I just build or repair electrical equipment! Why do I have to be a QEW?

Most importantly, when you build or repair a piece of equipment that you or others will use, you have a responsibility to provide equipment that is safe for its intended use. You have a big responsibility, as you become responsible for someone’s health and life! Part of being a QEW is being familiar with the construction and operation of equipment; that familiarity allows you build or repair equipment responsibly.

Additionally, equipment is required to be built and/or repaired according to numerous applicable codes and standards, such as those produced by UL (Underwriter’s Laboratories), IEEE (Institute of Electrical and Electronics Engineers), and NFPA (National Fire Protection Association), just to name a few. A person who builds or repairs equipment must be knowledgeable these standards and requirements. Approval as a QEW helps ensure that a person has this knowledge.
