WAGO Cable Connectors

Why more and more electricians have turned to WAGO connectors

What are electrical cable connectors?

Electrical cable connectors, also referred to as terminals, are wiring accessories used to safely and securely connect or join multiple wires together onto a circuit. They feature an insulated housing that can safely carry the wires’ current.

What are WAGO cable connectors?

Wago connectors are an increasingly popular wire connector choice for electrical contractors. This is largely due to their world-leading spring clamp connection technology that ensures a simplified and secure wire connection. Wago was the first company to switch from traditional tools and screws to the now popularly used spring pressure technology.

They are a hassle-free wiring solution that enables you to join two or more pieces of electrical wires together quickly and easily, whilst benefiting from vibration-resistance and maintenance-free connections. We will delve further into more of the benefits of Wago’s cable connectors later in the blog.

Types of WAGO connectors

Wago developed three main types of wire connectors consisting of two types of spring clamp connectors, and push-in wire connectors.

Wago 222-series

The WAGO 222-series is the classic and original Wago cable connector introduced in 2003. It is reusable and utilises a compact cage lever which ensures ease of use as you simply flip the lever to secure or release a connection. It can connect solid, stranded, and fine-stranded conductors without any hassle. In addition, it can be used in a range of applications such as in lighting fixtures, sun blinds, awnings, doors, gate controls, inter phones, pumps, loudspeakers, etc.

• The Wago 222-412 32A 2 Way Compact Lever Operated Cable Splicing Connector Terminal Block is a 2-way terminal block with a maximum current rating of 32A and voltage rating of 400V. It is designed for connecting solid, stranded, and fine-stranded conductors without the need for additional tools. The solid and stranded conductor sizes range from 0.08mm²-2.5mm² whilst the fine stranded conductor size ranges from 0.08mm²-4mm².

In terms of construction, it utilises a simple button-operated lever clamp system that ensures a fast, hassle-free, and secure termination of cables. It also features two test ports for easy testing of all standard test probes and a reduced operating force for easy splice termination. It also has a length indicator on the casing which details the correct length the wire should be stripped to. Finally, thanks to its compact housing profile, it is ideal for use in installations where spacing may be restricted, or where you may need to maximise wiring space in restricted environments such as in junction boxes.

We also stock the 3 way and 5 way versions of the Wago 222 Compact Lever Operated Cable Splicing Connector Terminal Blocks:

• The Wago 222-413 32A 3 Way Compact Lever Operated Cable Splicing Connector Terminal Block is a 3 way terminal block with a required cable stripped length of 9 to 10mm. It also has solid and stranded conductor sizes ranging from 0.08mm²-2.5mm² whilst the fine stranded conductor size ranges from 0.08mm²-4mm².
• The Wago 222-415 32A 5 Way Compact Lever Operated Cable Splicing Connector Terminal Block is a 5 way terminal block with solid and stranded conductor sizes ranging from 0.08mm²-2.5mm² whilst the fine stranded conductor size ranges from 0.08mm²-4mm².

How do you use Wago cable connectors?

1. Use a wire cutter to remove the appropriate level of insulation.
2. Lift the lever connector and then insert the wire.
3. Once the wire is inserted, shut the lever connector.
4. Finally, ensure you test the voltage found on the top of the compact wire connector.
