How can you see the nut, it must be on the other side of the wire.

Pretty sure he means the blue one.

I don't get it, if you are going to do something that stupid, surely there was a lug somewhere in the box that they could have jammed that wire into. It would have been just as bad but I would have rather seen a double lug then that.

As a teachable example for those who don't know, I'm sure you all realize that that if the small wire shorted out somewhere, there's no circuit breaker to trip. And it could easily be asked to pass hundreds of amperes of current, causing it to vaporize and making something called an arc-flash blast. That's WAY dangerous since the resultant fireball is hotter than the surface of the sun moving at faster than the speed of sound. It's an electrician's worst nightmare. https://www.youtube.com/watch?v=dPJtknGmsys

The first problem is the wire is wrapped the wrong way around the screw.

Only on PSW!   Ha.

The devil is in the details.

The wire nut is a size too small?

Or the strip is too long.  Love the backwrap on the screw too.

Ummmm..... I think we're way beyond discussing best practices for wire nuts. But since we're there, I like to do mine twisted and taped.

[Stephen Kirby]

I guess they don't make these in 000 size.   



On a slightly more serious note;  Mike, what is your opinion on the "waterproof" wire nuts.  I've used them on my sailboat but I see them in the hardware stores as if they were an improvement for home wiring.

I've long thought that whoever wrote the NEC had stock or relatives in the wire nut industry.  As a manufacturing engineer with background in weapons spec electronics, that's probably the last way I would choose to hook wires together.  Especially in things like putting two duplex outlets in a box as opposed to using both terminals and the tie bar.

Others on this forum are likely more involved with wire nuts, but I've seen these waterproof nuts in a few stores and always passed over them. For serious waterproofing we always used self-sealing electrical tape which makes its own gooey sealant. Of course it's nearly impossible to get the mess apart a year later, but I'm pretty sure it's not going to leak. Of course, anything like waterproof wire nuts or self-sealing tape is not a substitute for a weatherproof enclosure, but it's certainly a good backup if the enclosure seal fails for any reason.
