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.
DB 701 is a lighter color than DB 703. DB 701 is a light grey color, while DB 703 is a medium grey color.
This statement is not accurate. The decibel (dB) scale is logarithmic, not linear. An increase of 10 dB represents a tenfold increase in sound intensity. So, a sound of 20 dB intensity is actually 10 times louder than one of 10 dB, not twice as loud.
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

Graham Gaunt has written: 'Incomer, The'
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.
DB 701 is a lighter color than DB 703. DB 701 is a light grey color, while DB 703 is a medium grey color.
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.

yes it = 1
dB mean Decibel.
