DC Heating Fundamentals
Unlike AC heaters, DC heaters are limited by the current (Amps) the power source can provide. Ensure your wires and switches are rated for the Calculated Current shown above.
Pro Tip: For 12V systems, keep the wire length short. If the required length is too long for your space, use a thinner gauge wire (higher SWG number) to increase resistance.
