Description |
| Select range ratings from 1 3/4 KW to 27 KW and number of ranges and this program determines the demand load using Table 220.55 and Notes 1, 2, and 3. Loads for up to 1000 ranges can be determined. Nine examples from the NEC, textbooks, and the author are included. | |
| Enter the continuous and noncontinuous load then select the conductor insulation, terminal temperature, ambient temperature, number of current carrying conductors and this program finds the correct wire size and maximum and minimum over current protective devices and the respective size of the equipment grounding conductors. Also includes special condition buttons for nipples, AC/MC cable, equipment rated for continuous loads, and circuit is for receptacles for cord and plug connected equipment. Conductor size is automatically adjusted to the conditions according to the NEC. Results are automatically entered into a voltage drop calculator that calculates voltage drop with an option to increase wire size and proportionately increase the equipment grounding conductor size. Examples and notes on how programs operates are included. | |
