So the last couple of house I did I bought exactly what was in the picture below. My point here? Is that every town near me has changed the required to using the block connectors for pigtails - no exceptions for the purple nuts. When done wrong you get burnt aluminum improperly connected to the copper. When done properly the house is just as safe as an all copper house. In addition - Probably the most common - potentially dangerous thing - for homeowners or beginning electrician is updating aluminum connectors with copper pigtails. I am guessing it cuts into profit margin on other things. You would have to open up your ceiling to fix a "bad spring" and I have never heard of this ever ever happening. the largest producer of canned lights use blocks. Probably be one of the last I use.Īnyone that has any safety concerns or fear that these might go out. But I think its just because I have a big bucket of nuts. That being said I just wired another basement last week and used nuts haha.
I have bought many a house where I open up an outlet and was like "how did this even work?" and then notice the melted plastic and black marks. Having 3+ wires without proper contact is a much much larger issue in my opinion. If the spring did have issues like the backstabs. Joe-Average usually doesn't get his wires appropriately twisted when combining 3+ 12g wires. If messing with 12g multiply this times 10. They are definitely safer to use in outlet boxes for the average person and they are easier. I am sure some stores do but most don't and if they do they are on the bottom shelf - you know like the very very bottom tray. I have no idea why the big boxes don't sell these. Let's face it if Joe-Average homeowner saw these first at big blue/orange/green and they were readily available, they would certainly be used more. But I think there are cheaper push-ins available and I don't think cost is the main factor.īecause the big box stores haven't made selling these a priority. They are WAY more expensive than buying a bucket of mixed twist nuts. I buy the expensive clear Wago brand lever nuts.
GREEN WIRE NUTS PROFESSIONAL
(Not that the lever nuts themselves are high risk, but that any changes to the highly rehearsed and tuned techniques of a professional create risks.)
But if a professional is highly adept at doing installations with twist nuts, can do them quickly, effortlessly, and knows the result will be no callbacks, why would she start using something else? It's high risk and not much benefit. Professionals keep using wire nuts because they have a proven track record of customer satisfaction and safety. Amateurs (homeowners) keep using wire nuts because they don't know of the existence of anything else because they are not stocked in shops and if they are, they are in the "obscure funky stuff" display.
