What should be done as the length of an electrical run increases?

As the length of an electrical run increases, the wire experiences greater resistance, which can lead to voltage drop. This can result in inadequate voltage reaching the appliances or devices that the wire is supplying. To mitigate the effects of resistance and ensure that the electrical system operates safely and efficiently, it is essential to use a larger wire size.

Increasing the wire size reduces resistance, allowing for better conductivity and minimizing voltage drop over longer distances. A larger diameter wire allows more current to flow with less resistance, thereby maintaining the voltage level across the circuit.

This practice aligns with electrical codes and guidelines, which often specify that wire gauge must be adjusted accordingly based on the length of the run and the amount of current that the circuit will carry. Therefore, increasing the wire size is the appropriate measure when dealing with longer electrical runs to ensure safety and efficiency in the electrical system.
