An uninsulated section of a single conductor should not be looped
around the terminal and serve as two separate connections. The
wire must be severed, thereby providing supervision of the
connection in the event that the wire become dislodged from under
the terminal. Failure to sever the wire may render the device
inoperable risking severe property damage and loss of life.
Do not strip wire beyond 3/8" of length or expose an uninsulated
conductor beyond the edge of the terminal block. When using
stranded wire, capture all strands under the clamping plate.
