## Description

Get the right wire size in seconds. Spin the wheels, read the gauge. No keyboard or internet needed. Ad-free. ABYC E-11 compliant up to 60 VDC. <br><br>WireSizer is the trusted DC wire gauge and voltage drop calculator for choosing the correct wire size every time.<br><br>WireSizer is ideal for:<br>• Boats and marine electrical systems<br>• RVs, trucks, and cars<br>• Radios and electronics<br>• Solar power and battery-based DC systems<br>• Any low-voltage DC system up to 60 VDC<br><br>Suitable for both professionals and DIY users.<br><br>WireSizer automatically calculates the minimum wire size required for your circuit (assuming copper wire), taking Voltage Drop into account for installation and temperature conditions. Results are checked against current-carrying capacity (ampacity) limits to prevent using unsafe undersized wire.<br><br>Supported values:<br> • Voltage up to 60 VDC<br> • Current up to 500 amps<br> • Total circuit length up to 600 feet or 200 meters<br> • Voltage Drop from 1 to 20 percent<br> • AWG wire 18 to 4/0 gauge, plus 250 &amp; 300 kcmil<br> • SAE wire 18 to 4/0 gauge,<br> • Metric wire 75 mm² to 150 mm²<br><br>WireSizer allows you to fine-tune calculations based on real-world installation conditions:<br> • Engine compartment or other high-temperature environments<br> • Sheathed, bundled, or conduit-run wire<br> • Wire insulation ratings from 60°C to 200°C<br><br>WireSizer calculates DC wire sizes in accordance with ABYC E-11 (July 2025). For most circuits, results also correspond with ISO 13297:2020.<br><br>Results are a design aid; final wire selection and installation compliance remain the installer&#39;s responsibility. <br><br>Number and decimal formatting will follow your device&#39;s regional and language settings.<br><br>WireSizer works without an internet connection and contains no ads.<br><br>Designed exclusively for DC circuits - not for use with AC circuits.<br><br>Results are a design aid. Final wire selection and installation compliance remain the installer&#39;s responsibility.<br><br>WireSizer will cost you less than the wire scraps you probably throw away at the end of the day.
