Copper has become a go-to material for electrical wiring requirements due to its superior conductivity and durability. Not only is copper more efficient than other materials, but it can also help to reduce energy loss. But when it comes to electrical cable installations, an even more important factor than quality is safety—which is why ampacity rating is so important.
Ampacity ratings measure the amount of current that can safely be carried by electrical cables without compromising the integrity of the wiring or risking a fire. Every electrical cable is rated for maximum ampacity, including those made with copper components. Copper ampacity ratings are determined by the diameter of the cables, the temperature in the surrounding environment, the type of insulation used, and the type of termination used.
When selecting copper cables for a project, it's important to make sure that the cables have an ampacity rating that is higher than the anticipated current drawn by the installation. That way, cables won't get overloaded, and you can avoid electrical fires, safety hazards, and costly repairs. It's also important to pay attention to local building codes, as they may have additional requirements regarding copper ampacity ratings. Following these steps will ensure safer, more reliable wiring and longer life from copper cabling.
