Features & Capabilities

Circuit Wizard is designed to help electricians and enthusiasts determine wire sizing for a given installation based upon specific parameters using ABYC and Blue Sea Systems specifications.

Once a wire size is known you can then use that information to search for products offered by Blue Sea Systems in order to protect your circuit.

Based upon the popular web application located at http://cw.bluesea.com/, this version is designed to be run completely offline which should be useful in situations where an internet connected computer is not available.

User Reviews

Circuit Wizard is praised as easy to use and fast for sizing DC wiring, especially for boats. Reviewers note it saves time by calculating wire sizes from voltage drop or ampacity and is a must-have tool for installers. However, users frequently report stability issues (crashes/freezes when selecting functions) and a lack of 48V support and limited voltage options (no 110V). Some request more customization (higher insulation temps, custom values). Overall it’s a promising, time-saving utility that needs bug fixes and broader voltage coverage.

Pros

Easy to use and intuitive interface
Very quick and easy to determine the right wire size based on voltage drop or ampacity
Useful tool for boat installers/electricians; a must-have that saves time
Helps avoid digging through standard tables and speeds up sizing

Cons

Missing 48V calculator / lack of 48V support
Crashes or freezes when selecting functions; stability issues
Limited voltage options (no 110V; only 12/24/32)

Crashes when selecting a function

by t3*****, 2025-03-23

Downloaded on my iPhone 14Pro today. I’m on the latest iOS 17.3.1. The App opens but as soon as I select one of the functions such as calculate wire size the app momentarily freezes then closes. Only the history function actually works but that’s useless since it won’t do anything. There’s no setup or menu available for configuring the app so I see no way to fix this issue. Must be a bug in the app. Till it’s fixed, it’s useless.
