Which of the following is not a purpose of electrical codes?

The purpose of electrical codes primarily centers on safety, standardization, and performance. The guidelines established within these codes are designed to protect both individuals and property from electrical hazards, ensuring safety is the foremost concern. Standardization across electrical installations allows for uniformity, which is essential for safety and clarity, making it easier for contractors, engineers, and inspectors to understand and comply with requirements.

Furthermore, electrical codes aim to ensure that electrical systems perform consistently, which helps maintain reliability and efficiency in electrical installations.

While reducing installation costs might be a beneficial side effect of following codes—due to streamlined processes or materials—this is not a primary purpose of electrical codes. The focus is primarily on safety, standardization, and performance rather than cost reduction. Therefore, the assertion that reducing installation costs is not a purpose of electrical codes is accurate.
