How many feet before electric starts to drop?

The effectiveness of electric power transmission can vary based on several factors, including the type of cable, voltage level, and load conditions. Generally, voltage drop becomes significant after about 100 feet (30 meters) for standard residential wiring, particularly if the wire gauge is not adequate for the load. For longer distances, it’s advisable to use thicker wires or higher voltage systems to minimize losses. Always consult local electrical codes and standards for specific guidelines.
