oven) may be able to be shifted
to the evening hours when elec-
tric rates are lower. Monitoring
how and when energy is used
reveals opportunities to reduce
energy usage by turning loads
off or adjusting the schedule of
when they operate.
3. Documenting
hazardous issues
To connect an energy logger, a
technician has to open and/or
remove the covers of disconnects,
motor control centers, panels,
switchboards and other types
of cabinets that aren’t accessed
very often due their high voltage
levels and the difficulty of pow-
ering down vital equipment. That
process creates an opportunity to
check the electrical equipment
for dangerous safety conditions
that may have evolved over time,
before they become disasters
(e.g. severely burnt insulation
on the conductor(s) feeding a
panel—a sign of an overload), or
serious electrical code violations,
such as fuses in a circuit that
are oversized for the conductors
they feed. Be sure to document
any hazardous issues found and
report them.
Safety note: technicians must
always wear the appropriate
personal protective equip-
ment (PPE) and follow all safety
regulations when working on
energized panels.
4. Performing short
job surveys
Load studies are often conducted
when there is a specific need
for additional power. Setting up
the energy logger to conduct
the study provides an excellent
opportunity to perform a short
job survey for the project in
addition to monitoring power
use—document potential locations
for the new panel, installation
issues, the number of hours
required to complete the project,
and necessary material.
