Rule 819. Sections 80.21, 80.21.1, and 80.21.2 are added
to the code to read as follows:
80.21.
Plans required. An applicant shall submit a detailed set of plans and
specifications with the application for an electrical permit for wiring or
alteration to an electrical system if the system requires installation of
electrical equipment that has an ampacity of more than 400 amperes, at 1,000
volts or less, for the service or feeder and if the calculated floor area in a
building is more than 3,500 square feet. The enforcing agency may request plans
for projects that include an unusual design. Plans and specifications shall
conform to the following:
(a) Lighting
layout.
(b) Circuiting.
(c) Switching.
(d) Conductor and raceway sizes.
(e) Wattage schedule.
(f) Service location and riser
diagram.
(g) Load calculations and
available fault current calculations.
(h) A proposed method of construction that is
drawn with symbols of a standard form.
All conductors are assumed to be copper unless otherwise
stated in the plan. Specifications, when provided, shall also include the
information listed in this rule. The selection of suitable disconnect and
overcurrent devices to provide proper coordination and interrupting capacity
for a wiring system is the responsibility of the designer. The enforcing
agency, when approving electrical plans, does not assume responsibility for the
design or for deviations from electrical drawings. The permit holder shall
ensure that the plans and specifications approved by the enforcing agency, or a
certified copy of the plans and specifications, where required, are available
on the jobsite for the use of the enforcing agency.
80.21.1. Plan revisions. Work shall be
installed pursuant to the code and approved construction documents, and changes
made during construction that are not in compliance with the approved
construction documents shall be resubmitted for approval as an amended set of
construction documents.
80.21.2.
Information on construction documents. Construction documents shall be
dimensioned and drawn on suitable material. Electronic media documents may be
submitted when approved by the enforcing agency. Construction documents shall
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 provisions of this
code and relevant laws, ordinances, rules, and regulations as determined by the
enforcing agency.
