I am finding myself in need of a Electrical calculator more often then before.
Like the "Ugly's Book" I need something that will allow me to figure out amperage for sizing conductor size, breaker size, etc. I don't need to figure phase angles, or lead lag of volt/current but the more practical applications of say calculating amperage of a three phase motor for 480, 4160, 13.8Kv would be nice.
IF a calculator is not available a reference book with tables and formulas would work then it would be a matter of switching apps to go from reference to the built in calculator.
Any ideas out there would be greatly appreciated!
