DC bus positive and negative terminals connection
Then, connect the positive busbar to the battery's positive terminal via a fuse and the negative one to its negative terminal via a shunt. Larger Victron inverter/chargers are equipped with two positive and two negative battery connections, especially for this purpose. Positive and negative busbars are physically identical apart from the red/black colours used by some manufacturers to visually differentiate between. A DC bus is a common term used in electrical engineering to refer to a power distribution system that uses direct current (DC) voltage.

Mongolian Explosion-proof Lighting and Power Distribution Box
Introducing our Explosion-proof Lighting (Power/Repair) Distribution Box, designed for enhanced safety and efficiency in hazardous environments. This series of products have good explosion-proof function, suitable for IIA, IIB, IIC explosive gas environment and various flammable and explosive sites, mainly used in railway, power, metallurgy, petroleum, petrochemical, chemical, iron and steel, aviation, ships and various factory areas. Explosion-proof lights used in hazardous areas where combustible gases and dust exist, which can prevent arcs, sparks, and high temperatures that may occur inside the lamp from igniting combustible gases and dust in the surrounding environment, thus meeting explosion-proof requirements. This robust distribution box complies with IIB/IIC/tD standards, ensuring reliable performance in explosive atmospheres. (hereinafter referred to as KGV Electric), founded in 2011, is a high-tech enterprise focusing on the R&D and manufacturing of explosion-proof electrical appliances and industrial lighting.

What is a secondary lighting distribution box
Secondary distribution boxes, also known as sub-distribution boxes, generally serve specific power supply areas. These boxes have inner and outer doors, powder-coated exteriors, and are designed for safety and aesthetic appeal, with rainproof tops for outdoor work. Let's make an example for clarity: A newly constructed residential area introduces a 10kV power line to a substation. 4kV to the distribution cabinet (primary distribution cabinet), then the outgoing line is led to the distribution box (secondary distribution box) in each building, and finally the outgoing line is led to the distribution cabinet.
