What is a Twin RCD board used for?

Twin RCD boards split the load across two RCD-protected banks, providing discrimination and limiting nuisance tripping in domestic and light commercial installs.

What’s the difference between 63A, 80A, and 100A RCDs?

This refers to the RCD’s rated current capacity. Choose based on your expected total load - 100A is commonly used for full-board protection, while 63A or 80A is used when circuits are split.

Do these boards include surge protection?

Only “/SP” models include built-in Type 2 SPD. Surge protection is mandatory in most new builds and recommended for EV or solar installs.

How many usable ways do I need?

Each “usable way” represents space for one circuit breaker. Choose a model based on the number of circuits you’re protecting - leaving space for future additions if needed.

Are these boards compliant with Amendment 2?

Yes - all boards are 18th Edition compliant, and SPD-equipped variants help meet surge protection requirements for most domestic installs.
