Wago Boxes Explained — everything you need to know about compact junction boxes designed for Wago 221, 222, and 2773 connectors.
Electricians often refer to these small adaptable enclosures as Wago Boxes, but the name covers more than just one product line. This guide explains their purpose, history, compatibility, and why they have become the preferred choice for maintenance-free electrical connections.
Wago Boxes Explained – How They Work
A Wago Box is a compact junction box made to house Wago lever or push-in connectors. It provides mechanical protection, strain relief, and compliance with BS 5733 for maintenance-free joints.
These boxes are ideal for lighting circuits, ceiling voids, or anywhere a standard junction box would not fit. They are quick to install and suitable for both solid and flexible conductors.
Wago Connector Compatibility
Modern Wago Boxes work with several connector ranges, giving electricians the flexibility to choose the right option for each job.
- Wago 221 Series – compact transparent body with levers for easy inspection and reuse
- Wago 222 Series – classic orange-lever design, ideal for solid or stranded cable
- Wago 2773 Series – push-in connectors that save time and space in junctions
Each series fits securely inside Wago Boxes, creating clean, reliable connections that meet UK wiring standards.
Wago and Connexbox – The Evolution
The first Wago Box design came from a partnership between Wago and a UK manufacturer that later became Connexbox.
Today, Wago focuses on connector development, while Connexbox continues to improve the enclosure design, adding flexible entry points and better internal layouts.
Both remain compatible and widely used by professional electricians for domestic and commercial work.
Regulation and Safety Compliance
When used with approved Wago connectors, these junction boxes comply with BS 5733 and BS 7671 (18th Edition Wiring Regulations).
They are suitable for inaccessible locations such as under floors, behind ceilings, and inside wall cavities.
Combining Wago Boxes with 221, 222, or 2773 connectors ensures safe electrical continuity and long-term reliability.
