WAGO 221 Lever Nuts 90pc Compact Splicing Connector Assortment

In this review the WAGO 221 Lever Nuts 90pc assortment is judged as a practical kit for electricians, DIYers and anyone who regularly makes wire splices. The single biggest reason to buy is reliability combined with speed: these genuine WAGO LEVER NUTS let users connect solid, stranded and flexible copper conductors far faster than twisting wire nuts while keeping the connection visible and inspectable. The included hard case and mixed conductor counts make it a convenient, grab-and-go set for job sites and home projects.

Key Features

• Mixed conductor assortment: Includes 25x 221-2401, 25x 221-412, 25x 221-413 and 15x 221-415 so you have 2-, 3- and 5-conductor options on hand without buying separate packs.
• Broad wire compatibility: Terminates 24-12 AWG for the 221-41x series and 20-12 AWG for the 221-2401, covering the most common residential and light commercial wiring sizes.
• Transparent housing: The clear body allows visual inspection for proper strip length and full wire insertion, reducing rework and safety concerns.
• Lever operation: Tool-free levers speed up repetitive connections and make it easy to secure stranded and flexible wire types without twisting.
• UL Listed components: Genuine WAGO parts with UL listing offer reassurance when used in compliant installations.

Who It's For

This kit is ideal for professional electricians, contractors and serious DIYers who want consistent, repeatable splices that save time compared with traditional wire nuts. The different conductor counts suit lighting circuits, switch loops and multi-conductor splices commonly found in renovations and new installs.

It is less necessary for someone who only performs a couple of occasional home fixes and prefers buying single small packs, or for projects requiring exotic conductor sizes outside the listed AWG ranges. Users who must follow a specific connector brand required by inspection should confirm approvals before replacing existing hardware.

Pros & Cons

• Easy and fast to use, especially compared with wire nuts for repeated connections.
• High perceived quality and reliable clamping action thanks to genuine WAGO components.
