A safety switch is essentially a device that very quickly switches-off the electricity in case any electrical fault is detected. In effect, it reduces the risk of injury & death caused by contact with electricity. Current day safety switches are very different from the ones used even up until a decade ago. Today, it’s mandatory to have these installed in buildings where any kind of electrical addition or upgrade has taken place.

Apart from this, safety switches are also needed for power outlets that that supply electricity to mobile homes like caravans etc. It’s not mandatory to have these safety switches in older homes; however, the recommendation is that you should consider getting them installed. It is one of the most effective ways to protect your family & yourself from electric shock.

ELCBs or Earth-leakage circuit breakers are safety devices used to prevent shock in electrical fixtures which have high Earth impedance. The current installations use the circuit breakers that directly detect leakage in current. Here are some features of an ELCB:

RCDs or RCCBs are essentially modern electrical wiring devices which quickly disconnect a circuit if they detect that there is an imbalance in the current between the energized conductor/s & the return conductor. They are designed to immediately switch-off the electricity supply when the electricity leaking to earth is detected to be at harmful levels. These devices offer very high levels of protection from electric shock.

Voltage Earth-leakage circuit breakers were first introduced around 60 years ago, while the current ELCBs were launched only around 40 years ago. For a very long time, voltage-operated ELCBs & differential current-operated ELCBs were both called ELCBs; this was because it was a far easier term to remember. However, as expected, this common name caused a significant amount of confusion within the electrical industry.

If someone accidently used the wrong one in a particular application, the installations may not get the kind of protection it needed. It was to eliminate this confusion that the International Electrotechnical Commission decided that the differential current-operated ELCBs will be termed as RCD (residual current devices). Any current that’s over & above the load current is referred to as the residual current.

ELCBs have a number of disadvantages such as:

Today the RCD is preferred means of providing effective shock protection. The term is also most widely used across the globe.

Home automation is the latest trend in electrical installations; it allows you the functionality to control various devices in your home, via a mobile device from any location (in your city or even from across the world). It’s true that the term home automation could be used for various programmable devices such as sprinkler systems and thermostats.

However, home automation is much more than that, and it encompasses a number of things in a home including:

All of these are connected to a network that can be remotely controlled. From the perspective of home security, this includes fixtures such as the alarm system in your home, as well as the windows, doors, smoke detectors, locks, the CCTV cameras as well as the other sensors that are connected to it.

Even up until the recent past, it was only commercial systems and high-end homes that had automated centrally-controlled systems. Typically, these included only the heating & cooling systems, lighting systems and they hardly ever provided anything more than just the standard controls, monitoring functions as well as scheduling actions. In addition, these were accessible only from certain control points from within the very same building.

While this was a definite convenience and advantage, home automation takes this concept and technology one step further; and is popularly called the – ‘ Internet of Things’. In this type of system, everything has a specific IP address that can be accessed and monitored remotely.

Smart devices and various smart appliances are the most obvious things that get connected to the LAN via Wi-Fi or Ethernet. However, it’s possible to incorporate electrical outlets and light switches into your home automation network.

In addition to the convenience factor, the energy efficiency factor is what makes home automation such an attractive option. While modern appliances provide convenience and comfort, many of them are also power guzzlers; home automation systems also address this issue. Thermostats help monitor the heating and cooling system in your home; similarly the lighting systems can also be programmed and set for various target temperatures.

This helps keep energy usage at the minimum levels during the times when you aren’t really going to be using them. In fact this scheduling can be broken down at a more micro level to distinguish between the seasons of the year and the weekends etc., in some instances. If required, ‘macros’ can also be programmed into the system and these can be controlled remotely as required.

In fact, you can add settings – like “coming home” etc. that can activate various appliances, equipment and installations at the tap of your smartphone and you can have the opposite set as a “leaving home’ event. This ensures you use only as much energy as required, which adds to the overall energy efficiency of your home.

If you are considering getting smart automation solutions for your home, it’s important that you get experienced and credible electricians to handle the job for you. We at Allround Electricals are a company that has been operating in this space for a number of years and know what it takes to provide our customers with the kind of solutions they need.
