The power distribution box incoming and outgoing line structure is configured as the following manners that: the box body of the power distribution box is divided into an independent incoming line switch room, an independent watt hour meter room and an independent. The utility model discloses a power distribution box incoming and outgoing line structure. The back wall of a power distribution box is provided with hoisting lug type hoisting structures. The power. Eaton's Pow-R-LineT family of distribution switchboards incorporates new design concepts that fit the ever-increasing need for applications on high short-circuit systems, while retaining maximum flexibility, safety and convenience throughout the line. Front-access switchboards align at the rear. 4 KV Substation of the ratings indicated above. The body of the boxes shall have sufficient re- enforcement with suitable size of channels keeping a provision for fixin andle conforming to general. This layout is suitable for a main 11 kV substation, also supplying local low-voltage distribution, and it will be seen that it meets most of the following requirements: Requirement №1 – There is adequate clearance around the equipment and space to withdraw circuit-breakers for maintenance. (1) Wiring method of distribution box 1) Generally, the incoming line of power distribution box adopts five wire system, that is, a, B and C three-way phase line (the general color is yellow, green and red), one way zero line (the color is light blue) and one way ground line (the color is yellow. IEC 61439 is the governing standard for low-voltage switchgear and controlgear assemblies, and it sets verified limits on how a panel can be modified or extended without voiding its compliance basis.
