not certain what knowledge you have.
you should have regulations for wiring equipment like this. - maybe not.
Understanding the load of a control circuit is very important
In a non PLC environment it is common practice, here, to calculate maximum demand. similar to the total number of devices that can be loaded at the same time.
This is slightly different, but, consider the types of motors/solenoids and their magnetising/starting currents.
you will need to take this into your calculations or you may suffer false tripping of circuit breakers. HRC fuses, not commonly used any more,need to carefully sized as well.
