The practice of electrical safety is crucial in every domestic, commercial, and industrial property. Observing electrical safety can outright prevent any cases of accidents, injuries, or fatalities. Additionally, the use of different electrical safety devices can immediately avoid any types of property or equipment damage.

Some electrical safety devices found on properties are fuses, ground fault circuit interrupters, arc fault circuit breakers, surge protectors, and many more. While these devices can effectively regulate the current flow and react to any anomaly on the electric system, one device that offers great benefits for property owners is a residual-current device.

What is a residual-current device?

A residual-current device is a life-saving sensitive device that prevents any person from getting a fatal electric shock if ever you touch a live bare wire. This device can also provide some protection against electrical fires of properties. Unlike ordinary fuses and circuit-breakers, the presence of a residual-current device helps in offering a specific level of direct personal protection.

One problem that typically occurs in electrical systems and devices is an electric fault. An electrical fault is an abnormal electric condition caused by equipment failures, weather conditions, human errors, and smokes of fires. The occurrences of electrical faults usually contribute to the interruption to electric flows, damages to the equipment, and injuries or death of humans. Fortunately, the presence of a residual-current device helps in automatically switching off the current flow whenever faults occur, which ultimately saves lives, equipment, and properties.

How does the device work with other electrical devices?

To ensure round-the-clock functionality, the residual-current device will constantly monitor the electrical current that is flowing through one or more circuits. Once electricity flows down an unusual or unintended path, then the device will immediately switch the circuit off. Usually, a residual-current device can switch off the power in 0.3 of a second to prevent further effects of electrical fault. 

For it to work effectively, a residual-current device must be installed with other electrical devices. Fixed residual-current devices are usually installed in the consumer unit or fuse box so that they can provide protection one or more circuits. Alternatively, other types of residual-current devices can be either built into or plugged into a standard socket-outlet.

Why is it important in different applications?

One importance of a residual-current device in domestic, commercial, and industrial applications is that it reduces the risk of fires to properties and lives. This device will immediately prevent the electrical current from flowing through the circuits once an electrical fault is detected. By the time the current is cut off, the electrical current will not have any way of overloading and straining the equipment and devices anymore.

Another importance of a residual-current device in various applications is that it can save lives. Electrocution happens when a person touches a live wire. The effects of electrocution will solely depend on how much electric current has flowed through the wire. With a residual-current device, the fatal effects of electrocution will be minimised right away as it cuts the flow in a fraction of second. This device also prevents the transfer of the energy from electrons to your body, protecting you from gaining life-threatening injuries. Installing residual-current devices around your property will help you gain the mentioned life- and property-saving benefits. To have them installed on your property, just call us at Light-On Electrical. We can accomplish all types of electrical, air conditioning, and refrigeration needs for strata, commercial, industrial, and residential properties.

The presence of air conditioning units has changed the way we live or work. These units have given us an environment with temperatures our body can fully endure. And for them to work efficiently every day, they must be maintained regularly to prevent any sudden damages and unexpected repairs. After all, you do not want your unit to be damaged on the same day when the outside temperature starts to rise.

For your own good, you can follow these preventative maintenance tips to prevent sudden air conditioning unit breakdowns and damages. Some of these maintenance tips might need some help from professionals.

Inspect Unit Connections

One of the most common problems in air conditioning units is their wiring and electrical connections. There will be times when some of these connections might have been loosened up due to a long time of use. Some wires might have already been damaged or worn out without you noticing, which may result in random power loss during air conditioning operations. You must have these connections checked with professionals so that they can fix or replace them right away.

Replace Dirty Air Filters

Filters that are dirty and clogged with dust and other elements can block normal airflow and reduce the efficiency of your air conditioning unit. And with the absence of normal airflow, your air may carry dirt directly into your evaporator coil and affect its heat-absorbing capacity. For proper maintenance, you must replace your dirty filter with a clean one so that your energy consumption will be lowered by a huge percentage. If you have a reusable filter, then you must clean it regularly. Mostly, filters must be maintained every month or two during the cooling season.

Clean Air Conditioner Coils

Your unit’s evaporator coil and condenser coil can both accumulate dirt and other outdoor elements over their entire service life. With a clean filter, any soiling action on the coils will be minimised. However, you must remember that they still collect dirt over time. As dirt thickens, your coils may reduce sufficient airflow and ultimately lose the ability to absorb heat. To prevent these situations from happening, you must check and clean your coils every year. You must also clean the area around the coil, remove any debris, and trim the foliage back at least 2 feet to allow adequate airflow.

Assess Fans and Drain Line

Checking your fan blades is a must to maintain adequate performance. Just like your air filters, your fan blades can also get coated with grime due to their exposure to smog and outside pollution. Once the grime starts to thicken, expect your fan speed to slow down and your motor to be strained. Fortunately, cleaning the blades can easily prevent airflow problems.

Aside from fans, you must also check your drain line since it may be clogged with algae and other elements. For proper maintenance, you must drain the excess moisture by flushing it from time to time with a small amount of bleach. If you have spotted some algae or mould, then you must remove them through a basic wet or dry vacuum cleaner. 

Check for Worn Parts

Some components of air conditioning units may have already been worn due to a long time of use. Any damages that may occur on components like the belt, pulley, electronic controls, refrigerant line, and thermostats may cause your system to shut down unexpectedly. Alternatively, there were some instances where the unit cannot produce cold air anymore. When you have spotted these problems in your unit, you must contact some service technician for help. If the damages are already severe, then you may want to start shopping for a new unit.

All these preventative maintenance tips must be done to ensure the optimal performance of your air conditioning unit. For more information about preventative maintenance of air conditioning units, then give us a call now at Light-On Electrical.
