structure. For the purpose of this rule, "complex structures" have an
electrical system designed, constructed or reconstructed with any of the
following:
(a) A service or feeder beginning
at 400 Amps where the available fault current exceeds 10,000 Amps at 150 Volts
or less to ground or exceeds 14,000 Amps for all other installations;
or
(b) Installation of a 150 KVA or
larger separately derived system as defined in Article 100 of the
National Electrical Code (NEC); or
(c) Addition of a new motor load of 100 HP or
more; or
(d) Fire pump
installations as defined in Article 695 of the NEC; or
(e) Emergency systems installations as
defined in Article 700 of the NEC; or
(f) A service or feeder rated at 600 Amps or
over; or
(g) Voltage. More than 600
supply volts nominal; or
(h)
Renewable Energy. Renewable electrical energy systems rated over 25 KVA;
or
(i) Height. More than three
stories; or
(j) Occupancy.
(A) Six or more residential units in one
structure; or
(B) An "A" (Assembly)
occupancy, "E" (Educational) occupancy, or "I-2" or "I-3" (Institutional)
occupancy as defined in the adopted Oregon Structural Specialty

(C) Any of the
following special occupancies as described in Chapter 5 of the NEC adopted by
the board in OAR 918-305-0100:
(i) Hazardous (Classified) locations as
defined in Articles 500 to 516; or
(ii) Installations in patient care areas of
health care facilities as defined in Article 517; or

(2) Plan review is
not required for work permitted through minor installation labels under OAR
918-309-0210 to
918-309-0260.
(3) A jurisdiction requiring electrical plan
review may not require plan review on more than one building or structure under
construction or reconstruction at the same job site, as long as:
(a) The electrical systems of the buildings
or structures are materially alike, and;
(b) A person obtains electrical permits for
the buildings or structures within a reasonable time.
(4) Standardized Format for Plan Review. When
electrical plan review is required the electrical plan shall meet the following
requirements:
(a) Copies. Submit two sets of
electrical plans;
(b) Readability.
The plans shall be drawn to scale, contain definitions for legends used, be of
sufficient clarity to indicate the location, nature and extent of the work
proposed and show in detail that it will conform to the applicable electrical
code requirements, laws, ordinances, rules and regulations;
(c) Contents. The plans shall contain the
following minimum requirements:
(A) Feeder
riser diagram showing panel location and circuit schedules;
(B) One line riser diagram showing bonding
and grounding and conductor sizes;
(C) Available fault current on the line side
of service disconnect;
(D) Complete
load calculations, or provide applicable load records, for all new
installations and for additions to existing installations;
(E) Fixture schedule, showing type, location
and layout of the fixtures;
(F)
Address of the installation and name of owner and address;
(G) Identification of the employer,
identification and signature of person who prepared the plan, license number if
the person is an electrical supervisor and professional registration number if
the person is an architect or registered professional electrical engineer;
and
(H) Location of emergency
systems, identifying the power source and the system on plan.
(5) Nothing in these
rules shall prohibit a jurisdiction from requiring a lighting energy
budget.
(6) Nothing in these rules
shall prohibit the owner or the owner's agent from requesting and receiving
plan review for non-complex structures.
