RCD is an abbreviation for Residual Current Device, a potential lifesaving designed to prevent you from getting a fatal electric shock if you touch something live. For example, if you touch a live wire, the electricity will flow through an unintended path (your body). That change will be detected by the RCD, which will trip and turn off the circuit, dramatically reducing the risk of a life-threatening injury. RCDs commonly protect you from electric shock in potentially dangerous areas, such as bathrooms and gardens. Therefore, RCDs are quite sensitive.
RCDs also provide protection against fires caused by earth faults. If the earth leak is detected, the RCD will trip and turn the circuit off before the leakage becomes dangerous.
There are various types of RCDs available online for next day delivery.
Residual Current Device (RCDs) is used to help save lives by preventing electric shocks. RCDs are designed to detect dangers of electric shock causing them to trip and turn off the circuit. RCDs reduce the risk of life threatening injury.
What trips an RCDs?
RCBs trip when there is a fault in the electrical circuit. If your RCD trips frequently, there is a damage in your electrical appliance. This helps you to identify the hazards to prevent electrocution and provide maximum protection.
What does RCDs not protect against?
RCDs are designed to protect against earth leakage currents. However, will not be able to protect against current overload and short circuits. MCDs would be used to protect against overloads and short circuits or RCBOs for protection of both current overload and earth leakage currents.
Can RCDs protect against fire?
RCDs are designed to protect against earth leakage currents. Earth leakage currents can cause fires. Therefore, RCDs are extremely effective and can protect against fire.
Are RCDs required?
RCDs are designed to protect your home and yourself from potential hazards. RCDs are used to identify faults in the electrical circuits to prevent life threatening injury and the hazard of a fire.
How do you know if an RCDs is faulty?
It is important to install RCDs with the correct current rating. If an RCD has a low currenting rating, it can cause it to trip repeatedly.
How to test RCDs?
RCDs must be tested regularly to ensure the device is operating. RCDs are extremely easy to test and are fitted with a test button. Press the test button and release to test if an electricity supply is connected. The test button will identify if the device is operating correctly.
