Excuse me, where is the switch in the corridor?

The corridor's own switch is at the entrance of its own stairs, and in the meter box at the height of the side, a meter box is used on this floor, and the door number is usually marked on the switch to prevent other users from switching by mistake. The public switch of this unit in the corridor is generally managed by the property electrician in the public distribution box on the first floor, and individuals are not allowed to operate it privately to avoid accidental danger.

Electrical box primary box, secondary box and tertiary box:

Generally, the main box is the backbone of the circuit and rarely directly enters the equipment. The downward branch is the secondary box, which is connected with heavyweight equipment, and then the tertiary box, which is the part directly connected with household appliances. The primary box is the main switch box, and the secondary box is the power supply flowing from the main switch box, which can be connected with some heavyweight electrical equipment. The third-level box is the electric box we use, which can be connected to the socket light bulb.

The distribution box has the characteristics of small volume, simple installation, special technical performance, fixed position, unique configuration function, no limitation of the site, widespread application, stable and reliable operation, high space utilization rate, less land occupation and environmental protection.

The control center for the reasonable distribution of electric energy among components in the power supply line is the control link for reliably receiving the power supply from the superior and correctly sending out the load electric energy, and it is also the key to obtain the satisfaction of users with the power supply quality. Improving the operation reliability of distribution box is the goal of creating high-quality projects.
