You can find distribution boxes made from various distribution box materials such as steel, aluminum, PVC, polycarbonate, high-density polyethylene, and thermoset plastics like SMC. Each distribution box material has its own special strengths. For example, you may need flame. While basic electrical boxes are a ubiquitous component on any job site, selecting the wrong material or non-compliant sizes can lead to failed NEC electrical inspections, thermal hazards, and costly project rework. For example, you may need flame retardant features. Since distribution boxes house critical electrical components, they must be designed to withstand various environmental. A distribution box is a low-voltage electrical enclosure that receives incoming power and distributes it safely to multiple outgoing circuits through protective and switching devices such as MCBs, RCDs, RCBOs, fuses, isolators, busbars, neutral bars, earth bars, and surge protective devices.
