What is a concrete-encased electrode?

A concrete-encased electrode is defined as a metal conductor that is embedded in concrete and functions as a grounding electrode. This grounding method is crucial for ensuring safety in electrical installations by providing a low-resistance path to the ground. When the metal conductor is buried within the concrete, it becomes an effective means of grounding, helping to dissipate electrical faults and preventing shock hazards.

This technique is often utilized in building foundations or footings, where the concrete provides additional protection against physical damage to the conductor and enhances its effectiveness in grounding applications. Proper installation and adherence to the National Electrical Code (NEC) guidelines ensure that the concrete-encased electrode performs optimally in providing electrical safety.
