Who is required to have an electrical license according to the RCW?

The requirement for an electrical license according to the Revised Code of Washington (RCW) encompasses both individuals and firms. Individual electricians are required to have a license to perform electrical work, ensuring they meet the necessary qualifications, safety standards, and knowledge related to the industry. Additionally, firms and corporations must also possess the appropriate licenses to legally operate and provide electrical services. This dual requirement helps regulate the profession by ensuring that both the individuals performing the work and the companies that employ them adhere to the established codes and standards.

In the context of the other options, individual electricians (only) would not capture the responsibility placed on businesses, while technicians working under supervision typically operate under the license of a qualified electrician or firm, not requiring a separate license. Simply stating firms and corporations alone omits the vital aspect of individuals’ licensing, which is critical for both safety and legal compliance in electrical work. Therefore, the comprehensive answer is that both individuals and firms are required to be licensed to ensure the integrity and safety of electrical practices in Washington State.
