NThe length of exposed wires is critical. The ideal length is 3/16” (5 mm).

•If the stripped section of wire is longer than 3/16”, the exposed wires may touch, causing a short circuit between them.

•If the stripped section of wire is shorter than 3/16”, wires can be easily pulled out even if tightly fastened by the captive screws.
