The RCD rating you should use depends on the requirements of the circuit you are protecting. For general purpose circuits in homes, a 30mA RCD is commonly recommended. In certain specific situations or for specific equipment, a higher or lower rating may be appropriate. Consulting with a qualified electrician for advice tailored to your specific needs is recommended.

Will a rcd detect live to neutral fault?

No, a Residual Current Device (RCD) will not detect a live-to-neutral fault because this type of fault does not result in a current imbalance that the RCD can detect. An RCD is designed to detect imbalances between the live and return current in a circuit, such as those caused by a leakage current to ground.


What kind of fuse need to use for 240V outlet?

For a 240V outlet, you should use a fuse that is rated for 240V. The fuse's amperage rating should match the amp rating of the circuit and be appropriate for the connected devices. It's important to use the correct type and rating of fuse to protect the circuit from overloading and electrical hazards.


Does RCD works on DC system?

No, Residual Current Devices (RCDs) are designed to work on AC systems only. They are used to protect against electric shock by monitoring the current balance between the live and neutral conductors. In a DC system, different protection measures are necessary since the current flows continuously in one direction.


What difference in current amperage makes an RCD trip?

RCD stands - Residual Current Device. Normally It measures current on phase & neutral and if there is any change or difference (Should be Phase I - Neutral I = Zero) even 30mAmps RCD trips to break the circuit to avaoid any damages to equipments as well as human beings. Its same as ELECB / RCCB.


How do you decide the rating of a switch for wiring?

Switch rating should match or be greater than the rating for the protecting breaker.

How many mega ohms to trip rcd?

The specific megohm value to trip a Residual Current Device (RCD) can vary based on the RCD's rating and application. Typically, an insulation resistance test may require readings of 1 megohm or higher to ensure safe operation, but RCDs themselves trip based on differential current, not insulation resistance. If the leakage current exceeds the RCD's rated sensitivity (commonly 30 mA for household devices), it will trip regardless of insulation resistance. Always consult the manufacturer's specifications for precise requirements.
