Practical advice

Choice of motor supply cable cross-section

The motor starting current and permissible voltage drop must be taken into

account when choosing the cross-section.

The cable must accept a current at least equal, when used continuously, to the

sum of In + Id/3 where:

In: rated current,

Id: starting current (4 to 8 In), depending on the motors.

Voltage drop

The voltage drop permitted between the source and the motor concerned is 5% for

public distribution networks and 8 % for subscriber or transformer substations.

If the torque of the machine to be driven is low at startup, simply check the voltage

drop for the rated current of the motor.

If the startup torque is high (grain crushers, goods lift, etc.), check the voltage drop

for the starting current.

Protection of the motor supply line

All circuits and motors must be protected against overloads and short-circuits.

Connecting the circuit breaker for use with a single-

phase motor

Two circuit breaker poles must be connected in series.
