The length of the exposed wires in the stripping process
is critical. The ideal length is 3/16” (5 mm). Any longer
and the exposed wires may touch, causing a short circuit
between them. Any shorter and the wires can be easily
pulled out even if tightly fastened by the captive screws.
C
Do not tin the wires. Tinned wire does not hold its
shape and can become loose over time.
