In the world of electrical wiring, copper stands out as the preferred material for most residential and commercial applications. At Chesapeake Electric, we understand the importance of using quality materials to ensure the safety and efficiency of your electrical systems. Here’s why copper is the go-to choice for electrical wiring in Maryland and beyond.

High Electrical Conductivity

Copper’s outstanding ability to conduct electricity is one of the primary reasons it is used extensively in electrical wiring. It ranks second only to silver in electrical conductivity but is far more abundant and less expensive, making it the practical choice for wiring in homes and buildings.

Durability and Reliability

Copper wiring is durable and has a high tensile strength, which means it can withstand mechanical stresses without breaking. This reliability makes it ideal for installations where longevity and safety are paramount.

Resistance to Corrosion

Copper resists corrosion better than other metals, such as aluminum. This resistance extends the life of the wire and reduces the risk of electrical problems associated with corroded wires, which can include short circuits and electrical fires.


Copper is highly flexible, making it easy to install, especially in tight spaces and around corners. This flexibility also reduces the risk of the wire breaking during installation, further enhancing its safety profile.

Heat Tolerance

Copper can tolerate a significant amount of heat before melting or degrading, which is crucial for preventing overheating and potential fires, particularly in systems that carry a high electrical load.
