Understanding RCCB, RCBO And Difference Between Them

About RCCB

RCCB (residual current circuit breaker) detects current difference between neutral and live conductors. The difference is also known as ‘residual current’. Proper functioning circuits will have balanced neutral and live current and the residual current occurs when there is some potential shock hazard or fault. The device is an RCD i.e. residual current device class of item and circuit breaker, which is a part of its name, indicates that the electrical product sits within costumer unit with the other CBs (circuit breakers).

It should not be confused with MCB current rating at which it will trip out.  

Defining RCBO

RCBO means residual current circuit breaker with over current protection, which is a combination of RCCB and MCB.

When current leakage occurs, the RCCB (residual current detecting element) will trip the entire circuit. Similarly, in case the circuit is overloaded then components of internal magnetic/thermal circuit breakers are capable to trip the electronic device.

Dissimilarity Between RCCB And RCBO

Both the electrical devices are normally found in fuse box, which is known as breaker panel or consumer unit. RCCB will only identify current leakage from circuit. On the other hand, RCBO can notice over current and current leakage from the circuit. The device recognizes over current in the same manner as MCB does. RCBO is usually utilized as replacement for MCB in consumer unit.

RCCB is older as well as simpler technology than RCBO and is widely trusted. But RCBO is newer product and uses a built in microcontroller and now becoming popular.

Difference Between MCB And MCCB

Circuit breakers are installed in power infrastructure for safety reasons. They are introduced to make sure that fire hazards or any sort of electrical issue would not occur in home or office when system experiences ‘short circuit’ or ‘overload’. This is the only reason; MCB or MCCB should be installed.

Most of the people are confused about the dissimilarity between MCB and MCCB. Both of these devices are circuit breakers yet there is a major difference between them and they are used for specific purposes.

Before we start discussing about the key features, it is more important to know their actual meaning.

The Meaning

MCB, an abbreviated form of “Miniature Circuit Breakers”, is an electromechanical device that protects electrical circuit from over-current. On the other hand, MCCB is a short form of “Molded Case Circuit Breaker” that is a kind of electrical protection device used for varied voltages.

Main Difference

Judging from power capacity, MCB is utilized for low energy requirements such as small electrical circuits and home wiring. Whereas, MCCB is more suited for delivering energy for high power devices and used in commercial and industrial installations.

MCBs are rated under 100 amps with interrupting rating of under 18000 amps. While, MCCB comes with adjustable trip making it is suitable for higher models. Normally, this kind of circuit breaker would offer Ampere ratings as high as 2500 or as low as 63 completely depends on what is necessary. Interrupting rating can be nearly 10,000 amps to 200000 amps.

Although MCCB has higher capacity than MCB, both the devices are classified under the low voltage circuit breakers and therefore, they should respond to the standards that are set by the IEC 947.  For the sake of convenience, some MCCBs possess electrical motor operators that means they can be tripped only with the help of remote control. For commercial use, they can be utilized as standby power running on automatic transfer switch.

So whether it is restaurant, hotel, hospital, office, mall or your home, you require professional wiring to enjoy benefits of modern electrical infrastructure. This is the reason, when buying cables and wires, quality, brand and appropriate current rating/size should be kept in mind. Otherwise you may have to upgrade these at a later stage or even risk short-circuit in case of current overload.

There are lots of brands present in the market and the credible ones include KEI, Finolex, Havells and Polycab, amongst others. It will be a better idea to purchase the best ones, so that there is minimal quality risk. To buy the above professional quality cables and wires, traditionally you would visit a local electrical shop or even ask your electrician to source it for you. But now with advent of the Internet, you can buy wires online at the convenience of your home.

Why to Buy Branded Wires?

Using branded wires offers increased reliability and therefore, they are better to use than local or low quality wires. They are robust and capable to withstand full electrical load. Branded wires and cables usually have good quality PVC sheath, which does not easily split or suffer any other sort of damage. And the electrolytic copper used is 99.99% pure and of full gauge as per size of the wire specified. Local cable manufacturers, in order to cut costs, may compromise on quality of the copper, quality of the sheathing and also on the actual supplied length, since most of these wires are sold in readymade packs of 90 metres or 180 metres or similar.

LED Lights – Major Source Of Illumination At Present And Future

Nowadays, LED lights are in high demand in residential homes, retail spaces, commercial buildings, new construction, etc. This fast shift to the new source of light in the last few years has excited the entire industry. The demand will keep increasing as new technology converts the source more valuable. You can buy LED light online and offline too. Lots of physical and virtual stores are present as a help and you can choose the one that seems to be the most convenient medium.

Safe to Use

LEDs are completely safe to use when sourced from well-recognized brands. They do not contain harmful chemicals or gases and can be disposed in open. Also, LEDs are safe to handle since they are cool when being touched and run on very low-voltage thus minimizing injury risk from electrical lines.

High Efficiency

Long lifespan, low energy consumption, small size, improved physical condition, etc. are some of the major qualities of LED lights. LEDs have less environment related issues and now they are cost efficient too and hence replacing conventional lighting sources like GLS Lamps, Flourescent tubes/CFLs,, Halogens, etc. LEDs use fewer watts than halogens and CFLs without making any compromise with light output.

Durable Source

Sturdy components are used to make LEDs instead of filament or neon gas. They are highly rugged and can easily withstand the rough conditions. LEDs are resistant to vibrations, shock and external impacts like high or low temperature, so they can be used as outdoor lighting source.  

 

Visit http://www.bestofelectricals.com/led-lighting/led-lights to buy LED light online. The site offers numerous types of LED lights, of varied brands at reasonable prices. Huge discounts are given to the buyers and at festive season these rebates just get bigger and better. 

Why not incandescent bulb or CFLs but LEDs?

LED Bulbs

By the flow of time like everything technology is also going to more depth and details. We all are mortal. It’s an invariable, fundamental truth. What we can do, we can live a healthy life. We can make our environment clean, clear and pollution free to abolish almost all sort of risk that can affect our health.

 

Scientists are also trying to make the world pollution free. Thus they are continuously inventing various products and technology to make the world green. One of their most venerable inventions is LED lights or light emitting diode. These LEDs comes in variant size and colour.

 

LED consumes less energy and supplies more lumens. There is a small difference between watt and lumen. Watts is unit for energy consumption whereas Lumen is the light output/brightness of a lamp. Generally higher wattage/energy consumption of a lamp implies higher lumen output. So it is very important to look at the lumen when you buy a bulb.

 

Now in many respect LEDs are better than CFLs and incandescent bulb. They make a serious cut to our electricity budget than incandescent bulbs and CFLs.
