Consumer units, also known as fuse boxes or distribution boards, are electrical enclosures that house circuit breakers or fuses to control and distribute electricity within a building or residential property. They are a crucial part of the electrical system, providing protection against electrical faults and allowing for the safe distribution of electricity to various circuits and appliances.

The main purpose of a consumer unit is to safeguard electrical circuits from overloading, short circuits, and electrical faults that could lead to fires or other hazards. The consumer unit acts as a central point where the electrical supply from the utility company enters the building and is then distributed to different circuits throughout the property.

### **Consumer Unit Features**

It is important to note that the specific design and components of consumer units can vary depending on local electrical codes and regulations. In some regions, more advanced consumer units with enhanced safety features such as arc fault detection may be required. Listed below are the most common features found in consumer units. 

- **Main Switch**: The main switch serves as the primary control point for the electrical supply to the property. It allows complete isolation of the system, enabling safe shutdown during emergencies or maintenance.
- [**Residual Current Circuit Breakers**](https://uk.rs-online.com/web/c/fuses-circuit-breakers/circuit-breakers/rccbs/)** (RCCBs)**: RCCBs are protective devices designed to prevent electric shock. They continuously monitor the flow of current and disconnect the supply if they detect an imbalance—such as current leaking to earth—indicating a potential fault or hazard.
- [**Circuit Breakers**](https://uk.rs-online.com/web/c/fuses-circuit-breakers/circuit-breakers/ ): These devices provide protection against overloads and short circuits. They automatically trip or switch off the circuit when the current exceeds a safe limit or when a fault occurs.
- [**Fuses**](https://uk.rs-online.com/web/c/fuses-circuit-breakers/fuses/ ): Older consumer units may use fuses instead of circuit breakers. A fuse contains a thin wire that melts when the current exceeds a specific threshold, breaking the circuit to prevent overcurrent damage. However, fuses are largely replaced by MCBs or RCBOs in contemporary systems due to their resettable nature and improved reliability.
- **Circuit Labels**: Consumer units typically have labels or identification markers for each circuit, indicating which areas or appliances they supply power to. This makes it easier to identify and isolate specific circuits when necessary.

Consumer units can be found in a range of materials, sizes, and capacities to suit almost any electrical installation. Consumer unit capacity is determined by the number of ways, popular choices being [4-Way](https://uk.rs-online.com/web/c/fuses-circuit-breakers/circuit-breakers/consumer-units/?if=4-way-consumer-units), [6-Way](https://uk.rs-online.com/web/c/fuses-circuit-breakers/circuit-breakers/consumer-units/?if=6-way-consumer-units) and [10-Way](https://uk.rs-online.com/web/c/fuses-circuit-breakers/circuit-breakers/consumer-units/?if=10-way-consumer-units). Getting the right IP rating is also important, for standard residential usage IP20 to [IP30](https://uk.rs-online.com/web/c/fuses-circuit-breakers/circuit-breakers/consumer-units/?selectedNavigation=attributes.International_Protection_Rating=IP30) is often sufficient, whilst for industrial usage, [IP-65 Consumer Units](https://uk.rs-online.com/web/c/fuses-circuit-breakers/circuit-breakers/consumer-units/?if=ip65-consumer-units) offer high-level protection against dust and moisture.
