Single phase MCB wiring:
This diagram shows Single phase MCB wiring. MCB Connection Diagram. In this circuit, we use two single-phase energy meters, two DP MCBs ( Double Pole Minature Circuit Breaker ), two magnetic contactors, two NO Switches ( Normal Open ), and NC switches ( Normal Close ). Now this circuit is ready for use. This circuit is very simple and easy to make. If you want to know more about this circuit please check our youtube video below the post.

Components used to make the MCB connection diagram:
01. Energy Meter
 |
| Fig 2: Energy Meter |
The measuring device with the help of which the electric power or energy of a circuit is measured is called Energy Meter (Energy Meter). Also called a watt-hour or kilowatt-hour meter. For home appliances, we used a single-phase energy meter. The single-phase energy meter is directly connected between the line and the load. Both coils produce their magnetic fields, when the meter is connected to the supply line, and the load. Energy meters are used in homes and in industrial applications where we want to found that how much energy is being consumed by home appliances and electrical equipment.
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. Contactor

| Fig 4: Contactor |
A magnetic contactor is an electrical device used for load control, automation, and protection. It is much like a magnetic reel. However, relays are generally used for low power and voltage, on the other hand, when we think of high power, these heavy-duty contractors only come to mind. It basically works by switching the load on and off. It has 3 terminals whose inputs are denoted as L1, L2, L3, and outputs as T1, T2, and T3. The circuit of the load is made in automation mode or protection using auxiliary contacts. It has two types of terminals. 1) Normally Open (NO). 2) Normally Closed (NC)
04. NO Switch

| Fig 5: NO Switch |
The operator switch has its contact in Normally Open condition. To make Ladder Logic you need to understand NO contact. A Classic Switch has one Input And one Output. In "No Switch," YoungBoy Raps About Ammunition, Murder, Firearms, and Firearm Attachments Such as a Switch. The contact of the switch whose contact is already open is NO. That is enough to understand. no switch in a circuit, then the circuit will not function as intended. to write a program such that when the red light is on, This switch is now in normally open condition. When you push the switch it will close and the red light will turn on.
05. NC Switch
 |
| Fig 6: NC Switch |
Indicates the contacts of switches or automatic actionable devices. Simply put, the push switches, magnetic contactors, and relays that we use in the factory Normally have Close Contact exists. At this moment the switch will be in normally closed condition. Because already he is sitting close. When turned off the contact will open. To make ladder logic you need to understand NC contact. As already explained. The switch contact is already closed in NC. That is enough to understand.
