Greetings,
What is the best (cheapest/quickest?) NEC compliant way to join two
wires within a wall that will NOT later be accessible without
disturbing the building finish?
The current method I most often see utilized in past construction is to
strip an area of insulation off of a wire without cutting it, twist
another wire around this wire with many loops and finally apply
electrical tape generously.
Thanks,
William
There's not an NEC compliant way to do it. If you want to do it safely
but not compliant, do what you said but then silver-solder the
connection and wrap with rubber splicing tape. Regular solder isn't
good enough, you'd have to either weld it (and copper is hard to weld)
or use silver solder with a high silver content (like 40%.) It would be
a real pain-in-the-ass to do, and a half-assed job when you were done. HTH
Best regards,
Bob
One ought to follow the NEC, but the way you said
is not the really the safe way. Wires are joined
all over the house and in box and are safe. An
inaccessible box can't be inspected but that
doesn't make it unsafe. In fact, if one wires
inaccessible boxes just like the accessible ones,
one is no more unsafe than the other. But if I
were doing it, which I wouldn't, I would make sure
I used a box that clamps on the romex. The
problem with an inaccessible box is when some
yahoo starts pulling on the wires, the wires are
not stapled as required, and the wires pull
partially apart. You can stop that by using boxes
with clamps.
I think this is all nonsense anyway as you should
never need to use an inaccessible box. Just use
an accessible box that is in full view or hidden
behind a door, a hinged cover, a picture, etc.
