    Key Types of RCDs

    • Type A RCDs:
      Detects both AC residual currents and pulsating DC residual currents. Type A RCDs are suitable for circuits with modern electronic loads, such as LED lighting, appliances with variable-speed drives, and EV chargers. They provide enhanced safety for systems with non-linear loads.
    • Type B RCDs:
      Designed to detect all forms of residual currents, including AC, pulsating DC, and pure DC currents. Type B RCDs are ideal for circuits in renewable energy systems, three-phase inverters, and EV chargers where pure DC currents may be present.
    Pole Configurations
    • 2-Pole RCDs:
      These protect single-phase circuits by monitoring both the live and neutral conductors. They are commonly used in residential and small commercial installations for applications like lighting and socket circuits.
    • 4-Pole RCDs:
      These protect three-phase systems with or without a neutral connection. They are suitable for industrial and large commercial setups, such as motor controls, HVAC systems, and machinery.
    Key Features
    • Earth Leakage Protection: Provides safety by disconnecting the circuit during earth leakage faults, preventing electric shocks and potential fires.
    • High Sensitivity: 30mA RCDs are standard for personal protection, ensuring compliance with safety standards.
    • Durable Construction: Built with robust materials to ensure reliability in demanding environments.
    • Standards Compliance: Fully compliant with IEC 61008 and BS EN 61008, ensuring safety and performance.
    • Wide Application Range: Available in multiple configurations to suit residential, commercial, and industrial needs.
    Applications
    • Residential Systems:
      Safeguards circuits for lighting, power sockets, and appliances. Ideal for kitchens, bathrooms, and other areas with higher risks of electrical shock.
    • Commercial Buildings:
      Protects lighting, HVAC, and critical power circuits in offices, schools, and retail spaces.
    • Industrial Installations:
      Ensures the safety of high-load circuits, motors, and machinery in factories and warehouses.
    • Renewable Energy Systems:
      Essential for solar PV installations, battery storage, and EV charging systems, particularly when pure DC currents are involved (Type B RCDs).
    Why Choose Live Electrical RCDs?
    • Enhanced Safety: Provides reliable protection against earth leakage faults for people and property.
    • Versatile Configurations: Offers Type A and Type B RCDs with 2-pole and 4-pole options to meet diverse requirements.
    • Future-Proof Design: Type B RCDs ensure compatibility with renewable energy systems and modern electronic equipment.

    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 £200 + VAT (double our standard carriage-paid order value of £100 + 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 £100 + VAT:
    Orders above £100 + 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 £200 + 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 £200 + 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.
