WAGO 221 Series 78pc Compact Splicing Wire Connectors - Reusable

Our review of this WAGO 221 Series 78pc assortment finds it best for electricians, DIYers, and installers who need a compact, reusable way to make secure splices without twisting or taping. The single biggest reason to buy is the lever-actuated, twist-free connection that works reliably with solid, stranded, and flexible copper wires from 24-12 AWG, making common wiring tasks faster and less fatiguing than traditional wire nuts.

Key Features

• Lever-actuated design: The open-and-close levers provide a twist-free connection that saves time and reduces wrist strain during repetitive wiring tasks.
• Reusable connectors: Each connector can be opened and closed repeatedly, making the set useful for temporary work, testing, and reconfigurations without damaging the conductor.
• Wide wire compatibility: The 221 Series accommodates solid, stranded, and flexible copper wires from 24-12 AWG, covering most household and light commercial needs.
• High ratings and approvals: Rated to 600V (up to 1000V in signs and fixtures) and 20 A, and carrying UL, cUL, RoHS, REACH, and CE certifications for global compliance.
• Assortment case: The heavy-duty organizer includes 34 of the 2-port, 26 of the 3-port, and 18 of the 5-port connectors for a balanced kit that stays accessible on the job.
• Money-back guarantee: Backed by a 12-month money-back guarantee reflecting the manufacturer's long history with spring pressure technology.

Who It's For

The kit is ideal for residential electricians, handymen, and serious DIYers who value speed and reliability in routine splicing, lighting, and fixture work; the compact size and lever action are especially helpful where space is tight. Professionals who need repeatable temporary connections for testing or troubleshooting will also appreciate the reusability.

Those who work exclusively with very large conductors beyond 12 AWG, or who require specialized insulated crimp or soldered terminations for high-vibration industrial machinery, should consider other connector types tailored for those applications.

Pros & Cons

Pros

• Easy, tool-free lever operation that speeds up wiring and reduces hand fatigue.
• Works with solid and stranded copper conductors and holds connections securely without vibration loosening.
• Organized assortment with multiple port counts covers common wiring scenarios.
