A residual current device, commonly referred to as an RCD, is designed to protect you from receiving a potentially fatal electric shock should you accidentally touch a live unit including bare wires and live components of electrical appliances. An RCD may also help to provide adequate protection against fires caused by electrical faults or unsafe electrical practices. In this article we will be taking a look at the ins and outs of RCD’s and how they can protect you and your family. Let’s begin by reviewing what an RCD actually does.
What does an RCD do?
In the event of an electrical fault or shortage, an RCD will immediately switch off all electricity supplied in the household. Overall, the device is designed to protect people from the risks posed by Earth faults and electrical faults. An example of this would be if you accidentally cut through a live wire and touched the exposed wires. In theory, in this instance an RCD would cut the electricity supplied to the appliance immediately before you have a chance to electrocute yourself by touching the exposed wire.
How does an RCD work?
An RCD works by constantly monitoring the electrical current that flows through one or more different circuits. Should the device detect the electricity flowing down an improper path, it will quickly cut the electricity supply to that circuit which, in some cases, can make the difference between minor and fatal injuries.
The main types of RCD
There are a few different types of RCD’s that can be used in your home.
This type of RCD is regarded as one of the safest types as it provides protection for a whole circuit and the appliances that are involved. It is generally installed into a consumer unit where it will monitor the electrical current flowing through the circuit. It is also one of the most popular used by homeowners today.
Socket-outlet RCD’s are special sockets that incorporate the design of an RCD into their setting in order to monitor the electrical supply to individual appliances. However, although safe, this type of RCD will only provide protection to the individual who comes in contact with the appliance or equipment as well as its lead.
This particular type of RCD, as you can tell by the name, is portable and can be plugged into any switch or socket in order to provide adequate protection to the person using an individual piece of equipment. Like socket-outlet RCD’s they only provide protection to the person in contact with the appliance as well as the equipment’s lead. For this reason, fixed RCD’s are highly recommended in any standard home.
If you’d like to find out more about RCD’s, here is a short clip telling you how to use them, how you can check whether or not your consumer box currently has an RCD installed and how they can protect you from fatal consequences.
