The difference between power distribution box and lighting distribution box (small power distribution unit)

Power distribution box and lighting distribution box (small power distribution unit) are two different types of distribution boxes in the power distribution system. Their main differences are as follows:

Different uses:

Power distribution box: Mainly used to distribute and control the power supply to equipment, machines, power tools and other equipment that require high-power power supply, such as motors, heating elements, etc.

lighting distribution box (small power distribution unit): Mainly used to distribute and control the power supply to lighting equipment, such as lamps, lighting circuits and lighting control systems.

Different load types:

Power distribution box: Designed for heavy-duty, high-power loads, usually requiring larger current capacity.

lighting distribution box (small power distribution unit)es: Designed for light, low-power loads, typically requiring smaller current capabilities.

Circuit protection is different:

Power distribution box: Usually equipped with larger capacity circuit breakers and protection devices to deal with high current and short circuit conditions.

lighting distribution box (small power distribution unit): Smaller capacity circuit breakers and protective devices are typically used because the lighting load is relatively small.

Cable and line specifications:

Power Distribution Box: Thicker cables and wiring are often required to carry high power currents.

lighting distribution box (small power distribution unit): Thinner cables and wiring can be used because the lighting load is relatively low.

Generally speaking, power distribution boxes are used to power high-power equipment, while lighting distribution box (small power distribution unit)es are used to power lighting equipment. They differ significantly in current capacity, load type and circuit protection, so they need to be selected and installed based on specific needs and safety standards.
