selection of conductors
The selection of conductors is determined from the nominal rated current of all motors working simultaneously on the system.
Order:
1. Determination of ampacity
2. Selection of conductors
3. Control of voltage drop
4. Selection of current collectors
As the premises and statements about output often differ, the following guidelines are to be considered:
Guidelines:
If the individual motor output is known:
Calculation process No: 1a), 1b), 1c) 3a), 3b) 4a)
If only the total installed output per crane is known:
Calculation process No:
1d), 1e) 3a), 3c) 4b)
Determining current: Voltage drop
Selection of current collector:
1. Determination of ampacity
a) Rated currents and starting currents of motors

This table shows typical running values which should only be used if there are no other manufacturers instructions.
Directions: Rated current: IN Cage rotor motors: X = 6 IA = X • IN
Starting current: IA Slipring rotor motor: X = 2
Frequency regulated drives: X = 1.5
If the required motor outputs are not listed in this table, then use formula according to section 1d).
b) Determining of the equivalent continuous currents (ID) at a running period of < 100 % ED (duty cycle).
The rated currents (IN) of the individual motors are multiplied by the reduction factor (fED) for the running period.
ID = IN ^ fED (PD = PN ^ fED)
