Review on WAGO 221 Series Splicing Connectors with Compact Case: 25pc Wire Connectors Bundle - Includes 10x 221-412, 10x 221-413, 5x 221-415 by Fredrick Edwards

Of course, this work can be done cheaper, but it put my mind at ease. I installed a ceiling fan last night and used it in place of the nuts that came with it. It costs a few bucks to make sure I'm only doing the job I'm doing right a few times a year. They also allowed me to cut some of the wires, which helped me install larger outlets with USB ports built in. I would highly recommend and plan on buying more next time they go on sale or when they run out.
