An RCD or a Residual Current Device is designed to protect you from an electric shock if you were to touch something like a bare wire. It can also provide you with some level of protection against electrical fires as well, and when compared to circuit breakers, it is the much safer option. When you attach an RCD, it switches off the electricity if there so happens to be a fault. For example, if you were to accidentally cut through a cable when doing your day to day house duties and you touched the wire, you could experience a fatal electric shock.
There are a couple of different types of RCDs so it is important to understand the difference between them if you want to choose the right one for you. The fixed RCD is installed onto the actual consumer unit. This is, in most cases, the fuse box. This provides the highest level of protection and it also protects the sockets that are connected to the circuit as well. Another type would be the socket-outlet RCD. This can be used in place of a standard socket outlet and it only provides protection for the person who is touching or in contact with the lead or socket. Lastly, there is the portable RCD. This can be plugged into any socket outlet and it is great if you have either a fixed or non-fixed outlet. It should be noted that these only provide protection for the person who is in contact with the equipment, and nothing else. Studies show that RCDs are 97% reliable and this number can be improved upon if regular maintenance is carried out on the device at regular times.
When you sell or lease a property you must ensure that you have a minimum of two RCDs in your switchboard to protect your power and lighting circuits. Are you completely protected? There is a simple and easy way to find if you are. Contact Limelite Electrics today to find out more.
