The American Boat and Yacht Council has launched a new wire-sizing smartphone application that calculates minimum conductor size for boats based on the parameters entered, considering voltage, voltage drop and wire run length.

The ABYC, which creates the standards for increasingly complex wiring, released a video geared to manufacturers, technicians and installers explaining how the app can help them translate the power needs of appliances into safe and compliant wire-sizing calculations.

“While it’s up to the individual manufacturers to keep up with consumer demand for high-tech systems onboard boats, it’s up to ABYC to provide a safe framework of design standards that builders, installers and service technicians can rely on,” ABYC education development manager Matt Wienold said in a statement. “This app sets out to streamline the design and service process by offering simple, easy-to-input fields to yield a result which you can rely on to get the job done safely, effectively and efficiently.”

The ABYC wire-sizer app is designed to meet the wire-sizing requirements found in ABYC standard E-11, AC & DC Electrical Systems on Boats.

An international tool, the app incorporates wire-sizing calculations using ABYC U.S. methodology, as well as International Organization for Standardization European methodology. American Wire Gauge results are based on ABYC requirements and the metric (mm2) results are based on ISO requirements.

Wire-sizer app capabilities include:

  • Calculates the minimum wire size, using voltage drop requirements (either 10 percent or 3 percent, depending on your application), conductor maximum ampacity, insulation temperature rating, conductor bundling and more
  • Can be used for DC wiring (12V, 24V and 32V) as well as AC wiring (120V, 240V and 230V)
  • Covers DC and AC shore power wire sizing, derating based on wire bundle sizes
  • Expands upon existing voltage drop tables found within the ABYC standards by covering higher amperage levels typical to equipment such as bow thrusters and anchor windlasses.

The ABYC wire-sizer app is available for download on iTunes and Google Play.
