U.S. Courts Design Guide
Electrical, Audio, Video, Communications, and
Data Transmission
An adequate number of electrical, data, and phone outlets must be placed near
anticipated locations of equipment (e.g., sound recording equipment, amplifiers,
video monitors, cameras, computers, projectors, x-ray viewers, court reporter steno
machines, etc.). Power capacity and distribution must accommodate future
requirements and take into account center, off-center, and corner bench locations.
Electrical Distribution
Normal. A three-phase, four-wire panelboard must be provided for each
courtroom. The panelboard must be sized to serve the courtroom, trial jury suite,
miscellaneous areas, and circulation spaces. The panelboard must serve all normal
lighting and general power requirements. If service is obtained by a three-phase,
480-volt supply, the general 120-volt power requirements must be served from a
480-120/208 volt transformer and associated panelboard. The local system ground
must be tied into the main building ground. The feeder serving the area must
accommodate 25% load growth.
Dedicated. An electrical distribution system with dedicated grounding and
independent breakers should serve computer and security-related equipment.
Designated Outlets. Minimum requirements for the various components of the
courtroom are as follows:
Judge's Bench
One quadriplex receptacle for general purposes at the judge's station
One dedicated computer power receptacle
Courtroom Deputy Clerk Station
One quadriplex receptacle for general purposes
One dedicated computer power receptacle
