Installing NEC UpdatesYour ElectriCalc Pro is now updateablefor future National Electrical Code editions that are updated every three(3) years (next Code update is 2005).To upgrade your unit, follow the instruc-

tions below:1) Purchase the NEC Update from CI(see pricing & details from CIs Website: www.calculated.com or call 1-800-854-8075). This Update is in theform of a chip that contains the newCode.

2) Once you receive the NEC Updatechip, you need to install it in yourElectriCalc Pro:a)Turn calculator off.b)As a precaution, remove the bat-

tery (located back of calculator, topof unit) by sliding battery door out

with your thumbnail. Set aside.c) Using a screwdriver, pop out thesquare tab located in the middlesection on the back of your calcu-lator.

d)Replace it with the new Update tabby inserting it into the slot.

e) Replace the battery door.f) Turn calculator on. Your calculator

is now updated and ready to use.

34 ElectriCalc Pro

Motor HorsepowerThe ElectriCalc Pro can calculate thefull load current (amps) of a motor,based on phase, voltage and motor(synchronous or induction). It usesNEC Tables 430-148 and 430-150 to

determine the motor full load current. (Ifyou enter a value for HP or voltage thatdoes not correspond to these tables,the unit will display Error 8).

The ElectriCalc Pro can also calculatean equivalent horsepower for either aninduction or a synchronous motorbased on a voltage, phase and full loadcurrent. When calculating motor HPfrom an entered amperage, a result notdirectly matching a value in NEC Table430-148 or 430-150 will cause the cal-culator to choose the next higher table

value for motor horsepower.

Voltage DropThe reduction in voltage between thepower source and the load can be de-termined by entering the phase, volts,amps, wire material, voltage drop wiresize and length of run. The calculator

determines resistance and then thevoltage reduction. Voltage drop can bedisplayed as volts dropped, or as apercent reduction of potential load.

This calculator also finds voltage dropwire size once you have entered orcalculated the phase, volts, amps,length, wire type, and allowable VDpercentage. It will solve for the distance([Length]) once you have entered orcalculated the phase, volts, amps, wiretype, voltage drop wire size, and allow-able VD percentage. The ElectriCalc

Pro uses resistance values found inNEC Table 8 to determine voltage drop.

NOTE: Voltage drop solutions may vary slightly from actual AC circuit meas- urements as the calculator does notincorporate factors such as inductive reactance, skin effect, raceway material, etc. In most situations, the DC Voltage Drop calculation is sufficient to meet safety standards.

IMPORTANT NOTE ONVOLTAGE DROP CALCULATIONS

The ElectriCalc Pro calculates voltagedrop and wire size using DC resistanceas defined by the 2002 NEC. To findthe voltage drop for a specific wire size,you must first enter amps and the one-

way wire length (and other requiredvariables), entering the specific wiresize last . Otherwise, for your safety thecalculator will recalculate the wire sizesbased on the 99 NEC Ampacity Tablesand maximum allowable voltage drop.
