An electrical fitter designs, constructs, and maintains wiring in settings ranging from individual residences to power plants. Before beginning professions in electrical fitting, people must complete training. Depending on the country, this could entail a four-year apprenticeship, followed by a certification test to verify knowledge of electrical wiring and associated topics. Rates of pay are determined by the workplace and any specialised credentials an individual holds.

Understanding different-sized electrical systems and circuits as well as the local electrical code are requirements for employment as an electrical fitter. A fitter can design a new installation from scratch or evaluate an existing one to check whether requirements are being met and if there are any safety or efficiency issues. Electrical fitters may work as independent contractors or for bigger businesses and may be eligible for employment benefits including pensions.
