What Does A Fuseboard Do?

Your fuseboard — also called a consumer unit — is the heart of your electrical system. It manages and protects every circuit in your home or workplace, helping prevent electrical hazards before they become serious.

Here’s a quick look at what’s inside:

• Circuit Breakers (MCBs)
  These protect individual circuits (like lights or sockets) by automatically cutting power if too much current flows — preventing overheating and reducing fire risk.
  
  
• Residual Current Devices (RCDs)
  RCDs cut off electricity in milliseconds if they detect a fault or risk of electric shock, offering vital protection for people.
  
  
• Surge Protection Devices (SPDs)
  Now standard in many installations, SPDs defend your electronics from voltage spikes caused by surges or lightning strikes.
  
  
• Main Switch
  This lets you shut off all electricity to the property when needed — essential for safety and emergency work.

Is Your Fuseboard Up to Date?

An outdated or overloaded fuseboard can not only reduce efficiency but also pose a serious safety risk. Here are a few signs you might need an upgrade:

• Frequent tripping or flickering lights
  
  
• No RCD protection present
  
  
• A rewireable fuse system instead of breakers
  
  
• Planning major electrical work or adding new circuits (like EV chargers, extensions, or outdoor power)
  
  
• Your consumer unit looks aged or isn’t labelled clearly

Remember:  A tripping fuse board is a safety measure.  Don’t ignore it—take action to ensure your home and family remain safe.
