Components used to make the Surge protector wiring:

01. DP MCB 

Fig 2: 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.

02. SPD 

Fig 3: SPD

A surge protection device (SPD) or more commonly a surge protector is a device used to protect electronic devices from power surges or transient voltages. A surge protective device is a protective device that limits transient voltages or limits surge current. Surge Protective Devices are Used to Protect Sensitive Electronic Equipment Connected to the Installation such as Computers, Televisions, Washing Machines, and Safety Circuits such as fire Detection Systems and Emergency Lighting. Equipment with Sensitive Electronic Circuitry may be Vulnerable to Damage by Transient Overvoltages.

03. RCCB  

Fig 4: RCCB

The RCCB (Residual Current Circuit Breaker) or RCCB is an electrical protective device.Residual Current Circuit Breaker is specially designed to protect the electrical circuit against earth fault and human from electrical shock.In this, under normal condition the load is always connected in between the phase terminal to neutral terminal, hence the flow of phase current is equal to 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.

04. RCBO  

Fig 5: RCBO

RCBO Stands For Residual Current Circuit Breaker With Over-Current. These devices are designed to ensure the safe operation of electrical circuits breaker, triggering disconnection whenever an imbalance is detected. The other type of electrical fault is the overcurrent flow, which may take the form of an overload or short circuit. The residual current circuit breaker (RCBO) insulation should also operate within the corresponding specifications. This thereby provides protection for people, equipment, and property.

Frequently Asked Questions

How is an SPD wired?

Short direct connections are best. SPDs should be connected Circuit diagram through an appropriately rated circuit diagram breaker, not into the main lugs of the panel. Where circuit diagram breakers are unavailable or impractical, Power supply a fused disconnect switch should be used to connect to the Project system lines and facilitate servicing of the Circuit diagram SPD.

How do you install SPD in a panel?

In order for the SPD to operate, it needs to be connected to a dedicated Circuit diagram double-pole breaker, The power Supply which is equipped with 2 wire terminals, takes up 2 breaker slots and is installed Currenttlou directly next to the main breaker inside the Power supply panel. In most cases, this will be in the 2 breaker slots directly below the Project system main breaker.

What are Type 1 and Type 2 SPD?

Type 1 SPD is characterized by a 10/350 µs current Circuit diagram wave. Type 2 SPD. The Type 2 SPD is the main protection Project system for all low-voltage electrical installations Circuit diagram. Installed in each electrical and switchboard, as it prevents the spread of overvoltages in the power Supply electrical installations and protects the Currenttlou loads.

What is SPD in the main panel?

Surge protection should always be installed at the main service entrance. It is best to use cascaded protection for the sub-panels and equipment, especially in larger facilities where the critical loads are far away from the main. Knowledge is power. Theoretically, any size SPD can be used in a system.

What are SPD types?

There are mainly two kinds of SPDs, parallel-connected and series-connected, the Circuit diagram difference between the 2 series is determined by the Power supply internal circuit diagram itself, most of our lamps use parallel-connected SPD. however, both solutions have SPD degradation and are caused by A sustained over-voltage Project system condition.
