    Why Choose Electrical4Less for Your RCDs?

    At Electrical4Less, we stock a comprehensive range of Residual Current Devices (RCDs) that protect against electric shock, fire risk & equipment damage. Whether you’re installing in a home, commercial site or EV system, we have the right solution — in stock & ready to ship.

    🔌 What Does an RCD Do?

    RCDs monitor circuit leakage and trip when an electrical imbalance is detected — reacting faster and more sensitivelythan standard breakers.

    They offer three key types of protection:

    • Fault protection – trips when fault current flows to earth
    • Additional protection – trips at 30mA or lower to protect people
    • Fire protection – trips at 100mA or 300mA to reduce fire risks

    ⚙️ RCD Types Explained

    We supply all major RCD types, including:

    • Type AC – for basic protection against AC currents
    • Type A – detects pulsating DC up to 6mA, ideal for modern electronics
    • Type F – suitable for appliances with variable frequency (e.g. heat pumps, washing machines)
    • Type B – advanced DC detection for EVs, solar, and industrial use

    💡 Modern devices often require Type A, F, or B. Always check the equipment and BS 7671:2018 guidelines before selecting.

    📏 Current Ratings & Sensitivities

    • 30mA – for personal protection (domestic or additional protection)
    • 100mA / 300mA – for fire protection and commercial equipment safety
    • 2 pole & 4 pole options – for single or three-phase installs

    Next Day Delivery

    Cut-Off Time and Order Information
    To ensure your order qualifies for next day delivery, please place your order by 3:00 PM. This is subject to all items being available on the shelf at the time of your order. For orders where the total value exceeds £150 + VAT (double our standard carriage-paid order value of £75 + VAT), we are happy to split the delivery into two shipments if some items are needed urgently and others are not immediately available. If you have any questions or need further assistance, feel free to reach out to us via WhatsApp for live support. We’re here to help!

    In Stock 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.

    Backorder Delivery Policy

    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.
