AWG NEC APP allows you to calculate electrical cables based on conductive material type of electrical network current voltage power power factor and voltage drop among other factors. All calculations are based on the NEC 2020 (National Electric Code) of the United States of America.
Conductor size and protection The National Electrical Code requirements for conductor size and overcurrent protection have always been confusing and complex. Factors to consider include 1. Special application 2. Continuous loads 3. Terminal temperature ratings 4. Conductor insulation 5. Conductor amperage 6. Conductor packing 7. Ambient temperature.
AWG NEC APP has more than 15 special circuits shown in the NEC among which are motors air conditioning equipment fire pumps photovoltaic circuits welders feeders converters feeders and branch circuits etc.
AWG NEC APP is the only one in its category that explains step by step the calculation of conductors makes references to NEC articles and gives the result as if you had the NEC handbook open in your hands.
Also the results for the overcurrent device are given. Among the overcurrent devices are fuses and inverse time breakers among others. In some cases such as motors the overload protection device or motor guard is suggested.
To make a calculation of conductors several confusing steps must be followed such as the adjustment for current-carrying conductors the adjustment for the ambient temperature the selection of the conductor according to the capacity of the terminal (60 75 or 90 degrees Celsius) the adjustment for conductors on the roof exposed to the sun (with the exception of XHHN) and many other factors that are taken into account and that the approval of electrical installations in the USA depends on it.
That is why we believe that AWG NEC APP is an indispensable tool for electrical students apprentices and especially electricians who are working in the United States of America.
