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.
