Fuse Board Installations: Upgrading Your Electrical Safety

When it comes to your property's electrical safety, few upgrades are as crucial as a fuse board installation. Also known as a consumer unit or fuse box, this essential component plays a central role in protecting your home from electrical hazards.

In this article, we'll explore the importance of fuse board installations, the difference between various terms like fuse board, fuse box, and consumer unit, and why upgrading your consumer unit is a smart choice.

What's the Difference Between a Fuse Board, Fuse Box, and Consumer Unit?

The majority of the time people are referring to the same thing, therefore these terms are often used interchangeably, but there are distinctions and here's why:

  • Fuse Box: An older term that refers to the same component as a fuse board. Fuse boxes used fuses to protect circuits and appliances.

  • Consumer Unit: The modern term for the fuse board or fuse box. Consumer units contain circuit breakers and RCDs (Residual Current Devices) for enhanced protection.

What's the Difference Between RCDs and MCBs?

Understanding the role of RCDs and MCBs is essential in grasping the importance of a fuse board upgrade:

  • RCD (Residual Current Device): RCDs monitor the electrical current flowing through circuits. They quickly trip, cutting off the power supply if they detect a fault, such as a live wire touching a metal surface or a person receiving an electric shock. RCDs are crucial for preventing electric shocks and fire hazards.

  • MCB (Miniature Circuit Breaker): MCBs are designed to protect circuits from overloads and short circuits. They automatically switch off the electricity supply if a circuit draws too much current or if there's a short circuit. MCBs prevent wiring and appliances from overheating and causing fires.

What Are the Benefits of Upgrading a Consumer Unit?

Upgrading your consumer unit comes with several significant advantages:

  • Enhanced Safety: Modern consumer units come equipped with RCDs, providing superior protection against electric shocks and fire hazards.

  • Reduced Risk of Overloading: MCBs in the new unit ensure that circuits are protected from overloads, preventing overheating and potential fires.

  • Compatibility: A new consumer unit can accommodate additional circuits, making it suitable for modern electrical demands.

  • Convenience: Circuit breakers in modern consumer units are easily reset, offering a convenient solution in the event of a tripped circuit.

  • Compliance: An upgraded consumer unit ensures compliance with current electrical regulations, giving you peace of mind regarding safety and legal requirements.

  • Added Property Value: A modern consumer unit can add value to your property, making it more appealing to potential buyers or renters.

Do I Need an Electrician to Change a Consumer Unit/Fuse Box?

In a word, yes. Changing a Consumer Unit, also known as a fuse board or consumer unit, is not a DIY project. It involves intricate electrical work and adherence to safety regulations.

A licensed electrician possesses the expertise to ensure a seamless transition, complying with safety standards and local regulations. Attempting this task without professional knowledge could lead to serious safety risks.

Does a New Consumer Unit Require Building Regulations?

Yes, a new consumer unit installation typically falls under building regulations. Electrical work is subject to strict regulations to ensure safety and compliance. An electrician will not only replace your old unit but will also ensure that the new installation meets all necessary building regulations. This includes considerations such as adequate circuit protection, RCD protection, and proper wiring.


Whether you refer to them as a fuse board, fuse box or consumer units, the correct installation is a critical component of your home's electrical safety. It's crucial to understand the importance of hiring a qualified electrician for this task to ensure compliance with safety regulations.

Upgrading your consumer unit offers enhanced safety, reduced risk of overloads, and increased convenience. Moreover, it ensures compliance with modern electrical standards, adds value to your property, and most importantly, provides you and your family with peace of mind.
