PLAN No. 1200. ELECTRICAL INSPECTION
Nearly all electrical installations are now subject to inspection. Most fire-insurance policies provide that electrical work in the insured building must be installed in accordance with the National Electrical Code, and insurance may be refused on any building not wired in accordance with the code. Sometimes in the country districts, installations are not inspected, but in the cities and in most industrial plants periodical inspections are made. Many cities have wiring codes of their own, which are enforced by ordinance and which are based on and are in general similar to the National Electrical Code.
To insure that the code rules are observed it is in most cities required that the wiring, fixtures, motors, and other electrical equipment be inspected by a municipal or an insurance inspector before electric service is given. Large industrial plants located outside the cities are examined by insurance inspectors.
Duties of inspectors.—The duties of the inspector are to scrutinize work in detail and, if it is properly installed, to approve it and recommend that a certificate of inspection therefor be issued. If it is not in accordance with the code, he suggests the necessary alterations. Upon the issuance of an inspection certificate, the local electric company is authorized to give service.
To handle his duties effectively, an inspector should have an extensive knowledge of electrical construction. Furthermore, he must be familiar with the wiring rules specified by local ordinance or by the code. The rules relate to signal systems, lighting circuits, power wiring, installation of motors and generators, high-tension machinery, transformers, switchboards, substations, and the like. In every municipal underwriters’ inspection organization, it is often necessary to make rulings relating to features of electrical work which are encountered infrequently and which are, therefore, not covered in detail in the regular printed rules. The inspector must also be familiar with these. In other words, he must know after inspecting a job whether or not it has been installed in accordance with the “Code” under which he is working. Ordinarily this knowledge can be obtained satisfactorily only through extended experience in electrical construction.
Opportunities for disabled men.—Possibilities offered by electrical inspection for returned soldiers are very promising. The inspector spends probably half of his time out of doors and half indoors in finished buildings. In the larger cities, inspectors are usually provided with motor cars so that they can move quickly from job to job. Little physical exertion is required, and there is no lifting or pulling. But an inspector should be able to climb around buildings under construction, and into attics. Both hands are required for testing, but one arm may be artificial. A returned soldier who has had previous electrical-construction experience, but who because of some physical disability can not follow his old vocation, should find electrical inspection a means of earning a good livelihood at interesting work.
The work is normally eight hours per day, with Saturday afternoons off but, since the men are usually paid monthly salaries, sometimes they will do little work on one day and have to spend overtime on the next. Theoretical training in a school which teaches electric wiring is very desirable for a man who has not made a study of the code requirements. The salary for an inspector will range from $100 to $175 per month. A chief inspector to whom several men report may receive from $150 to $250 per month and possibly more. In some cities the wiring inspectors must be members of the wireman’s union and receive the prevailing rate of pay for wiremen.
