insulation are a common cause of premature failure.
Splices are not normally allowed except under
certain circumstances. If splices are allowed,
select the "Anode lead to main feeder connections"
option.
**************************************************************************
f.
Splices not allowed: Splices, or repairs to damaged anode lead
wire insulation are not allowed. Install anode lead wires back to
the anode junction box as indicated in the drawings. [Anode lead
to main feeder connections: Make connectors as follows:
**************************************************************************
NOTE: Choose one of the following options.
**************************************************************************
[(1) Remove insulation to expose approximately 50 mm 2 inches of
each conductor.
(2) Make connection between conductors using solderless crimp
connector or exothermic weld.
(3) Cover connection with uncured butyl rubber type to provide
filler wrap.
(4) Apply four layers of half-lapped neoprene tape, extend the
tape over the cable insulation.
(5) Apply two layers of half-lapped pressure sensitive
polyethylene or polyvinyl chloride tape.]

(3)
Cover connection with pre-manufactured splice kit.]]
g. Anode junction box. Mark each of the wires terminating in the
junction box. Install anode junction box as shown in the drawings
[prior to pouring the concrete slab].
h.
Installing lead wires. Connect anode lead wires to the
appropriate terminals in the anode junction box.

Deep Well Anode Ground beds
a.
Drilling of anode well. Drilling of the anode well shall be
accomplished by a qualified well driller. Submit documentation of
experience to the Contracting Officer. Drill a hole [254] [305]
[_____] mm [10] [12] [_____] inches in diameter to the depth
indicated using rotary bit equipment designed specifically for
this purpose. Select the type and consistency of drilling fluids
to be consistent with soil characteristics. The use of temporary
well casings may be necessary. Remove all temporary casings upon
completion of the installation.
b.
Excavation for wire trench.
Excavate anode header cable [_____]
