An incomer breaker is a circuit breaker that is specifically designated to protect the main incoming electrical supply of a building or facility. It is typically located at the point where electricity enters the premises and acts as the primary protection device for the entire electrical distribution system. If a fault or overload occurs in the incoming supply, the incomer breaker will trip to disconnect power and prevent damage to the system.
A GFCI device in a breaker is intended to trip the breaker open when a ground fault is sensed in the circuit that the breaker is protecting.
When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.
The breaker will have a black wire connected to it. Turn off the main breaker and then disconnect that black wire from the breaker. The breaker will snap into the main bar. Remove the breaker and install the new one. Reconnect the black wire to the breaker and then install the cover and turn the main breaker back on.

The incomer of a Miniature Circuit Breaker (MCB) Distribution Board (DB) should be appropriately rated to handle the total load that will be supplied to the circuits connected to it. It typically includes a main switch or a main circuit breaker that provides overcurrent protection and isolation for the entire board. The rating should be selected based on the total anticipated load, taking into account factors such as diversity and peak demand. Additionally, it should comply with local electrical codes and standards for safety and performance.

A distribution board which has 7 segments , one for Main incomer, three as sub incomer for each phase and three for singlephase outgoing is called a 7 segment DB
A main incomer on a switchboard is the primary connection point for electrical supply, serving as the entry point for incoming power from the utility grid or a generator. It typically includes protective devices such as circuit breakers or fuses to ensure safety and manage the distribution of electricity to various circuits. The main incomer is crucial for controlling and monitoring the overall electrical system in buildings and industrial facilities. Proper sizing and maintenance of the main incomer are essential for reliable operation and to prevent overloads.
The main use of an incomer in transformers is to serve as a primary connection point for incoming electrical power from the supply network. It facilitates the transfer of electricity into the transformer, enabling the conversion of high-voltage electricity to lower voltages suitable for distribution. Additionally, the incomer can include protective devices to safeguard the transformer and connected equipment from faults and overloads.
If a DC supply is connected to the incomer of a transformer, you effectively have a short circuit, because the DC impedance of a transformer (actually, any inductor) is quite low. You will blow something.
If the pump seems to be taking longer to start than normal check the timer in the overload block to see if it has been changed. It may be dropping out too soon while the inrush starting current has not completely collapsed to run current.
The "incomer" of a DB typically refers to the main electrical supply line entering a distribution board or electrical panel. This is where the power from the utility company or generator first enters the building's electrical system before being distributed to various circuits.
