What must an inspector check when evaluating an existing installation?

When evaluating an existing installation, it is essential for an inspector to check compliance with current regulations, as these regulations may have evolved since the time the installation was completed. This aspect ensures that the installation is safe, reliable, and adheres to modern standards that are designed to protect both users and the environment.

Regulations can change due to advancements in technology, shifts in safety standards, or updated practices aimed at improving overall efficiency and safety. An inspector must determine whether the existing installation meets the current codes and standards applicable to the specific type of work carried out. This involves looking at various factors such as electrical safety, building codes, and environmental regulations.

While aspects such as the durability of materials, aesthetic quality, and cost may have relevance in context, they do not primarily determine whether the installation is compliant with contemporary safety standards and legal requirements, which is the core responsibility of an inspector. Compliance verification is crucial to ensure that any potential hazards are addressed and that the installation is safe for continued use.
