The Oregon Electrical Specialty Code
(OESC) is found in Oregon Administrative Rule
Division (OAR) 918-305.
The OESC consists of the 2014 NEC, Oregon
amendments, Statewide interpretations and
Statewide alternate methods. Special
permission and site specific alternate methods
can be approved by the local Building Official.

On April 1st 2014, rules changed allowing a CAE
certified inspector to inspect individual dwelling
units of apartment buildings covered by the
Low-Rise Residential Specialty Code and
attachment of structural components of a photo-
voltaic (solar) installation.
Electrical plan review is not allowed under this
certification.

requirement to have job.
(b) Action affects everyone in the class equally.
(c)Membership is related to a tax-exempt nonprofit
corporation

2014 OESC Residential Inspector Code Checklist
and Useful Information
EXAMPLE
PART 1 – SERVICE and GROUNDING 2014 NEC®/ OESC
of 44 24
The Checklist is used to help the student
quickly find code references to meet the
requirements of OAR 918-098-1900. The
checklist can be added to in the field when
repeat items are found. The checklist is
designed to be a living document that is
modified as new issues are brought forth and
to aid the inspector as a active tool in the
inspection toolbox.
of 44 25
Accela Inspector App
26
Inspectors can result and schedule inspections out in the field by using
the Accela Inspector App. Inspectors are able to add
comments and signatures to records as well as electronically send or print out an Inspection
Summary Report. Information in the Accela back office is linked with
the Inspector App.
You can download the Inspector App onto your iPhone or iPad by going to iTunes and searching for Accela inspector. The download is free and the Inspector App icon will
appear on your device once the download is complete.

If you are uncomfortable performing inspections
or uncertain of what you are doing seek
assistance.

Homework and Reviews are required to be
turned in by the assigned due date.
During the course of training, students are
encouraged to ask questions, for clarification and
if needed, to ask for additional tutoring. The goal
is to have the best, most competent inspectors
and to maintain the inspection focus on safety. It
is imperative that the student get out in the field to
apply the information learned in the class. The
instructor(s) ask questions during the class that
challenge student knowledge. Class participation
is required for all students.
of 44 31
During the training, as you are out performing
field training, take photos of unusual
installations or non-compliant installations for
sharing with the class.
Please do not include people or identifiers of
locations or contractors.

Ratio and Proportion
40
Ohms Law states the relationships between
voltage, current, resistance, and power.
The relationship that is most important to
electricians and inspectors is; P=IE
Power measured in watts is calculated in purely
resistive circuits as Current in Amps times Volts.
I is the symbol for current
E is the symbol for voltage
of 44
Ratio and Proportion (cont.)
41
Where the desired power is a given quantity, current and voltage are inversely proportional. This is why heavy loads like electric heat are typically
supplied by 240 volts instead of 120 volts. A 12,000 watt furnace designed for operation at 240 volts will
draw;
50 amps @ 240 volts 12kw @ 120 volts would draw 100 amps
