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.

No, it is 10 times louder. dB is a logarithmic scale; every 10 dB, the intensity increases by a factor of 10. Thus, 10 dB is 10 times louder than 0 dB, 20 dB is 10 times louder than 10 dB, and 30 dB is 10 times louder than 20 dB.No, it is 10 times louder. dB is a logarithmic scale; every 10 dB, the intensity increases by a factor of 10.

Decibel is abbreviated as "dB."
60 dB: normal conversation 90 dB: lawnmower 120 dB: rock concert 150 dB: fireworks display
80 dB is 10 times louder than 70 dB, and 70 dB is 10 times louder than 60 dB, and so on. Therefore, 80 dB is 1000 times louder than 40 dB.
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
power entering to power panel from the feeder is called incomer powersupply
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 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.
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.

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.

You must find a resistance value for 0 dB as reference. If 1 Ohm = 0 dB then 10 ohms = 20 dB and 100 ohms = 40 dB.
