Commercial Wire
This course provides an in-depth comprehension of
commercial wiring. It includes the understanding of
electrical power needs and distribution requirements for a
typical commercial facility. The course stresses the
application of main power components to support
calculations necessary to have a safe and efficient
commercial installation. Students will become knowledgeable
of wiring for special circuits, appliances and loads
such as, but not limited to, refrigeration, HVAC, food
preparation apparatus and associated loads relative to
various types of commercial wiring. The course will
include requirements for a thorough study of commercial
service entrance equipment from the utility company’s
service drop to the building’s main switchboard.
Upon successful completion of this course, students
should be able to:

make connections.
• Identify and comprehend entrance grounding
requirements.
• Determine the preferred and required minimum size
conductors for lighting, appliances and general purpose
branch circuits.
