The 222 series are much tighter, and require more force to lift.
Those and the indent style EMT fittings. I have had to cut every one of them off. They seem to never let go.
Funny world; I love them both.
Caution. The Wago 221 series are only rated for a maximum of 450 volts. Others rated for 600 volts but I'm old school and still prefer pressure connectors ( wire nuts ).Have used them when replacing a lot of garbage short life Bodine ballasts. Home Depot is almost as bad as Amazon in supplying pertinent information.
With 2 test standards, 1 suitable for 600Vac @ 60min intervals, Lever-Nuts seem superior to most twist on's, inner tube, or tape.
I have one under the hood of my truck. Squirrels or their friends nibbled on some wires. Only left short stubs to re-connect. I've been riding with a Wago on the circuit for the windshield washer sprayer for a couple of years, and it still works (knocking on wood). Wago is more or less hanging in mid-air holding onto the wires.
I never like the too generous IEC ratings on contactors. Rather use the UL rating that appears to be always lower. If you go with the lower ampere ratings from UL contactors & starters will run cooler & last longer. I bet that most cheap fellow electricians will not use WAGO'S because they cost a lot more. I'm old school and still prefer pressure connectors ( ya wire nuts ) . I have at least 5 boxes of wire nuts in my garage from three different companies that some say pre twisting is not necessary but others suggest that you pretwist . I always strip insulation around 7/8" then pre twist with heavy side cutters, trim the ends even, hand tighten the wire nut then use heavy side cutters to tighten wire nut and at least halve a turn of insulation then wrap it with quality electrical tape. Have went back to Motors that I installed twenty years later and every wire nut was in great shape. I bet this method is superior to wagos especially in higher temperature locations &/wires running at full capacity . With 5/8 to 3/4" of twisted copper conductors sure that connection has a lower resistance then the small contact area that wagos provide.
Nothing wrong with using traditional tools that work for the job.
I never use the cheap wire nuts that come with luminares. Most do not have a spiral metal spring. My brother in law was a salesman for a large refrigeration/air conditioning supply house that had over a dozen stores. They had a young guy whose main job was to bag small amounts of wire nuts, ty rabs, hardware, fuses, plumbing fitting FS etc into little bags. They were high priced but the lowest quantity material that they made a ton of money from. Saw some of the Wago knockoffs on the web. Scary .First company that I worked for got feed up with so many poor performing products that only purchased name brands such as T&B, Hubbell, Shawmut fuses, etc. Learned to only order flat washers by the pound from industrial hardware supply houses because they were always beefy and not like the paper thin garbage from cheating china.
