1. Southwire's voltage drop calculator will help you determine the proper wire size for an electrical circuit based on the voltage drop and current carrying capacity of an electrical circuit.
2. Determines wire size to meet specific voltage drop limits or calculates voltage drop for a specific conductor run.
3. When sizing conductors, calculations limits wire size to voltage drop and NEC ampacity.
4. Southwire's Voltage Drop Calculator is designed for applications using AWG and KCMIL sizes only.
1. Also, it would be nice to have a separate table showing max amps on a specific awg wire, so I know I can't use 12 awg at all, if I need 40 amps; It just doesn't work.I don't know why the Southwire app calculates a different result than the Southwire website.
2. Fix and I will change my review, for voltage drop, ignoring wire size warnings, app works great.Some of the ampacity tables are incorrect.
3. Multiple options, first you have to learn how to calculate several wires of different sizes in one conduit, but after you do it is intuitive and just a great programWorks well for the awg listed, but it doesn't go small enough.
4. And will not calculate wire sizes smaller than 14 AWG; an option to just type in the Cmil area would be nice.Good tool.
5. over and back.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.
6. Ie... size 3 in the app is rated for 85A(60c), but I'm running size 3 THHN(90c) which is good for 115A.Very useful tool, especially when vetting out possible installs with customer during conversations.
7. Would be great otherwise.Spot on, except I wish the app gave an option to select insulation classes of conductors.
8. Your not being conservative your intentionally misleading to sell larger wire.
9. Love it! - John (GF) EC ElectricSome of the information takes up more than 1 line, instead of making the space bigger the app appears to cut of some information.
10. Which one is right? Try, 60amp,copper, 3-phz, 60Hz,208v, conduit, 150ft run, min conductor and 3% allowable v-drop.
11. Just know your ampacity ratings of conductors, and base your selection off of the voltage drop.
