Key Benefits of Proper RCD Selection

The letter on the device matters more than ever:

  • Type Coverage: A, B and F stocked, not just AC.
  • Selective Options: S-types keep whole boards from tripping.
  • Board-Matched: Elucian units drop into their system.

Frequently Asked Questions

What they can see: Type A reads pulsed DC from modern electronics, Type F adds high-frequency awareness for inverter drives and Type B covers smooth DC from EV chargers and solar, each stated per device.

Purpose: 30mA is personal shock protection at final circuits, 100mA time delay S-types sit upstream for fire protection and selectivity.

Waits politely: the upstream RCD delays so the downstream 30mA unit clears the fault first, keeping the rest of the installation live.

Smooth DC risk: EV charging and inverter equipment can blind ordinary RCDs, so Type B like FuseBox’s 63A unit is specified where they connect.

Point-of-use protection: the 13A spur adds 30mA Type A protection to a single appliance circuit without touching the board.

Stay in-system: Click’s units are made for Elucian consumer units, with cross-brand fitting a compliance risk, per listing.
