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
