Product Information
Full details
This Selectric RCD Switch Socket (Passive) is designed for users who need reliable protection against earth faults, especially in situations where a power interruption should not cause the RCD to trip. Its key benefit is maintaining power to connected appliances during outages, making it ideal for essential equipment like refrigerators and freezers. However, it is not recommended for use with certain power tools or lawnmowers due to its latching mechanism. This socket provides protection against electric shocks and fires, complying with BS7288 and BS1363 standards, and features double pole switching, a 13A 240V rating, and a sensitive 30mA tripping current with a rapid response time of under 30ms.

FAQs
What is a passive/latching RCD?
A passive or latching RCD remains in its closed state after being set and will only trip if a hazardous earth fault occurs. Importantly, it stays latched even if the power supply is interrupted, making it suitable for essential appliances.
When should I use this RCD socket?
This RCD socket is ideal for appliances that need to maintain power through electrical interruptions, such as refrigerators, freezers, fish tanks, and battery chargers. It also provides essential safety protection for general home appliances and gardening equipment.
Why is it not recommended for power tools?
The passive/latching design means it won't automatically disconnect if power is lost or if there's a fault that requires immediate shutdown for safety. For tools like lawnmowers, a non-latching RCD is generally preferred for immediate safety disconnection.
How do I test the RCD?
Use the integrated test button. Pressing it should cause the RCD to trip, disconnecting power. This should be done regularly (e.g., monthly) to ensure it is functioning correctly.
What does 30mA tripping current mean?
It means the RCD is designed to detect a fault current of 30 milliamps. This level is generally considered the threshold for causing harm to humans, thus providing protection against electric shock.
What is the tripping time?
The tripping time is less than 30 milliseconds (<30ms). This indicates a very rapid response to a fault, minimizing the duration of exposure to a dangerous electrical condition.
What standards does this RCD socket comply with?
It complies with BS7288 and BS1363 standards, which are safety and performance benchmarks for electrical accessories in the UK.
Troubleshooting
RCD trips frequently without apparent fault
Check the connected appliance for faults. Reduce the number of connected appliances. Ensure the RCD is suitable for the total load. If the issue persists, contact a qualified electrician.
RCD does not trip when the test button is pressed
The RCD may be faulty. Do not use the socket and contact a qualified electrician for inspection or replacement.
Power is lost to the connected appliance after a power cut
The RCD is functioning as intended by tripping due to the power interruption, or a fault occurred. Manually reset the RCD switch. If it trips again immediately, there may be a fault with the connected appliance or the circuit.
Device remains off after a power outage and manual reset
Ensure the power supply to the RCD socket is restored. Check the connected appliance itself. If the RCD still will not reset, there may be a persistent fault, and an electrician should be consulted.
Pros and Cons
Pros
- Maintains power during outages for essential equipment.
- Provides robust protection against electric shocks and fires.
- Complies with relevant safety standards (BS7288, BS1363).
- Fast tripping time (<30ms) for quick fault response.
- Double pole switching for more comprehensive isolation.
- Built-in test button for easy safety verification.
Cons
- Not suitable for use with power tools or lawnmowers.
- Requires manual resetting after a trip or power loss.
- Passive operation might not be ideal for all applications requiring immediate disconnection on power failure.
Setup, Compatibility & Care
Setup: This RCD socket replaces a standard socket outlet. Installation should be performed by a qualified electrician to ensure compliance with electrical safety regulations. Ensure the power supply is isolated before beginning installation.
Compatibility: The socket is compatible with standard UK electrical systems (13A 240V). It complies with BS7283 and BS1363 standards. It is designed for use with appliances where continuous power is beneficial, but not for high-demand power tools that require immediate shutdown on fault.
Care: Regularly test the RCD using the integrated test button (monthly is recommended). Keep the socket clean and dry. Use a slightly damp cloth to wipe down the surface; avoid abrasive cleaners or solvents. Ensure the area around the socket remains clear of obstructions.
