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

🔒 Quality Brands – Authorised UK Stockist

We are an authorised distributor for:

  • Hager
  • FuseBox
  • Niglon

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.

Supplier Lead Time & Availability

This item may be sourced from our supplier before dispatch.
The lead time shown is an estimate only and is based on the usual supplier timeframe. It is subject to supplier availability and is not a guaranteed delivery date.
We do not have a live supplier stock feed, so supplier stock can change without notice.
Delivery timers and courier estimates apply once the item is available for dispatch.
If the item is unavailable, we will contact you with the available options, including waiting for stock, choosing an alternative product, cancellation, or a refund for the unavailable item.
This does not affect your statutory rights.
