This size due to the voltageDrop. All the sizing done by properl calc i.e from MCC to red JB and from JB to motor. All Jbs/acessories according to area clasification. No Govement regulation restriction but I dont find any restriction in code too (may be overlook) if someone experience the same thing can be shared. From northen pakistan.
