Lighting control mode of street lighting distribution box
The lighting ready board can be divided into two types according to the installation mode in structure: enclosed suspension type (i.e. exposed installation) and embedded type (i.e. concealed installation). The main structure is divided into box shell, panel, mounting bracket, neutral busbar and grounding busbar. There are opening holes for operating main switch and shunt switch on the panel. If you do not need to install all shunt switches, you can use a sealing plate to partially close the opening hole. The knockout holes for incoming and outgoing wires can be placed above and below the box shell. There is also a long round knock off hole on the back, which can be used after the user's own needs. The ready board can also be divided into steel box, stainless steel box, The lighting control modes that can be used in the street lighting distribution box include parallel control, series control, single power supply control, and single lamp control.
