SKU CH-2P9C-F63F2 MPN 221-612

Lever-actuated splicing connectors join solid or stranded copper wires from 20 to 10 AWG without tools, tape or twisting

  • ColorBlack
  • Tool-free lever actuation speeds up wiring
  • Reusable design allows repeated opening without integrity loss
  • Transparent housing enables visual confirmation of wire insertion
  • Handles solid, stranded and flexible copper from 20–10 AWG
  • UL 486C listed for 600 V building wire and 1000 V signs

Tool-free splicing connector

This WAGO 221 Series lever-actuated splicing connector joins two solid, stranded or fine-stranded copper conductors from 20 to 10 AWG without twisting or taping. The transparent housing lets you verify strip length and full insertion at a glance. Each connector is rated for 30 A and up to 600 V on building wire or 1000 V on signs and luminaires. A box contains 50 pieces.

Ideal for quick, reusable wire joins

Installers who need fast, vibration-proof splices in lighting, HVAC, appliance or RV wiring will appreciate the lever action that requires no special tools. The connector can be opened and closed repeatedly without losing connection integrity. It is not suited for applications that demand more than two conductors per connector or wire gauges outside the 20–10 AWG range.

Two-conductor, 20–10 AWG capacity

The single specification that decides fit is the two-conductor capacity covering solid, stranded and fine-stranded copper from 20 to 10 AWG. If your project requires three or more conductors in one block, or conductors thicker than 10 AWG, this model will not work.

Questions about this item

Do the 221-612 Lever-NUTS generate any heat or noise when they carry 30 A continuously?

These are passive spring-pressure connectors with no moving parts or electronics, so they produce no noise and negligible heat at their 30 A UL rating.

What wire types and sizes must I already have to use these 2-conductor connectors?

You need solid, stranded or fine-stranded copper conductors between 20 AWG and 10 AWG; the transparent housing lets you verify strip length and full insertion.

Will the 221-612 work alongside older twist-on wire nuts already installed in the same junction box?

Yes — the lever-actuated design accepts the same 20–10 AWG copper wires used with traditional twist-on connectors, so you can mix them in the same box without compatibility issues.
