only by workers experienced in the work and approved by the Engineer. Letter of
certification demonstrating experience making MV-90/MV-105 splices over the past five
years shall be submitted prior to commencement of the work. Material for this splice shall
be at Contractor's expense.

ground wire to equipment enclosure, ground system and ground rod. Ground all splices and
terminations, and cable sheaths where outer jacket is removed.
3.6
Cable Slack: Route all cables along the longest path (#180E) in a manhole or pit prior to
exiting. Provide maximum cable length by dressing the loops against the walls.
3.7
Bends: Provide maximum practical radius on all bends. Cable lengths bent to less than the
manufacturer's minimum authorized radius, at any point and for any duration of time, shall
be replaced as below.
3.8
