What Causes Your Circuit Breaker to Burst

Circuit Breakers are electrical parts designed to protect us in opposition to the risks of electric shock and our homes towards fire and different types of damage that may be caused by electrical faults. Each circuit breaker in your electrical switchboard usually protects one or more associated circuits towards overload, brief circuit and earth leakage.

In order to understand what causes a circuit breaker to burst (or more commonly known as journey), we first must understand what a circuit is and what the terms overload, short circuit and earth leakage mean.

What Are Circuits?

The electrical installations in our properties are divided into electrically separated segments known as circuits. Each circuit provides electricity to equipment in a very well defined and specific group. All of the light fittings and light switches are discovered on one circuit known as the lighting circuit. Air-conditioners, heating and ventilation equipment are grouped on one other circuit known because the HVAC circuit. And final however not least, socket shops are grouped on a circuit known as the facility circuit.

Each circuit is made up of cables, switches, connections and different electrical equipment designed to hold only the utmost electrical current specified by the manufacturer. When exposed to present exceeding this most, the electrical element may break down, melt or catch on fire. Circuit breakers were introduced to make sure this doesn’t happen by disconnecting the electricity supply when the electrical present that flows exceeds the maximum capacity that the circuit elements can handle.

Overloaded Circuits – The Foremost Reason a Circuit Breaker Journeys

Have a look around your house in any respect the socket outlets. How many appliances are plugged into each socket outlet? Chances are high you’ve received more than the circuit is designed for. Our increasing use of electrical and digital gadgets puts more pressure on our electrical installations day by day – generally to the purpose the place the amount of electricity we use exceeds the quantity that the circuit can safely give us without overheating or getting damaged. When this occurs, the circuit breaker in your switchboard will disconnect the circuit from the electrical supply.

Short Circuits – When Things Go Really Incorrect

Whether you are digging within the backyard for the good new flower box, or drilling a gap in the wall to put up that beautiful family picture, every time you make adjustments to the house you run the risk of damaging electrical cables concealed behind partitions or in the soil. Whenever you drill a hole by means of a cable or cut it with a spade, direct contact occurs between the individual wires within the cable. This is known as a short circuit. Electrical cables aren’t designed to withstand the present flowing in such a short circuit situation. In cases similar to this, the brief-circuit protection mechanism in the circuit breaker disconnects the electricity provide to ensure that the cable does not soften or catch fire.

Earth Leakage Currents

Typically known as ground fault current or residual current, this is electricity that flows from the electrical installation to the ground or different conductive supplies of the house. Electrical systems are designed to pass current between the live conductors of the installation. When home equipment like kettles, fridges and washing machines turn out to be faulty, they will allow current to flow by way of their metal parts into your body and down to the ground. This is a harmful situation known as an earth leakage. Sure types of circuit breakers known as Residual Current Devices or Ground Fault Present Interrupters trip when they detect this present flowing to the ground to protect you from electric shock.

In abstract, there are only 3 very simple reasons why circuit breakers journey:

1.) A circuit is overloaded, i.e. there are more units related to it than the circuit can really accommodate.

2.) A brief-circuit is present. Though less likely than an overload, a cable or other part of the fixed wiring may be damaged. You’ll want a certified electrician to repair this fault and make your private home safe again.

3.) An appliance is causing an earth leakage current to flow. Of all the eventualities, this is by far the most likely cause. Appliances grow to be defective all the time, and the result is a circuit breaker that keeps tripping.
