Residual Current Devices (RCDs) ensure electrical safety by detecting fault currents and disconnecting the supply. They protect against:

  • Fault Protection: Trips when fault current flows to earth.
  • Additional Protection: Trips at 30mA or below to prevent electric shock.
  • Fire Protection: Trips at 300mA or below to reduce fire risks.

RCDs monitor circuit leakage and trip when imbalances are detected, offering more sensitivity than circuit breakers.

Types of RCDs

  1. Type AC: For basic protection against AC currents.
  2. Type A: Handles pulsating DC currents up to 6mA, ideal for electronics.
  3. Type F: Suitable for frequency-controlled appliances like washing machines.
  4. Type B: Handles advanced DC currents, perfect for industrial and EV systems.

Selecting the Right RCD
Choose an RCD type based on connected equipment. Modern devices, like EV chargers and LED drivers, often require advanced RCDs like Type A, F, or B. Consult BS 7671:2018 standards and manufacturer guidelines to ensure compliance.

Key Considerations
RCDs should match the installation’s requirements. Regular testing and proper enclosure are essential for reliability. Always assess potential DC fault currents to select the appropriate type.

Stay safe by selecting the right RCD for your installation.

    Delivery Policy
    Free Next-Day Delivery Over £75 + VAT:
    Orders above £75 + VAT qualify for free next-day delivery via DPD for in-stock items. While we strive for timely dispatch, we recommend placing orders early to avoid potential delays. Once dispatched, unexpected issues may arise despite the courier’s efforts.

    Orders Below £150 + VAT:
    To keep costs manageable, we dispatch your order once all items are ready, including products with longer lead times.

    Need items faster? You can pay for an additional delivery service to receive in-stock items sooner. Simply email us with your order details, and we’ll send you a payment link for the extra delivery cost.

    Orders Above £150 + VAT:
    For larger orders, we can split delivery at no extra cost. In-stock items will be sent immediately, with the remaining items dispatched once available.
    Dispatch Times
    Items with Lead Times (e.g., 1–3 Working Days):
    This means we need to source the product from our supplier before sending it to you. The estimated dispatch time is displayed on each product page.

    Out of Stock at Supplier:
    If an item is unavailable at the supplier, we will contact you promptly. You’ll have the option to choose an alternative product or request a full refund.
