WireSizer - DC Voltage Drop

I am a Marine Engineer and I use this app at my desk and in the field to run “how to” calculations to determine the wire size required for a particular voltage, load current and circuit run. The spinner wheels make it very easy to enter the data and the drill down that is available when the results tapped is an excellent bonus. My favorite wire sizing app.

I use this app all the time! Would use it even more if it could support higher voltages. I’d like to see at least 150vdc, and 240vac. Thanks for the useful tool!

Overall it’s a very good tool. I use it to size DC wires runs for solar. I have verified accuracy with manual calculations of voltage drop. It’s limited to 50vdc maximum so works well for up to 48vdc battery banks but can’t use it for solar panels in series as voltage exceed 50v limit.
