Can someone tell me the best way to wire-nut 5 #12 wires in a 4x4"
box. I know that a red nut will accept 5 #12 solid wires, but is
there a better way ? I have seen posts that talk about con-blocks and
others that talk about compression nuts. I can't find either at
HomeDepot or any other big box.
Any help is appreciated.
I know Radio Shack (and others) sell these for low voltage connections
but are they NEC approved for house wiring?
I Googled them and all the sites that carry larger sizes seem to be in
the UK or NZ.
I was first introduced to them while serving in the USCG in Germany
back in the late seventies, but again, only for low voltage apps.
Are they NEC approved to be used in the application the OP described?
You could also use a small copper split-bolt and (assuming it's not a
grounding wire) wrap it with tape.
If I was using a wire-nut, I'd go one size bigger than red (don't
remember what color that is, blue?)
Sorry for hijacking...
Had to laugh when viewing that page. Main item: wire nuts.

Gotta love software (or more likely, keyword coding) that comes up
with that combination. And I've seen ridiculous suggestions on plenty
of other sites and pages.
Amazon usually has relevant suggestions, but I've seen some crazy ones
One of the most memorable goofy suggestions was at Cabellas or some
other big sportsman store. I was searching for combination sunscreen
and bug repellant, which it found. The related item it suggested was

Just hijacking along...
re: The related item it suggested was a 5 pack of pitons (the things
mountain climbers pound into rocks to secure lines).
Makes sense to me. The last thing I want to have happen when hanging
off a cliff a couple of hundred feet above some jagged rocks is for a
mosquito to start gnawing on my neck.
Bug repellent and mountain climbing gear go hand in hand. <g>
Surprised to see someone make that suggestion.
Yes, it would definitely be a superior connection, both electrically and
mechanically. But aside from the extra work involved, it has the problem
of not being easily un-doable in case some future electrician needs to
fix or add something.
Kind of like the old Western Union splices ...

It would appear that cutting back the wires after soldering would
violate NEC 110.14(B): "Soldered splices shall first be spliced or
joined so as to be mechanically and electrically secure without solder
and then be soldered."
Also, NEC 250.148(E) prohibits relying on solder for the grounding
conductor (EGC): "Connections depending solely on solder shall not be
Sounds fine, as long as the conductors are still mechanically secure
I have a couple issues with this interpretation. First, it makes
250.148(E) purely redundant to 110.14(B). Second, under your
interpretation, why add the solder at all? Just twist to be
mechanically and electrically secure. So instead, I take "depending
solely on solder" to mean "consists only of the conductors plus the
Here's a clearer citation on the prohibition of soldering for the
grounding conductor that is new to the 2008 NEC: 250.8(A) says
"Permitted Methods. Grounding conductors and bonding jumpers shall be
connected by one of the following means:" and then does not include
soldering in the list of acceptable methods.
