How to Avoid Short Circuits

short circuitFaulty electrical systems such as short circuits and power surges may lead to fire, damages, injuries, and worse, deaths. The culprit to blame could be wiring deterioration which naturally occurs over time. What’s more, electrical systems are being overloaded these days, with the proliferation of home appliances. But one of the main reasons could also be our knowledge in electrical connections in our household. In this article, we will learn more about short circuits and how to avoid them.

What is a Short Circuit?

By technical definition, a short circuit is an “accidental path of low resistance which passes an abnormally high amount of current.” It exists whenever the resistance of a circuit or the resistance of a part of a circuit drops in value to almost zero ohms.

In lay man’s explanation, on the other hand, a short circuit is a consequence of broken insulation, improper wiring or overloading as it leads to a heating effect and results in fire breakouts.

Safeguards for Consideration

        1.       Check the proper size of circuit breakers in electric panels.

There is an electrical code which controls a number of circuits in the house connected to the main circuit breaker installed. The capacity of the breaker depends on the load size (e.g. outlets, microwave, dryer and vacuum). This load size is the point where the individual circuits base the current when they start to get power and determine the proper wire size to feed the circuit.

A short circuit results if the breaker exceeds the current the device is supposed to open up to. In this note, it is important to install electrical equipment according to the circuit voltage, current strength and correct wiring. One good suggestion is to avoid using multi-plug sockets.

          2.       Check old and current installations.short circuit philippines

If you have been living in the same house for decades and have not checked the electric installation, it is advisable to have it inspected by professionals. This is to ensure that all wirings are still safe and are adaptive to the new demands of your appliances and electrical requirement.

Modifications to the system done by nonprofessionals (relatives, friends or neighbors) might not assure the required level of safety and protection of your devices. Also conduct regular for current operations to eliminate perils.

          3.       Install fuses.

Fuses are protective devices placed in the circuit to quickly interrupt the flow of current when it exceeds the values for which it has been designed. It functions as the stopper of the flow of electricity when two or more conductors with a different phase or polarity come into contact in an electric installation. Resistance is formed thereby impeding the short circuit’s occurrence in the current.

        4.       Install magneto-thermal switches.

Just like fuses, magneto-thermal switches also prevent power surges. They are used to prevent short circuits as it monitors the current load continuously. They interrupt the electricity supply when it rises above the predetermined upper limit, thus removing fire risks. What happens next is that the circuit will be placed into fault and clamped at the max load.
