How do distribution boards work?
A distribution board (also known as panelboard, breaker panel, or electric panel) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits, while providing a protective fuse or circuit breaker for each circuit in a common enclosure.
A distribution board DB is where the electrical supply is distributed from within the building home. The main supply cable comes into the board and is then distributed to the breakers and from there to all the circuits lights fan plugs etc. various sizes of distribution boards are available.
Miniature Circuit Breaker (MCB) automatically switches off electrical circuit during an abnormal condition of the network. means in overload condition as well as faulty condition. nowadays we use an MCB in low voltage electrical network instead of a fuse MCB is much more sensitive to over current than fuse.
Residual Current Breaker (RCB) works on the assumption that the current going to the electronics device must come out from the neutral wire if there is no other way for current flow. In simple words RCB measures the current going inside the connected device and coming out from the device.
