What Causes Your Circuit Breaker to Burst

Circuit Breakers are electrical parts designed to protect us against the risks of electric shock and our houses in opposition to fire and different types of damage that can be caused by electrical faults. Every circuit breaker in your electrical switchboard often protects one or more associated circuits in opposition to overload, quick circuit and earth leakage.

With a view to understand what causes a circuit breaker to burst (or more commonly known as journey), we first need to understand what a circuit is and what the terms overload, brief circuit and earth leakage mean.

What Are Circuits?

The electrical installations in our houses are divided into electrically separated segments known as circuits. Every circuit provides electricity to equipment in a very well defined and particular group. All the light fittings and light switches are discovered on one circuit known as the lighting circuit. Air-conditioners, heating and air flow equipment are grouped on one other circuit known because the HVAC circuit. And final but not least, socket retailers are grouped on a circuit known as the ability circuit.

Each circuit is made up of cables, switches, connections and other electrical equipment designed to carry only the utmost electrical current specified by the manufacturer. When exposed to current exceeding this maximum, the electrical part might break down, melt or catch on fire. Circuit breakers have been launched to make sure this doesn’t occur by disconnecting the electricity provide when the electrical present that flows exceeds the maximum capacity that the circuit elements can handle.

Overloaded Circuits – The Most important Reason a Circuit Breaker Journeys

Have a look round your house in any respect the socket outlets. How many home equipment are plugged into each socket outlet? Likelihood is you’ve got obtained more than the circuit is designed for. Our increasing use of electrical and electronic units places more pressure on our electrical installations every single day – generally to the purpose the place the quantity of electricity we use exceeds the quantity that the circuit can safely give us without overheating or getting damaged. When this happens, the circuit breaker in your switchboard will disconnect the circuit from the electrical supply.

Short Circuits – When Things Go Really Improper

Whether or not you’re digging within the garden for the nice new flower box, or drilling a hole within the wall to put up that pretty family image, every time you make adjustments to the house you run the risk of damaging electrical cables hid behind partitions or within the soil. Whenever you drill a gap through a cable or cut it with a spade, direct contact happens between the person wires within the cable. This is known as a short circuit. Electrical cables aren’t designed to withstand the current flowing in such a short circuit situation. In cases corresponding to this, the brief-circuit protection mechanism in the circuit breaker disconnects the electricity provide to ensure that the cable doesn’t soften or catch fire.

Earth Leakage Currents

Generally known as ground fault present or residual current, this is electricity that flows from the electrical set up to the ground or different conductive materials of the house. Electrical systems are designed to pass present between the live conductors of the installation. When home equipment like kettles, refrigerators and washing machines turn out to be faulty, they will permit current to flow through their metal parts into your body and down to the ground. This is a harmful situation known as an earth leakage. Certain types of circuit breakers known as Residual Present Units or Ground Fault Current Interrupters journey after they detect this current flowing to the ground to protect you from electric shock.

In summary, there are only three very simple reasons why circuit breakers trip:

1.) A circuit is overloaded, i.e. there are more gadgets linked to it than the circuit can actually accommodate.

2.) A brief-circuit is present. Although less likely than an overload, a cable or different part of the fixed wiring may be damaged. You may want a qualified electrician to repair this fault and make your property safe again.

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