Would be more helpful if it could look up capacities of medium voltage conductors.

Good tool. Would like min conductor Calc to allow CU or AL wire. SHOULD clarify that run distance is one way vs. over and back.

Must-have for all involved in electrical project for quick, accurate answers with a +/- standard deviation.
★★★★☆Merlin StWahgwaan· Aug 9, 2024
Very useful app! Very easy to explain and show a non-electrically inclined person why they have voltage issues under full load with long wire runs of insufficient gauge. Only suggestion would be, add split phase (dual phase) selections, as most of North America residential and small commercial power is 240v split phase, not just single phase 120v or three-phase as is available in the app now.
★★★★☆Jeff Stowasser· Mar 12, 2020
Spot on, except I wish the app gave an option to select insulation classes of conductors. Instead, it defaults to 60c insulation which is strange being that 75c is a typical spec. Just know your ampacity ratings of conductors, and base your selection off of the voltage drop. I.e... size 3 in the app is rated for 85A(60c), but I'm running size 3 THHN(90c) which is good for 115A.

I like this calculator. Made it quick and easy to find out what size copper direct bury wire I need.

Great App Bad Advice, I know you sell wire, but intentionally misinforming users about Table 310.15(B)(16) in the NEC isn't okay. You're not being conservative your intentionally misleading to sell larger wire. Fix and I will change my review, for voltage drop, ignoring wire size warnings, app works great.

Some of the ampacity tables are incorrect. 4/0 aluminum is listed as 205 amps at 75 degrees Celsius. In fact, it is only good for 180 amps at that temperature.
★★☆☆☆Eric Sillers· May 19, 2021
Okay, I guess. It would be better to see data presented in a table format. No default options for low voltages. And will not calculate wire sizes smaller than 14 AWG; an option to just type in the Cmil area would be nice.

I don't know why the South wire app calculates a different result than the South wire website. Which one is right? Try, 60amp,copper, 3-phz, 60Hz,208v, conduit, 150ft run, min conductor and 3% allowable v-drop. Would be great otherwise.
