FAQs

What does RCD stand for?

RCD stands for Residual Current Device.

What is the purpose of a 30mA RCD?

A 30mA RCD is designed to protect against electric shock by quickly disconnecting the power supply if a leakage current to earth is detected.

How often should I test the RCD?

Test the RCD monthly using the test button, and perform a full functional test annually.

What type of protection does a Type A RCD offer?

A Type A RCD offers protection against pulsating DC residual currents.

Can I install an RCD myself?

Installation should be carried out by a qualified electrician to ensure compliance with safety standards and regulations.
