Circuit switch inside the distribution box
A distribution box typically contains a main double-pole MCB, individual single-pole MCBs for circuits, RCCBs for protection, and sometimes isolation switches.Main SwitchThe main switch in a distribution box is usually a double-pole MCB (Miniature Circuit Breaker), which controls the overall power supply to the board. It has the highest capacity among the switches in the box and is responsible for distributing power to all other circuit breakers when turned on. In domestic installations, a 63A double-pole MCB is commonly used as the main switch, connecting the incoming phase and neutral lines .Individual Circuit BreakersFor individual circuits, single-pole MCBs are used to protect and control specific loads such as lighting, fans, or appliances. In some cases, double-pole MCBs may also be used for special loads that require both phase and neutral protection . These breakers automatically trip in case of overload or short circuits, preventing damage to wiring and connected devices.Residual Current Circuit Breakers (RCCBs)RCCBs are protective devices installed in the distribution box to prevent electric shocks and leakage currents. They detect imbalance between live and neutral currents and disconnect the circuit if a fault occurs, enhancing safety in domestic and commercial installations .Isolation SwitchesSome distribution boxes also include isolation switches, which are not meant to switch power under load but provide a visible and safe disconnection point for maintenance. These switches allow technicians to safely work on circuits without risk of accidental energization .SummaryIn summary, a typical distribution box contains:Main double-pole MCB: Controls overall power supply.Single-pole MCBs: Protect individual circuits.RCCBs: Provide protection against leakage currents and electric shocks.Isolation switches (optional): Ensure safe maintenance and visible disconnection . These components work together to ensure safe, organized, and efficient distribution of electricity throughout a building.
