14 — ElectriCalc Pro
[ParSz] — Parallel Size
Used to find the size of parallel conduc-
tors using amperage and an entered
quantity of wires. Parallel wire size
computations smaller than 1/0 are dis-
played as “none” (display shows
“nonE”) as the NEC does not allow
parallel wire runs smaller than 1/0.
♦
First Press
When preceded by a number, calcu-
lates the applicable wire size for that
quantity of wires in parallel.
Displays: PAR WIRE SIZE.
♦
Second Press
Displays the maximum adjusted am-
pacity of the calculated parallel wire
size. Displays: WIRE A.
NOTE: No adjustments are made for
deration.
[Set] [ParSz] — Derated Wire Size
Used to calculate derated wire sizes
and allowable ampacity based on the
entered quantity of wires, NEC Table
310-16 and NEC Table 310-15(b)(2)(a).
Derated wire sizes are not calculated
when there are less than 4 wires, or
when the unit is in Free Air mode.
