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 changing the preference

setting (see “Preference Settings”).
