RCD Testing

An RCD, or residual current device, is a life-saving device which is designed to prevent you from getting a fatal electric shock if you touch something live, such as a bare wire. It can also provide some protection against electrical fires. RCDs offer a level of personal protection that ordinary fuses and circuit-breakers cannot provide.

What does an RCD do?

An RCD is a sensitive safety device that switches off electricity automatically if there is a fault.

An RCD is designed to protect against the risks of electrocution and fire caused by earth faults. For example, if you cut through the cable when mowing the lawn and accidentally touched the exposed live wires or a faulty appliance overheats causing electric current to flow to earth.

How does it work?

An RCD constantly monitors the electric current flowing through one or more circuits it is used to protect. If it detects electricity flowing down an unintended path, such as through a person who has touched a live part, the RCD will switch the circuit off very quickly, significantly reducing the risk of death or serious injury.

What are the main types of RCD?

RCDs can help protect you from electric shock in potentially dangerous areas like bathrooms and gardens, and there are various types of RCDs that can be used to make sure you are always as safe as possible.

Fixed RCDs

These are installed in the consumer unit (fusebox) and can provide protection to individual or groups of circuits. A fixed RCD provides the highest level of protection as it protects all the wiring and the sockets on a circuit, and any connected appliances.

Socket-Outlet RCDs

These are special socket-outlets with an RCD built into them which can be used in place of a standard socket-outlet. This type of RCD provides protection only to the person in contact with equipment, including its lead, plugged into the special socket-outlet.

Portable RCDs

These plug into any standard socket-outlet. An appliance can then be plugged into the RCD. They are useful when neither fixed nor socket-outlet RCDs are available but, as with socket-outlet RCDs, they provide protection only to the person in contact with the equipment, including its lead, plugged into the portable RCD.

Are RCDs reliable?

We’ve found that fixed RCDs are about 97% reliable. This improves if they are tested regularly. If you have fixed RCD protection, it will reduce the risk of electric shock to you and your family. It can also protect your home against the risk of fire caused by faulty wiring or appliances.

Remember – Although RCD protection reduces the risk of death or injury from electric shock it does not reduce the need to be careful. Have your wiring checked at least once every 10 years to ensure the safety of you, your family and your home. If you find a fault with your wiring, or an appliance, stop using it immediately and contact a registered electrician.

Don’t forget to test – You should test all fixed and socket RCDs about every three months. Manufacturers recommend that portable RCDs are tested every time you use them.

Beware – If you hold the test button in for a long time and the RCD does not switch off the electricity supply, then get advice from a registered electrician.

The UK standard for safety – Since July 2008 virtually all circuits in new or rewired homes have been required to include an RCD under the latest edition of BS 7671.

How do I check whether I already have fixed RCD protection?

To check if you have fixed RCD protection, go to your consumer unit and have a look to see if there is a device with a pushbutton marked ‘T’ or ‘Test’. This ‘test’ button is part of an RCD. If an RCD is fitted, there should also be a label on or near the consumer unit stating ‘test quarterly’.

Lightning Protection Survey

Crucial to the installation of any lightning protection system, lightning conductor testing should also be carried out on existing systems by skilled personnel on a regular basis, using calibrated test equipment, to ensure safety and to comply with the relevant legislation.

All requirements related to lightning protection testing are set out in the BSEN:62305 standard. Because this standard was recently updated, you may need us to assess the functionality and safety of your systems if you haven’t done so for a number of years. The standard also states that testing should be annually after the implementation of a system.

During the inspection, we’ll check:

- Corrosion of earth electrodes
- Corrosion and deterioration of conductors, connections and air-termination elements
- Condition of fixings, equipotential bonding and connections
- Earthing resistance value of your earth-termination system

A non-compliant system can mean if a lightning strike hits near or on the building, your building may not be fully protected. If you’d rather prevent injuries and financial loss, get in touch for lightning protection testing.
