WAGO 221 Series 75pc Compact Splicing Wire Connectors - Reusable Lever

In this review the WAGO 221 Series 75pc compact splicing kit is judged as a practical, time-saving solution for anyone doing household or light commercial wiring. The kit is ideal for DIYers, electricians testing circuits, and installers who want a secure connection without twisting or tape; the single biggest reason to buy is the lever-actuated, reusable design that speeds work and reduces hand strain while maintaining reliable contact. The reviewer found the assortment of 2-, 3- and 5-port connectors handy for mixed jobs and appreciated that these WAGO lever nuts handle solid, stranded, and flexible copper wire up to the stated AWG range.

Key Features

• Lever-actuated reuse: The lever mechanism lets users open and close connectors repeatedly, making them ideal for testing, rework, and temporary setups without sacrificing a secure termination.
• Twist-free, tape-free connection: Eliminates the need for traditional twisting or tape, reducing installation time and wrist fatigue on repetitive jobs.
• Wide compatibility: Accepts solid, stranded, and flexible copper wires and covers the common 24-12 AWG range for most residential and light commercial wiring tasks.
• High voltage and current rating: Rated for up to 600V in general use (and up to 1000V in signs and fixtures) with a 20 A current rating, supporting a broad set of applications safely.
• Assortment convenience: The heavy-duty case includes 25 each of 2-port 221-412, 3-port 221-413, and 5-port 221-415, keeping connectors organized and ready for varied jobs.
• Global standards: Manufactured with UL, cUL, RoHS, REACH, and CE approvals, offering assurance of compliance and consistent quality.

Who It's For

The WAGO 221 Series kit suits homeowners tackling wiring projects, electricians who need quick test-friendly terminations, and installers who prefer compact alternatives to bulky wire nuts. Its reusability and lever action are especially helpful for repetitive tasks, troubleshooting, and temporary connections during system changes.

Those who need extremely high current capacity, specialized connectors for aluminum wire, or a color-coded system for complex control panels may want a different, more specific connector type. For standard copper wiring up to 20 A, this kit is a sensible, space-saving choice.

Pros & Cons

Pros

• Easy and fast to use, significantly reducing installation time compared with twisting and taping.
• Reusable lever design makes testing and reconfiguration straightforward without damaging wires.
• Compact footprint and secure hold; customers report they do not vibrate loose like wire nuts.

Cons
