That's clearly nonsense -- 240 is far more dangerous than 120, both in its potential (pardon the pun) to electrocute, and to arc. The claim of reduced heating in the conductors is likewise nonsense: in a properly sized circuit, with proper overcurrent protection, heating in the conductors is insignificant regardless of voltage (i.e. if the conductors are getting hot, it's because they're too small for the load imposed).
From my time in Asia I know that most countries in the region are
220-240v with the exception of Taiwan. When I asked about it I was told that 220-240 systems are cheaper to run.
Everything, I wouldn't even trust them on low voltage door bell wiring let alone anything carrying mains voltage and current.
They are pure unadulterated crap.
So there is an equivalent to a wirenut is there? I'm having great difficulty thinking of anything else that could "perform" a similar "function" and be so badly engineered for the task in hand.
Google images "wire nut" and "wirenut" brings up quite a good selection.
Fortunately I reside in the true land of the free where higher standards are used in electrical installations. Basically just about everywhere other than the USA.
The National Electrical Code 110.14 state:
"Splices shall be made with an approved splice cap or ?wire nut?."
What do you use in place of wire nuts?
You want an argument, change the subject.

Fortunately I'm not bound by "The National Electrical Code"
So I use either proper screw terminals usually fitted with a rising leaf spring or preferably gas tight crimps, crimped with an approved, calibrated crimp tool and then protected with adhesive lined, low smoke and fume, zero halogen heat shrink This latter method in particular quickly gives a guaranteed low impedance connection that will last decades. i.e. the professional way to do it, not the bodgit and scarper method espoused by "The National Electrical Code"
Wasn't it Michael Faraday that called the USA "The land of the free and home of the smoldering wirenut?"
I agree. They are not used because they are the best. They are used because they are the least they can get away with.
You want a properly engineered electrical installation, emigrate :)
So what do you use?
Please post a link to one of those images in which there was a fire caused by wirenuts. The only images I find that are at all relevant show burnt wirenuts due to improper use with aluminum wire in violation of code, and in none of them was there any indication of a structure fire. Now admittedly I did not take the time to examine more than the first ten pages or so of images.
The question was not where you reside, the question was what you use in lieu of wire nuts. So what do you use? Or don't you know?
I'm curious about what you consider an acceptable alternative.
So you use screws to splice three wires together? That's downright scary.
As for your gas tight crimps, those things are so dependent on your calibrated tool that they ought to be outlawed. Talk about a fire hazard.
Oh, and your beer sucks.
And you have yet to explain to us what you use wherever you live to serve the function served in the US by wire nuts.
Depends on the application and type of conductors involved.
Lew
Lew? I didn't realize you were the OP. Anyway, here's a specific example, tell me what you would use in the place of wire nuts:
Ceiling junction box with light fixture attached, power coming directly to the that box, with a switch loop going to a wall mounted switch. Using regular NM (Romex) cabling.
How would you connect the line neutral to the light fixture neutral,the line hot to the switch loop, and the return from the switch loop to the light fixture hot conductor?
Tim Douglass wrote in news: snipped-for-privacy@4ax.com:
is controlled by the amount of resistance on the circuit, with the most basic factor controlling resistance being the size of the wire. If we shrink the wire two things happen; first, less power gets through, and second, the wire heats up at that point.
You wrote this? This is really a 'dumbed down' start. I stopped reading after the above. I'm sure you are experienced with electricity and understand home wiring very well, but your explanation of it needs work. No offense meant. Hank
Here I look at a subject line to which the answer is, yes it can. But then again so can "to code wiring".

What you are describing is the classic application for which the wirenut was designed to solve.
Namely, the joining of a solid conductor (Romex) and a stranded pigtail (the lighting fixture).
It is not a particularly good long term connection; however, there are some conditions in this application that minimize future problems.
1) There is very little chance of vibration impacting the wirenut termination.2) The load is probably 600 watts or less so long term heat build up as a result of a high resistance connection is minimized.
About the only possible alternate to a wirenut that is economically viable would be a butt splice connector which would be totally dependent on being able to make a proper mechanical crimp on a solid conductor, something I'm not qualified to comment on, but would refer to the splice manufacturer.
Lew
OK... Are you saying that you WOULD use a wirenut in this case? :)
