OAR 820-040-0010: Electrical Engineering

(1) "Electrical engineering" is the design of the electric power, control, and fire and life safety systems with the following electrical services: (a) Below 250 volts, 96 Kva and above; (b) Above 250 volts, and less than 600 volts, 150 Kva and above; (c) Above 600 volts. (2) Example where the services of a registered engineer may be required include the design of electrical systems for the following: (a) Hospitals; (b) Nursing Homes; (c) Homes for Aged (with medical care and/or central dining facilities); (d) Retirement Homes (with medical care and/or central dining facilities); (e) Auditoriums (includes Concert Halls and Assembly Places for 100 or more persons); (f) Schools; (g) Gymnasiums; (h) Fraternal Buildings; (i) Structures under the purview of UBC 1807 with Oregon amendments; (j) Multi-family Dwellings; (k) Planned Unit Developments; (l) Retail Stores; (m) Office Buildings. (3) The Board recognizes that there may be some electrical systems in the above listed structures, which are not sufficiently complex to require the services of a registered engineer. These systems may be submitted to the Board prior to issue of a building permit, and the requirement for a registered engineer may be waived. (4) The design of electrical systems for the following structures are exempted from the requirements of subsection (1) of this rule: (a) Duplex dwellings and structures used in connection with or auxiliary to a single-family dwelling or a duplex dwelling. (b) Farm buildings and structures used in connection with or auxiliary to a farm building, public, commercial, industrial, or storage buildings where electric power use is limited to general purpose lighting, branch circuits not exceeding 60 amps, and the voltage not exceeding 250 volts. (c) Any electrical contractor whose practice includes the installation and fabrication of electrical systems which they install by virtue of a license issued under ORS 479.510 to 479.990, which requires an aggregate service capacity below that defined in subsection (1) of this rule is exempted from the requirements of subsection (1) of this rule.
