Wire Sizing, Splicing And Power Supply - Xylem Goulds M05421 Manual De Instalación, Operación Y Mantenimiento

• Poppet style check valves which
are threaded in from the top of
the discharge head can be easily
removed using a ½" nut driver or
deep socket. The hex hub is visible
and accessible from the top.
• Internal Flomatic™ design plastic
poppet style valves must be
removed from inside which
requires pump disassembly.
• Built-in plastic poppet style valves
with a stem through the top may
be removed from discharge head
by pulling on the stem with pliers.

Hazardous voltage
can shock, burn or
cause death.
Always follow the National Electric
Code (N.E.C.), Canadian Electrical
Code, and any state, provincial, or
local codes.
We suggest using only copper wire.
Size wire from the charts found in
the Technical Data section of this
manual, MAID manual, or an
N.E.C. (National Electric Code)
code book. If discrepancies exist the
N.E.C. book takes precedence over a
manufacturer's recommendations.
3.1 Splicing Wire to
Motor Leads
When the drop cable must be spliced
or connected to the motor lead, it is
necessary that the splice be water-
tight. The splice can be done with
heat shrink kits or waterproof tape.
A. Heat Shrink Splice Instructions
To use a typical heat shrink kit: strip
½" from the motor wires and drop
cable wires; it is best to stagger the
splices. Place the heat shrink tubes
on the wires. Place the crimps on the
wires and crimp the ends. Slide the
heat shrink tubes over the crimps and
heat from the center outward. The
sealant and adhesive will ooze out
the ends when the tube shrinks. The
tube, crimps, sealant, and adhesive
create a very strong, watertight seal.
B. Taped Splice Instructions
A) Strip individual conductor of
insulation only as far as
necessary to provide room for a
stake type connector. Tubular
connectors of the staked type are
preferred. If connector O.D. is
not as large as cable insulation,
build-up with rubber electrical
tape.
B) Tape individual joints with
rubber electrical tape, using two
layers; the first extending two
inches beyond each end of the
conductor insulation end, the
second layer two inches beyond
the ends of the first layer. Wrap
tightly, eliminating air spaces as
much as possible.
C) Tape over the rubber electrical
tape with #33 Scotch electrical
tape, or equivalent, using two
layers as in step "B" and making
each layer overlap the end of the
preceding layer by at least two
inches.
In the case of a cable with three
conductors encased in a single outer
sheath, tape individual conductors as
described, staggering joints.
Total thickness of tape should be no
less than the thickness of the conduc-
tor insulation.
