RCD sockets (Residual Current Device) are life-saving sockets that protect individuals and equipment from faults by automatically cutting the power supply. They safeguard equipment against overheating, earth faults, and electrocution dangers in case a bare wire is touched. These sockets, equipped with RCD, are alternatives to standard socket outlets and ensure a safe environment.
Why are RCDs favored over standard fuses or circuit breakers?
In simple words, RCDs provide a contrasting and high levels piece of mind that ensures protecting you and your family from electric shocks and fires resulting from faulty equipment or wiring. Furthermore, they are considered 97% reliable; however, care must be taken to stay safe.
What are the types of RCD sockets?
They are classified into the following types.
Fixed RCDs provide the highest level of protection for the people, circuits, connected wiring, and sockets usually installed in consumer units or fuse boxes.
Used as an alternative to common socket outlets, these RCDs provide protection for individuals who encounter the equipment.
These portable RCDs work similarly to the socket outlet RCDs that protect the person in contact with the device. They plug into a common socket outlet where the appliance is plugged into RCDs.
Active RCDs, also called Non-Latching RCDs, isolate, and protect the circuits from power cuts and faults and remain active till reset manually. They are primarily found in rotary machines like gardens and power tools.
Passive RCDs, or Latching RCDs, are designed to trip out and isolate protected circuits if there is power loss. These devices do not trip in the event of a power cut, making them perfect for freezers and fridges. They are also ideal for protecting remote environments.
Where are RCD sockets used?
RCD sockets primarily function to protect against electric shock in environments such as:
- Bathrooms
- Gardens
- Construction Sites
- Workshops
- Garages, or where there is a risk of exposure to bare wires.
