What is the difference between a periodic inspection and a new installation inspection?

The distinction is rooted in the purpose and objectives of each type of inspection. A periodic inspection focuses on evaluating and maintaining the safety and functionality of existing installations over time. Its goal is to identify any wear, damage, or code deviations that may have developed since the last inspection, ensuring the system remains safe and reliable.

In contrast, a new installation inspection is conducted to verify that a recently installed electrical system conforms to current regulations, standards, and safety requirements. This type of inspection is crucial for confirming that the new installation is safe for use and has been executed correctly from the outset.

The other options misrepresent the scope or nature of these inspections; for example, suggesting that a periodic inspection is only for commercial buildings disregards its applicability to residential and other types of properties. Similarly, claiming a new installation inspection includes existing systems misrepresents the focus of these inspections, which is on evaluating new work only. The mention of energy audits within periodic inspections does not universally apply and does not encapsulate the primary aim of that type of inspection.
