The installation of RCD safety switches in your distribution board or your meter box are only a few of those small yet important investments that you can do in your home. Furthermore, testing these switches will not only save you time and money but it will also offer long-term protection for your family and property. It will help reduce your risks of facing serious injury and even death brought on by electric-related accidents. Without the protection of an RCD switch, even the most common daily activity could turn deadly without any warning. Because of this, it is extremely important to conduct an RCD testing for safety purposes.
What Is An RCD Safety Switch?
A residual current device or a safety switch cuts off your home’s power in case a problem in the electrical system is detected. Electrical problems are sometimes difficult to identify because they hidden in most cases. Various kinds of electrical accidents can happen in an instant and the fastest way to protect you and your family is through RCDs.
How Does It Work?
The Residual current device safety switches check the amount of power that flows in the Active and Neutral wires, which supplies electricity to a certain circuit or home appliance. The amount of electrical current flowing in both of them should be equal. An imbalance takes place if there is an earth leakage, an accident with the equipment, or a defect in the circuit. The RCD safety switch detects this problem and cuts off the power to prevent damage or injury from happening. The device disconnects in under 20 milliseconds after it detects a problem. That is how fast it should work once you conduct an RCD testing.
It prevents the electricity from flowing through the body of the person who contacts with it down to the earth. The aforementioned response time of the RCD device is also faster than the vital aspect of the cardiac cycle and that means it helps reduce the risk of serious injury or death. It also lowers the possibility of an electrical fire that may stem from faulty appliances, tools, and wirings.
What Are The Types?
There are four types of RCD safety switches.
Meterbox Mounted RCD – located near circuit breakers or the distribution board of the house.
Combination RCD – protects the appliances and electrical circuits. It prevents probable electrocution and a great alternative when it comes to retrofitting into existing meterboxes with little to no space to spare.
Portable RCD – connects itself to an extension lead or power board. It protects the circuits of the appliances linked to it. They are ideal options for individuals who regularly use electrical appliances and power tools outside, in an area not protected by a power point RCD or a meterbox RCD.
Powerpoint RCD – are connected to a power point and comes with a distinguishable feature such as the test button on the face plate. It needs to be connected to the first power point following the meter box. They are designed to provide added protection to electrical appliances like workshops and bathrooms.
Do You Have An RCD Safety Switch Installed At Home?
The installation of the RCD safety switch at the source of the power and lighting circuits is mandated by law. Since 2000, new homes are required have at least two RCD Safety Switches as part of the electrical installation. Meanwhile, those who live in homes that were built before the year 2000 can expect to see only one RCD installed, which will only safeguard one power circuit. This cannot provide an assurance that you and your property will have complete protection since other lighting circuits would be left unguarded.
