the breaker size and circuit description. In this example
the connected VA is entered in the VA column.
the panel is 3-phase WYE an H column appears. If the load is
electronic equipment such as a computer or electronic ballast,
you need to identify the load with an H.
NEC requires the neutral conductor be treated as a current
carrying conductor when 50% of the load is subject to harmonic
currents. When this harmonic load condition exists, the program
will de-rate the conductor amps to 80% per NEC requirements.
is a continuous load so enter a C in the I column. The program
will add 25% for continuous loads per NEC.
