I have never trusted stranded wire connetions. I've seen too many go

takes a few extra minutes, but in my view, it's always worth it.


Note, however, that the National Electrical Code requires that a mechanical
fastener (such as a wire nut) must be used _in_addition_ to the solder.
A connection made by solder alone is a Code violation.


Can you quote me chapter and verse on that assertion. I am unaware of
any such provision in the code except that "Connections depending solely
on solder shall not be used" in attaching Equipment Grounding Conductors
to boxes. A splice that is made up mechanically and then soldered is
perfectly acceptable as is shown by the reference in 250.148 to 110.14.


That, of course, is _exactly_ what I said: a mechanical fastener must be used
in addition to the solder. And you cited the relevant portion of the Code
yourself:


110.14 Electrical Connections.

[...]

(B) Splices. [...] Soldered splices shall first be spliced or
joined so as to be mechanically and electrically secure without solder
and then be soldered.


Actually, this means that the wires should be twisted
together to make a solid connection prior to being soldered
as opposed to just having the wires next to each other and
soldered. The twisting together makes the joint mechanically
and electrically secure.
