The basic structure and technical aspects of electrical distribution boards vary according to places and requirements. A typical electrical distribution box will include a bus bar, fuse links, switches, bypass equipment, and residual current detector (RSD.). At a broad level these components will aid in:
- Residential electrical installation
- The incoming supply circuit breaker or main switch
- Control and distribution board (consumer unit)
- Surge protective devices
- Earth resistance between the electrode and the point of zero potential.
Working with the wires and cables in an electrical system must be safe, and the distribution boards must ensure the following:
- The fuse should block overcurrent through the circuitry.
- There should be enough space for other wires, fixtures, and cables.
- Should not be prone to corrosion.
- Best quality wiring should be used to ensure safety.
