Are concrete-encased electrodes only permissible in new construction?

Concrete-encased electrodes are primarily designed to provide effective grounding for lightning protection systems and electrical installations. They consist of conductive materials embedded within concrete, which enhances their connection to the earth.

The correct answer maintains that these electrodes are only permissible in new construction because their implementation requires specific design considerations and structural integration that can only be effectively accomplished during the initial construction phase. Retrofitting existing structures with concrete-encased electrodes can be complex and impractical, as it involves significant alterations to the current building structure, which may not comply with safety regulations or building codes.

In contrast, while some grounding methods can be employed in renovations or existing buildings, concrete-encased electrodes must be integrated appropriately during the build process to ensure optimal conduction and durability. Therefore, they are inherently limited to new construction scenarios for proper installation and compliance with industry standards.
