MCB Changeover Connection:
This diagram shows how to connect MCB Changeover Connection. In this circuit diagram, we use a DP MCB ( Double Pole Miniature Circuit Breaker), an MCB changeover, a single-phase energy meter, and a power generator. First, we need to input power in the energy meter from the grid line, then output power from the energy meter to input DP MCB and output power to MCB changeover and generator. If you want to see more clear connection please check our youtube video below the post.

Frequently Asked Questions
MCB Changeover switch finds wide applications in industries as well as in domestic areas especially in Individual Bungalow(IB) for use in low voltage distribution circuits diagram wherever continuity of supply is necessary. It is used for switching to an alternate source of supply from the main supply or vice–versa.
Using an MCB in place of the switch for regular on/off operations is not ideal. While the MCB may be capable of interrupting the electrical flow when switched off, it is not designed for frequent switching operations or may not provide a convenient user experience.
TOMC5-63 3P 63A MCB switch is applied at direct current circuit diagram system, with rated operation voltage DC 220V, rated current flow up to 63A, to protect against overload and short circuit, or also for infrequent changeover for the lines.
MCB could be safely closed on to a fault whereas, it is not allowed in case of the switch with a fuse as it may flashover. MCB has limited fault of the rating - typically 10kA whereas, fuses are available with fault ratings as high as 100kA.
The best-suited type of MCB for domestic appliances, where the current flow load is medium, is type C. Type C MCB trips off when the flow of current flow is 5-10 times more than normal. Type D MCB has a high resistance as they can withstand up to 10-20 times the current flow rate.
