Reliable; the luminaire input cable must not be twisted or twisted; the luminaire cable must be selected to meet the capacity requirements of the luminaire's power; the luminaire cable must be marked with a permanent mark and a phase mark at both ends. 4.5 Box and box installation box should be aligned perpendicular to the wall when installing. The vertical deviation is not less than 2MM. The inlet and outlet boxes are neatly arranged with appropriate margin. Wires with different circuits, different voltages, and AC and DC wires shall not be threaded into the same pipe. The wires shall not have joints and twists in the pipe. The wires shall penetrate into the pipe. At the exit, a sheath shall be installed to protect the wires. Before laying the cable, carefully check the cable for mechanical loss and conduct insulation shake test. The installation of the morning power and lighting distribution box, the quality standard response to the national electrical engineering construction specifications. The floor power distribution box should be firmly installed on the angle steel or channel steel base, fixed by screws, and grounded. The pipe entering and exiting the line should be about 10 cm above the base surface in the foundation. The installation position size is required according to the drawings, and the door can be installed against the wall without opening the inspection door. The floor-standing power distribution box is installed with a vertical straightness of 1.5 mm per meter and a disc indirect seam of 2 mm. The lighting box is generally installed on the wall.
