Motor Overload Sizing Chart - To determine the correct current transformer rating, multiply the full load amperes by a factor of 1.25. Refer to the specified table and use the controller size and motor amps to select the heater catalog number. Heater table number is found in the column under the type of overload and phase. One manufacturer says for motor and overload in same ambient: Fuses sized in accordance with column 5 must be used in conjunction with properly sized motor overload protection such as overload relays or solid state motor controllers (430.32). Web according to nec,the general requirement for overload sizing be set around 115% or 125% from full load ampere.we should setting the overload relay within this parameter to avoid electric motor from serious damage. Column 5 fuse sizing provides the maximum nec® table 430.52 amp ratings for general purpose applications.
