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.

I was trying to draw a difference between what you were saying and what
the code actually requires. I now understand that you believe that the
code forbids traditional soldered splices. I don't believe it does and
when I have had to do repairs and extensions of knob and tube wiring I
have made up mechanical splices by twisting or wrapping the conductors
around each other in the traditional manor creating at least three full
turns, then soldered, followed by taping. So far I have passed
inspection. I would like you to tell me how you would solder a splice
that is already covered with a solderless connector. The language of
section 110.14 requires that the conductors be spliced or joined first
and then soldered.

I think I'll just continue to use the traditional method, were it is
appropriate, and if an inspector ever refuses it I'll see what the state
board of appeals has to say. You see if your position were correct it
would be absolutely pointless to use solder. I have to believe that the
code making panel did not put in language on soldered splices just to
render the practice useless. If that was the intention they would have
simply forbid the use of soldering as a splicing technique.
