How to use Wago 222 connectors

Helpful video reference. We use John Ward's (jwflame) video "Wago 222 Wire Connectors vs Other Unbranded Type" as the reference here. John cuts open both genuine 222s and unbranded copies side by side, shows the spring contact quality, and stress-tests them. It is one of the most useful comparisons available for anyone wondering whether the cheaper alternatives are good enough for mains wiring (they are not).

1. Choose the right 222 variant

The Wago 222 series comes in three port counts:

• 222-412 - 2 ports, for joining two conductors end to end.
• 222-413 - 3 ports, the most common in lighting circuits where you join live, neutral and earth from two cables.
• 222-415 - 5 ports, used where several conductors meet in a junction box.

Count the conductors before opening the packaging. If you need to join four conductors, two 3-way connectors (one per polarity pair) will work cleanly. A 5-way with two empty ports is acceptable - an empty port poses no risk provided the lever stays closed.

2. Strip the conductor to the right length

The strip length for Wago 222 connectors is 10 to 11 mm. Most 222 connectors have a small gauge symbol or a strip length marker on the housing. Use a proper wire stripper set to the conductor size rather than a knife, particularly on the small 1.0 mm and 1.5 mm conductors in lighting cables where nicking a strand makes the connection less reliable.

Solid conductors from twin-and-earth cable and fine-stranded conductors both seat correctly, but do not try to insert a flexible (multistrand) conductor without first twisting the strands together firmly. Loose strands fold back outside the entry hole and the connection will fail the tug test.

3. Open the lever

Each port on a Wago 222 has its own small grey lever. Lift the lever on the port you are about to load - it pivots back through roughly 90 degrees and stays open, exposing the conductor entry hole. You do not need to apply much force; if the lever feels stiff on a new connector, warm conditions usually help.

Do not try to insert a conductor into a closed port. Forcing a wire past the spring with the lever down risks bending the contact and the connection will be unreliable.

4. Insert the conductor fully

Push the stripped end of the conductor straight into the entry hole in a single smooth movement. Push until the conductor stops against the back wall of the housing - the full stripped length should disappear inside the connector with no bare copper showing outside. If the conductor stops short, check the strip length and try again; a 9 mm strip on a connector requiring 11 mm will not reach the contact properly.

5. Close the lever

Press the lever back down until it sits flat and flush with the housing. The spring contact inside grips the conductor as the lever closes. You should feel slight resistance as the lever seats - not a hard click like a Wago 221, but a definite point where the lever locks closed. A lever that springs back open has not engaged fully; check the conductor is seated correctly and try again.

6. Carry out a tug test on every conductor

Before closing the junction box lid, pull each conductor firmly and steadily. A properly seated conductor in a genuine Wago 222 will not come free. Any that pull out must be reseated: open the lever, push the conductor fully home, and close again.

John Ward's video makes the difference clear: genuine 222 connectors resist the pull test with authority, while unbranded copies release conductors at much lower forces. For mains wiring, the tug test is not optional - it is the only check you can make before closing the box.

When to call us

Replacing a connector in a ceiling rose or junction box is well within a careful homeowner's reach provided the circuit is dead and the cable condition is good. The moment you open a box and find burnt conductors, no earth, or colours you cannot identify, that is a job for a qualified electrician. Small call-out jobs in Sandwich are priced at £10 per 10 minutes.
