Product Description
What is the WAGO 221-2401 Inline Lever Nut?
The WAGO 221-2401 is a 2-conductor inline splicing connector from WAGO’s 221 Series LEVER-NUTS® line, rated 600V / 20A (UL 486C). Its slim, in-line body joins two copper conductors end to end, so it fits in tight spaces where a standard lever nut or wire nut won’t: inside conduit bodies, fixture canopies, low-voltage and control wiring, and wire extensions. Tool-free CAGE CLAMP® lever technology accepts solid, stranded and fine-stranded wire, and the clear housing lets you verify strip length and full insertion at a glance.
Key Benefits & Features
- Slim Inline Design: Joins two conductors end to end in a compact body about 8 mm wide, ideal for tight boxes, fixtures, conduit and wire extensions.
- Tool-Free Lever Connection: Lift the lever, insert the stripped wire, close the lever. No twisting, no crimping, and the conductor can be released and reused.
- All Conductor Types: Connects 20–12 AWG solid and 18–12 AWG stranded or fine-stranded copper wire, and lets you mix wire types in the same splice.
- Built-In Test Slot: Voltage can be tested at the center of the connector without opening the splice.
- Clear Housing: Transparent polycarbonate body lets you confirm strip length and full wire insertion for a reliable connection every time.
- Mounting Options: Install free-floating, or fix in place with WAGO 221-25xx mounting carriers (sold separately).
- Contractor Packaging: 2,500-piece bag sized for high volume users, electricians, maintenance teams and panel builders.

Frequently Asked Questions
Q: What wire sizes does the WAGO 221-2401 accept?
A: It accepts 20–12 AWG solid copper wire and 18–12 AWG stranded or fine-stranded copper wire. Strip each conductor to 11 mm (0.43 in).
Q: What is the 221-2401 rated for?
A: It is UL rated 600V / 20A under UL 486C and IEC rated 450V / 32A under EN 60664.
Q: Can I connect solid wire to stranded wire with the 221-2401?
A: Yes. Each side of the connector accepts solid, stranded or fine-stranded copper wire, so you can splice different wire types together.
Q: What is the difference between the 221-2401 and a standard 221 lever nut like the 221-412?
A: The 221-412 has both wire entries on the same side, like a wire nut. The 221-2401 is an inline connector: wires enter from opposite ends, making it slimmer and better suited for extending or repairing a run of wire in tight spaces.
Q: Can I test voltage without opening the connection?
A: Yes. The 221-2401 has a test slot at the center of the connector for checking voltage with a meter probe.
Q: Can the 221-2401 be mounted?
A: Yes. It snaps into WAGO 221-25xx mounting carriers, available in 1- to 5-way versions for screw mounting
