Electrical Equipment Centers
Application Considerations

Testing Customer can complete many
pre energization tests before
installation. Witness testing can
be at one location. Each type of equipment is tested
at different factories. Witness
testing requires more time and
travel
Changes Changes can be made after
functional testing and inspection
in controlled factory environment
Receiving, Handling, & Storage Arrives in single shipment,
usually unloaded in one hour; can
be stored indefinitely as integral
unit, inherently protected against
elements Purchaser must provide for
receiving and storing multiple
units made at different times by
different suppliers. Often
involves redundant handling for
storage, trucking to intermediate
locations, and protection during
storage form pilferage or other
loss, or lost time due to weather
Installation Involves minimum number of
crafts Requires many crafts; i.e.,
carpenters, ironworkers, cement
finishers, brick layers,
electricians-all with foremen and
helpers
Expansion Modular construction results in
convenient expandability as
system grows Space for expansion must be
included initial installation
Commercial Treatment Taxed same as weatherproof
equipment Treated as real estate
improvement necessitating higher
tax schedule, building permits,
progress inspections, bonding &
insurance
Special Applications
equipment center's can be designed for high wind loading (up to 150 MPH), seismic Zone 4 applications, and high
snow loading. Fire proofing can be installed on exterior walls to protect switchgear from transformer failures. Special
exterior finishes can be provided to better integrate equipment center with surrounding environment. Offices,
bathrooms, maintenance rooms, battery rooms, etc. can be added to equipment center to eliminate additional buildings
at site.
