Complete Electrical House Wiring /Single Phase Full House wiring Diagram
In this video I try to explain the single phase complete house wiring diagram with electrical component. And also this video describe the electrical equipment in distribution board isolation swtich (2 pole MCB) RCCB and Sp MCB electrical fittings (switch, light, socket, and oulets and fan.
In this video. I try to expain the concept of single phase house wiring system with integrated electrical components. And also this video describe how electricity reaches our homes from electric pole, single phase energy meter and main isolation switch and MCCB .MCB.switch.socket and how electricity works in the house.
220 or 240 volt are used in our single phase house wiring SP MCB automatically swotch off during and abnormal condition of the house electrical network menas in overload condition as well as faulty condition
MCB- Minature circuit breaker
MCCB-Molded case circuit breaker
Sp-single pole
Dp-Double pole

Single Phase 120V/230V Distribution and Panel Board Wiring in Home
Single Phase wiring installation is the most common wiring in residential buildings. In Single Phase supply (230V in UK, EU and 120V & 240V in the US & Canada), there are two (one is Line (aka Phase, Hot or Live) and the other one is Neutral) incoming cables from the utility poles to the kWh energy meter and then directly connected to the main distribution board (Consumer unit).
In this step by step tutorial, we will show how to wire a single Phase Consumer Unit Installation at home from Utility Pole to a Single-Phase Energy Meter & Single-Phase Distribution board and then How to connect Single Phase Loads in single Phase Wiring Distribution System in home electric supply system.
Before going in details, you will have to know what is a Single Phase and Three Phase Supply, their applications as well as the role of RCD, MCB, MCCB, CB, DB, MDB, Final and Sub Circuits, Fuses, Switches etc. which is already discussed in our previous electrical wiring installation tutorials.

Single Phase & Three Phase Voltage Levels in the US – NEC
The following different levels of voltages are available for domestics (as residential) and commercial (as industrial) application in the US, Canada (following NEC and CNC) and UK, EU and other countries which follows the IEC e.g. India, Pakistan, UAE, KSA, Philippine, South Africa, Nigeria, Indonesia etc. The following fig at the end of this section will help you easily understand the difference between single phase and three phase voltage levels in the NEC and IEC.
In the USA, for single phase 120V and split phase or 240V, the secondary winging of the distribution transformer mounted on the utility pole is center-tapped i.e. two hot wires (Hot 1 and Hot2) and the center wire as Neutral. This way, the voltage level between Hot and Neutral is 120V single phase and voltage between two hots (Hot 1 & Hot 2) is 240V single phase.
Single Phase Voltage Levels in the USA
Line or Hot to Neutral = 120V,
Hot to Neutral = 208V, (High Leg Delta)
2 Hot = 240V (split phase),
Hot to Neutral = 277V
Hot to Neutral = 480V
Three Phase Voltage Levels in the USA
Three Hots = 208V
Three Hots = 240V
Three Hots = 480V
i.e.
L1 to N = 120V, 208V, 277V or 480V – (1-Φ)
L2 to N = 120V, 208V, 277V or 480V – (1-Φ)
L3 to N = 120V, 208V, 277V or 480V – (1-Φ)
And
L1 to L2 = 208V, 240V or 480V – (3-Φ)
L2 to L3 = 208V, 240V or 480V – (3-Φ)
L3 to L1 = 208V, 240V or 480V – (3-Φ)

In a Three Phase Wiring Distribution System (Star Connection i.e. 3 Phase, 4 Wire System); The power and distribution transformers may be wired in Star (Y) or Delta configuration). For example, the basic configuration for single phase and three phase system in the UK is 230V/400V where the primary of the distribution transformer mounted on the utility pole is connected in Delta Connection while the secondary is connected in Star or Y Connection.
This way, the voltage between any phase and neutral is 230V single phase, while the voltage level between three lines is 400V three phase.
