On construction sites, circuit cabinets are very important electrical equipment for power distribution and control circuits. Different types of circuit cabinets play different roles on construction sites to ensure the normal operation of electrical systems and construction safety. This article will introduce the commonly used circuit cabinets on construction sites, including distribution boxes, control cabinets, temporary power boxes, etc., to help readers understand the functions and functions of various circuit cabinets.

1. Distribution box

1.1 main distribution box

• the main distribution box serves as the power distribution center on the construction site, responsible for the supply and distribution of power throughout the site, and is usually installed at the site entrance or distribution room.

1.2 distribution box

• the distribution box is used to distribute power from the main distribution box to each construction area. Multiple distribution boxes can be set up as needed to facilitate flexible control of power distribution.

2. Control cabinet

2.1 lighting control cabinet

• the lighting control cabinet is used to control the lighting equipment in the construction site, including switching lights, dimming and other functions to ensure the lighting needs of the construction site.

2.2 motor control cabinet

• the motor control cabinet is used to control various motor equipment on the construction site, such as cranes, mixers, etc., to ensure the normal operation and safety control of the equipment.

3. Temporary power box

3.1 temporary power box

• temporary power boxes are usually installed near the construction site to provide temporary power supply and facilitate the use of power tools and lighting equipment by construction personnel.

3.2 temporary power box

• temporary power boxes are usually used to connect external power supplies to provide additional power support for construction sites to ensure construction progress and equipment operation.

4. Safety circuit cabinet

4.1 leakage protection box

• the leakage protection box is used to monitor the current situation of the construction site. Once the leakage occurs, the power supply will be cut off immediately to ensure the safety of construction personnel on the site.

4.2 overload protection box

• the overload protection box is used to monitor the load condition of the circuit. Once the circuit is overloaded, the power supply will be automatically cut off to prevent circuit damage and accidents.

5. On-site distribution box

5.1 temporary distribution box

• temporary distribution box it is usually installed near the construction site for temporary power supply and distribution to facilitate the power demand of the construction site.
