Dear experts: The power cables from the distribution room go into the control cabinet built into the freezer. I would like to ask whether it is in compliance with the regulations to run a circuit from above the AC contactor in that control cabinet to another distribution box. If it is not compliant, which regulation does it violate? Thank you!
Does this need to be standardized? You draw power from this cabinet; if there’s a problem with the other cabinet, it may affect the operation of the equipment in this cabinet
It is necessary to consider whether the power cable for the refrigerators can handle the load of two units, as well as the setting of the circuit breakers. Most importantly, it is essential to figure out whether each refrigerator is equipped with a protection switch, just as you mentioned
First, you need to consider running wires from one distribution box to another; determine whether the lower-level distribution box has an impact on the higher-level one. When running wires, it is generally done below the air switch, and efforts should be made to avoid running wires across the AC contactor
This method is not advisable, as it affects the operation of the freezer and poses a risk to one’s own safety.
