Voltage Drop Calculator

Best app for computation

Just what the doctor ordered

Simple way to get results, interface is a little primitive but works. I would be using this for Solar DC calcs, and was wondering if the Distance parameter is for one way of cable, or the loop of wire from panel to battery, then back to panel? Thanks

Great app. No permissions needed, no advertising, and quick to use with minimal keystrokes. Standard & metric units. Really nice. A few suggestions: Would be nice to have the option to disable the 'vibrate on key press', and re-wording the "distance" to "one-way distance" or something similar. Also, adding a "voltage at end of cable" result would be great (input voltage - voltage drop), so I don't have to do the subtraction in my head. Nice work!

Tried it and for 480 volt 100 meter run it told me I needed #1 for 200 amps with a maximum allowable volt drop of 3%. Obviously that was wrong and I found a better app

Useful and simple!

This is the best app for electrical engineers and Electricians

Muy bueno

Does what it says, and has metric units support. Fantastic.

Very useful

Good it is nice

Love it. Handy, and the metric unit is so useful for me. Thank you for this!

Quite neat how it is all on one screen. Imperial and metric. Big, logical pushbuttons for simplicity. This will suit many people but not everyone - I personally like it. BUT something I loathe... it bangs a zero on many numbers you enter. You type (say) 150 metres for a cable run, and it returns an absurd result, like telling you to use 25 mm2 cable. Clearly wrong - and you glance over the data, and its for a 1.5km cable run. Enter 240 (volts), and suddenly its 2400V. Grrrr ... instead of programming tricks, just accept the user data huh! This is *really* annoying, but otherwise it is a pretty reasonable, compact app. I kept it.
