Voltage Drop Solutions
The ElectriCalc Pro will calculate
maximum lengths, minimum wire sizes
or actual voltage drops given the other
two values. Voltage drop solutions are
based on the DC resistance values
found in NEC Chapter 9, Table 8.
NOTE: Voltage drop solutions may vary
slightly from actual AC circuit values as
the calculator does not incorporate
factors such as inductive reactance,
skin effect, raceway material, etc.
v
— Percent Voltage Drop
Used to enter or calculate voltage drop.
The default voltage drop is 3%. If wire size
or wire length values are not available,
“nonE” will display since the voltage drop
cannot be found.
♦ First Press
Enters a maximum allowable voltage
drop percentage (Displays: V DROP
%) or calculates actual Voltage drop
(Displays: V DROP).
♦ Second Press
Calculates actual percent Voltage drop.
Displays: V DROP %
l
— Length
Enters or calculates the length of a run
for Voltage drop calculation.
Displays: FEET or MET
NOTE: Units of length can be set to
Feet or Meters by use of the Prefer-
ence function
