An electrical conductor is, in simplest terms, the wire that electric current flows through. It is a component that carries the current from a source (electric panel) to the load (device requiring electricity). The current itself is able to flow freely when an electric charge is applied.
Conductors are aluminum or copper wires that help to carry volts and current to and from electrical device that need electricity to work. These transport medias allow electrons to travel in the form of a current. The conductors in a modern home are copper wires. Copper is the most safe and reliable. Aluminum is used by utility companies for moving power from the plant, through substations and transformers and to your meter.
Aluminum was used for in home distribution from the mid 60s through the mid 70s, however was outlawed in most areas by 1976 for safety issues. If you have aluminum distribution, consult an electrician for repairs. It is incredibly rare that the home will need to be rewired, however, all outlets and switches will need repair.
Ultimately, a professional electrician can evaluate a home’s current system and determine if it is up to code, running efficiently and safely and/or needs an update. An outdated system can lead to increased risk of fire and electrical shorts in a home.
