CHP says its four modules of electrical engineering programs use
decision matrices to automatically apply requirements,
limitations, comparisons, and restrictions as defined by
manufacturers and the National Electrical Code (NEC). With
CircuitSoft, you enter data once, and forward it to the correct
module. CSMain serves as the main menu program for the four
integrated modules: Busses, Distrib, Wirsiz and Ctrl^Z.
 
Busses handles the basis tasks for an electrical design
project, including load identification, determining the NEC
load types (for forwarding to Distrib for load calculations),
and determining the amount of each load in kilowatts or
kilovolt-ampere. It identifies each piece of equipment and its
relationship with other equipment and can perform a balancing
summary for certain classes of panelboards. Distrib, the load
calculation program, calculates the load on each bus, the
branch circuit loads, and the downstream loads that are served
by that bus. Wirsiz calculates transformers, overcurrent
devices, phase and neutral conductors, busway sizes, conduit,
equipment ground wires, and system ground wires. The Ctrl^Z
program calculates voltage drop, short circuit, and fault
let-through of overcurrent protection devices.
 
CircuitSoft runs on the IBM PC AT with 640K bytes of RAM and a
hard-disk drive.
 
Price: $700-$1200 per each unit.
