single phase SDB connection for House wiring

Single Phase SDB Connection for House wiring:

This diagram shows how to make a single-phase SDB connection for house wiring. In this circuit, we use an SP MCB ( Single Phase Minature Circuit Breaker ), a DP MCB ( Double Pole Minature Circuit Breaker ), a Differential switch, and another DP MCB. First, we need to connect an SP MCB, then connect the DP MCB, then connect a Differential switch, then connect all DP MCBs with Differential Switch.

Components used to make the Single phase SDB wiring:

01. SP MCB

Fig 2: SP MCB

MCB SP means single pole it protects only one phase switching. MCB (Miniature Circuit Breaker) Curswitch is the most basic general-purpose switch that you use to control a light or another device from one location. These Switches Have Two Brass-Colored Screw Terminals Connected to the hot Power Source Wires. (MCB) For any Distribution Board, the Protection System Must be Used in The Incomer. Phase and Neutral Single Phase Supply to break. 120-volt circuits, 15-20 amp single pole breaker is typically used.

02. DP MCB

Fig 3: DP MCB

Double pole MCB can control two wires. This circuit breaker is generally used in single-phase electric lines. Double pole MCB circuit breaker input has two wires supply two wires and an output. In a single-phase line, A double-pole MCB circuit breaker is used to give good production. This circuit breaker is provided through phase and neutral circuit breaker, it is very safe. This circuit breaker is preferred for home appliances. A DP MCB usually trips for 2 reasons 1. Overload 2. Short circuit.

03. RCCB

Fig 4: RCCB

The RCCB (Residual Current Circuit Breaker) or RCCB is an electrical protective device. A residual Current Circuit Breaker is specially designed to protect the electrical circuit against earth faults and humans from electrical shock. In this, under normal conditions the load is always connected between the phase terminal to the neutral terminal, hence the flow of the phase current is equal to the neutral current. Earth fault or fault in a power system can cause excess heating, more power consumption, burning or fire, etc. So, protection against earth leakage is very important.
