From elsewhere in the same series:
"17. The characteristic heating in a band around the connector shows us
where the heat is being generated. In all of those failures shown, from
both lab and homes, the heat is generated by current flowing in the
connector spring. Here, all of the current is passing from wire-to-wire
through sections of the steel spring."

Wire nut must be sufficient to carry the current
AND wires must be twisted so they can carry the current. Only then
does a superb connection exist.
..
The village idiot still hasn’t figured out what *his* source says "In
the design of twist-on wire connectors THE PURPOSE OF THE SPRING IS TO
MAINTAIN TENSION ON THE SPLICED WIRES, NOT TO CONDUCT ELECTRICITY ITSELF."

Nor has he shown requirements from any manufacturer, or UL or the NEC
that wires be twisted.

As usual he just repeats the same drivel.
