Review on 🔌 WAGO 221 LEVER-NUTS 32pc Wire Splicing Connector Assortment. Includes (14x) 221-412, (10x) 221-413, (8x) 221-415 by Nicholas Peters

These lever nuts are more expensive than wire nuts but offer significant time savings. Because they use a clamp arm to attach to wires, they're easy to reuse and detach when needed. The process involves stripping a half-inch wire, inserting it into a connector, and clamping it in place. Connections are easy to check and adjust if necessary. They also save a lot of space in the junction box and do not require as many pigtails as other splicing methods. Great for DIYers.
