12 — ElectriCalc LT
Voltage Drop Solutions
The
ElectriCalc LT
will calculate maxi-
mum 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
factors such as inductive reactance,
skin effect, raceway material, etc., are
not considered
[VD%] — 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 avail-
able, “nonE” will display since the volt-
age 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 %
