If you’ve ever heard the word “RCD” and thought it was some kind of kitchen tool – you’re not alone 😄 But in reality, an RCD is a small but powerful guardian of your electrical safety!

RCD stands for Residual Current Device (also known as a safety switch). Its main job?
👉 Protect you and your home from electric shocks and fire hazards.
As soon as it detects a current leak – click! – it instantly cuts off the power. That fast ⚡

🕰️ A Quick Look Back

RCDs aren’t a new invention. They first appeared in 1950s Germany, when engineers realized they needed extra protection in industrial electrical systems. Over time, they became the global standard – and today, they’re legally required in many installations. 📜

🔍 Fun Facts – Did You Know?

💡 An RCD can react in less than 0.1 seconds – faster than a blink of an eye!
💡 Type B RCDs can detect even the most dangerous pure DC current leaks, which most other switches completely miss.
💡 Installing an RCD is mandatory in all new home and business electrical setups across the EU 🇪🇺
💡 Without it, charging your EV can be – quite literally – life-threatening! ⚡🚫

🔢 Types of RCDs – Which One Do You Need?

RCDs come in different “flavors,” depending on the type of current they can detect:

• 🔵 Type AC – basic protection against standard AC currents
• 🔴 Type A – covers AC + pulsating DC (great for modern appliances)
• 🟠 Type F – for frequency-controlled motors and sensitive electronics
• 🟢 Type B – top-tier protection: detects everything – AC, pulsating DC, and pure DC
  👉 Type B is a must-have for EV chargers and solar systems!

🚨 Why Is This RCD Mandatory?

If you’re installing an EV charger, the law says – you need a Type B RCD. It’s not optional – it’s a technical and legal requirement.
Standard switches can’t detect pure DC faults that EV chargers may produce.
Without it, you risk electric shock, damage, or even fire. 😬🔥

That’s why SparkShare offers the complete solution – charger + RCD – compatible, tested, and ready to install. All in one place. ✔️

🛡️ Don’t take chances with electrical safety. RCDs might look small, but they can save a life – or your equipment.
💡 The right switch in the right place = peace of mind while charging.
