WAGO wire connectors: Loved by millions of customers worldwide!

Instead of screws, our 221 series use the spring pressure connection technology that we invented and is loved worldwide to connect electrical conductors.

This is because, as an electrician, splicing connectors with screw connections have several potential sources of error: an excessively tightened screw can damage the conductor and permanently change the cross-section. Screw connections that aren't properly tightened could lead to high contact resistance, impermissible heating of the connector, and (in the worst case) even a fire. Moreover, temperature fluctuations and vibrations can loosen the connection over the long term, even when the screw-type connectors are properly tightened.

All these problems you do not have with our splicing connectors.

Frequently Asked Questions

WAGO 222 vs. 221

The WAGO 221 is characterized by several advantages compared to the older WAGO 222. Firstly, the 221 has a much more compact design - it is 40% smaller than the 222, which saves space in crowded junction boxes. The 221's levers are designed so that they can be opened and closed with less effort. While the WAGO 222 series has only one test point, the WAGO 221 has two test slots per connection. Another advantage of the WAGO 221 is its transparent design, which makes it easier to position the wire correctly. Compared to the 221, the 222 also accepts thinner wire gauges (up to 28 AWG, 0.08 - 4 mm²).

What is a splicing connector or What is a Wago connector?

A splicing connector makes it easier to connect stripped solid, stranded and fine-stranded conductors from 0.14 to 6 mm² (24 ... 10 AWG). A splicing connector, such as the Wago 221 splicing connectors, is designed to accommodate the stripped ends of two or more wires. Once the stripped wires are inserted into the connector, the internal spring pressure connection secures the conductors without the need for soldering or screwing. This type of connection ensures a safe and reliable electrical connection that can be quickly rewired at any time. Users also avoid mistakes that could lead to fire in the worst case scenario. The levers on the connector ensure faster installation. The spring pressure connection eliminates the need for maintenance.

Are Wago connectors legal?

Yes, Wago splicing connectors with a cross-sectional area of 4 mm² comply with SANS 10142 CLAUSE 4 and Hazardous Areas (Ex) requirements for splicing and connecting conductors, making them a legal and safe choice.

Are Wago connectors as good as wire nuts?

Although Wago connectors are more expensive per unit than wire nuts, their ease of use and reliability compensate for the higher costs. They enable faster, safer and maintenance-free installation.

Can you use WAGO on solid wire?

WAGO's 221 Series Splicing Connectors enable the splicing of solid, stranded and fine-stranded conductors from 0.14 to 6 mm² (24 ... 10 AWG).

Can you use WAGO connectors in house wiring?

Yes, they are designed for use in residential buildings and can also be adapted for industrial applications on DIN rails with appropriate mounts.

Can you leave WAGO connectors exposed?

With WAGO's Gelbox, WAGO connectors can also be used outdoors. They offer protection up to protection class IPX8. This protection class means that the connectors are completely sealed against water and can also be permanently submerged under water. Conventional potting compounds also meet protection class IPX8, for example polyurethanes or silicones. The special feature of the Gelbox is that it protects the electrical installation exactly where it matters - at the connection points - without having to irrevocably seal junction boxes.

How do I join 2 electrical cables together?

There are many ways to make a cable connection, such as crimp and solder connections. But the quickest, easiest, safest and most maintenance-friendly method is to use connecting terminals with spring pressure connection technology and levers, such as our WAGO 221.

How do you join wires without soldering?

The best way is with our WAGO's 221 Series wire connectors with lever. Simply strip the conductor, open the lever, insert the conductor, close the lever. Done.

What are the best connectors for joining wires?

When it comes to connecting solid, stranded and fine-stranded conductors from 0.14 to 6 mm² (24 ... 10 AWG), we can recommend our WAGO 221 with a clear conscience, just as millions of customers worldwide do.
