power factor The relationship between working power and total power consumed. Power factor measures how effectively electrical power is being used. Rated insulation U i Voltage value which designates the unit and to which dielectric tests, clearance and creepage distances are referred. Rated operating current e Current value stated by the manufacturer and taking into account the rated operating voltage U e, the rated frequency, the rated duty, the utilization category, the electrical contact life and the type of protective enclosure. Rated operating voltage U e Voltage value to which utilization characteristics of the disconnect switch are referred, i.e. phase-to-phase voltage in 3 phase circuits. Rated short circuit making capacity cm The rated shortcircuit making capacity of a disconnect switch, a disconnector or a switch-disconnector is the value assigned to equipment at the rated operational voltage, frequency (if any) and specifi ed power-factor for AC or time constant for DC. t is expressed as the maximum prospective peak current under prescribed conditions. Rated short time withstand current cw The rated shorttime withstand current of a disconnect switch, a disconnector or a switch-disconnector is the value that the equipment can carry without damage, under the test conditions specifi ed in the relevant product standard. The value of the rated shorttime withstand current shall be not less than twelve times the maximum rated operational current unless otherwise stated by manufacturer and the duration of the current shall be 1 s. Resistive load An electrical load characterized by not having any signifi cant inrush current. Short circuit protection coordination Co-ordination types "1" and "2" are defi ned in EC Type 1 coordination There has to be no discharge of parts beyond the enclosure. Damage to the contactor and the overload is acceptable. Type 2 coordination No damage to the overload relay or other parts has occurred, except that welding of contactor or starter contacts is permitted, if they are easily separated. Time constant Ratio of inductance to the resistance: L/R = mh/ohm = ms. Torque The force that produces rotation. t is commonly measured in pound-feet (lb-ft). Torque applies to such things as motor operations, handle rotations, wire tightening. NEMA environmental protection type see page.49. Volt The unit of electrical potential difference and electromotive force..48 Low Voltage Products & Systems AC 1-11/3 ABB nc
