Wago Connectors Explained: Which One to Use Where
Lever connectors versus push-fit, when to use enclosures, and which Wago connectors are worth carrying in the van.
Wago Connectors Explained
Lever connectors have become the standard way most electricians join conductors, largely replacing older methods such as twisting conductors together and taping the joint, or fitting old-style strip connectors. They are quick to fit, quick to check, and quick to take apart again if a fault needs tracing.
This guide covers the difference between lever and push-fit connectors, when an enclosure is needed, and which connectors are worth keeping in stock. For the wider toolkit these sit alongside, see our electrician tools guide.
Lever vs Push-Fit Connectors
Lever Connectors
Wago's lever connectors accept both solid and stranded conductors, which is what makes them so flexible on site. Opening and closing the lever by hand also means a connection can be checked, reworked or extended without cutting anything away.
Push-Fit Connectors
Push-fit connectors are simpler again: push the conductor in and it grips. They are for solid or rigid conductors only, so they suit straightforward solid-cable joints rather than flexible cable, and they cost less than the lever range.
- ✓Lever connectors: solid and stranded conductors, reworkable by hand
- ✓Push-fit connectors: solid or rigid conductors only, cheaper per unit
- ✓Both are faster to fit and check than twisting and taping a joint
When You Need an Enclosure
Purpose-made enclosures, boxes designed around the connector shape, are used where a connection needs to be suitable for limited access after installation. A junction hidden in a ceiling void or a boxed-in stud wall is the typical example: once the plasterboard is up, that joint is not getting checked again without disruption.
Match the enclosure to the connector
Enclosures are sized around specific connector footprints, so buy them as a matched pair rather than assuming any box will fit any connector.
On the Job: Luminaires and Van Stock
Lever connectors turn up everywhere: joining a luminaire's flex to the fixed wiring, extending a circuit at a junction, or making a temporary connection during fault-finding. Because the range is used so consistently across a career, it is one of the first things worth stocking properly in the van rather than buying piecemeal per job.
For the rest of a well-stocked van, including consumables and the racking to keep them organised, see our electrician van setup guide.
Connector Stock Worth Carrying
A sensible starting stock covers a lever connector assortment, a box of push-fit connectors for straightforward solid joints, and a run of matching enclosures.
