Disclaimer: These recommendations are based on standard industry guidelines and are intended for informational purposes only. Always seek guidance from a licensed electrician or qualified professional to ensure your installation complies with local regulations and meets all necessary safety requirements.
As a general guideline, it is recommended not to exceed 80% of a wire’s current-carrying capacity. This calculator already incorporates that safety margin in its design.
If you are operating at a different system voltage (such as 12V vs 24V), this will affect the current flow; however, the wire size chart provided already accounts for typical low-voltage lighting applications.
If your project involves unusual conditions—such as longer wire runs, higher wattage loads, or multiple circuits on the same wire—it is advisable to consult a licensed electrician.
