In this guide, we'll break down the 12 main types of distribution boxes in a way that's easy to understand. We'll chat about what each one does, where it shines, and then dive into how to choose the perfect box for your needs. Some of the best distribution types are: 1. Main Distribution Board (MDB) The MDB act as a central section to distribute electricity to various sections with a residential or industrial units. As the name tells the story, the MDB is the hub of electrical power distribution. It receives power directly from the main supply line and then feeds it to various sub-distribution boards or end circuits. Plus, we'll sprinkle in some practical tips to make sure you're not. Residual current protection (RSD/RCCB/RCBO): Detects leakage current and cuts off power to reduce electric shock risk. Surge protective device (SPD): Protects equipment from voltage spikes and surges. Earthing connection: Ensures proper grounding to maintain safety and system stability. It is the first point of power distribution after the utility service entrance or the main transformer.
