Simple quick easy. This is faster then scrolling through ABYC tables, and your phone is always with you, unlike those pieces of paper. I'd like to see more info like wire ampacity and more variables such number of cables in a bundle, etc. like the blue sea circuit wizard does.

Great app!. This app is great for a non-electrician to use!

Only does DC current.. Lame

Easy to use and accurate. 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.

Easy to use and intuitive. Easy to use and intuitive. Great when working on the boat's wiring.

Great ap for the boat. Rewiring my boat. 12v. And works like a charm

Very helpful, limited to 50VDC. 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!

Limited. Need AC and higher voltages. Easy to use but needs more configurations

Great easy to use wire gauge calculator. I use this app in my marine electrical business and find it a valuable tool. No having to lookup or calculate wire thickness while running wire.

Only does up to 50V DC. No high voltage and no AC.

Works like a charm. Works very well and the interface is very easy to use

Simple. Easy. Great simple app for quick calcs.

Great app for simple DC work. Great for simple DC wire engineering

Super helpful and easy. As a marine systems engineer this app is extremely helpful and saves time when doing wire calculations. I would strongly suggest this app for anyone that needs to calculate wire sizes, it's worth .99!!

Solar electrician. This is a waste of my money

Great app. This is a great app for low voltage wiring. I love that they recently added fractional amps as well for those of us using very low wattage led lights. Thanks!

Really dude, you gave a poor rating to a good app because you didn’t read the screen or description. Both the screens and the description reviews indicate the App is for DC (before the More). It’s not fair to give a poor review because you didn’t take the time to read the description. This was one of the first marine DC wire sizing apps in the AppStore and he’s continued to improve on the app over the years. It’s a good app by a caring developer and an experienced boater.

Very Useful. Easy intuitive app that has been very helpful in my work

Works well, some limitations. 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.

Way cool and useful for projects!. Working on solar for my trailer. I’m confident I’ve got the right wire sizes.

Owner. I like this app, simple. Just need to allow higher dc voltages for mppt charger controllers.

Handy for DC only. Simple, easy. I would rate the app 5 stars if it did AC calculations.

Terrific app! Simple, as it ought to be. I use it daily in my boat electrical work. I would like an AC calculation for higher voltages, in future versions of the app.

Owner. Great handy app. Quick and simple.

Wire Sizer. Awesome

Great app.. Very useful.

FAST calculator + handy material list.. This is an absolute must have! As a home DIYer I wish I had this years ago instead of referring to a chart as a guide. In the process of Installing a vehicle 12v and solar system and this has become extremely handy and sped up the building process significantly. The ‘+’ for material list is the cherry on top. Highly recommend A+++

Wire sizer app. This is a fantastic app that is really accurate. The app has made my life so much easier when re-wiring my boat. 👍

Dan Caracas. Same as my colleague : AC = also necessary

Handy. I use it often for remote well sites that use DC. It's handy and easy to use. Lengths aren't long enough sometimes.

Excellente application. J'enseigne l'électricité à des plaisanciers depuis plus de 20 ans. Wire Sizer est une application de calcul que je recommande chaudement à mes élèves, de par son aspect pratique, utilitaire et son efficacité. De plus elle répond aux normes ABYC ce qui en fait un produit hautement recommandable.
