What Would Cause My Rcd To Trip

By | May 11, 2021



The RCD, or Residual Current Device, is a crucial piece of electrical safety equipment that can be found in many homes and businesses. It's designed to protect against electric shock by cutting off the power supply if it detects an electrical problem occurring in your home or business. But sometimes, despite all the security measures, the RCD can trip unexpectedly. So, what would cause your RCD to trip?

Few things are more startling than having your power cut off suddenly, leaving you in the dark. It means that something has gone wrong with your electrical supply, and usually, it's the RCD that trips in response. This vital piece of equipment serves as a protector, but it can also be extremely frustrating if it trips without warning or reason. So, what can cause your RCD to trip?

To understand why an RCD might trip, let's first look at how RCDs work. In essence, an RCD is a type of circuit breaker that works by detecting an imbalance in the flow of electric current and then triggering a cut-off switch to shut down the power supply and prevent electric shock. The RCD can also detect faults such as insulation failure, short circuits and even overloaded circuits. While they are important for safety, sometimes RCDs can be overly sensitive and trip unnecessarily. So, what would cause my RCD to trip?
