Any of you heard of "automatic receptacle control". What type of receptacle(or wiring) would this be?
Thinking controlled by occ sensor or the like. Just a random question I was curious about.
yes. For example this is from the Washington energy code:
C405.10 Controlled receptacles (Mandatory). At least 50
percent of all 125 volt 15- and 20-ampere receptacles
installed in private offices, open offices, conference rooms,
rooms used primarily for printing and/or copying functions,
break rooms, individual workstations and classrooms, includ-
ing those installed in modular partitions and modular office
workstation systems, shall be controlled as required by this
section. ((In rooms larger than 200 square feet (19 m2
),))
Either split receptacles shall be provided, with the top recep-
tacle(s) controlled, or a controlled receptacle shall be located
within ((72)) 12 inches
receptacle. Controlled receptacles shall be visibly differenti-
ated from standard receptacles using the standard symbol
required by the Seattle Electrical Code and shall be con-
trolled by one of the following automatic control devices:
1. An occupant sensor that turns receptacle power off
when no occupants have been detected for a maxi-
mum of 20 minutes.
2. A time-of-day operated control device that turns
receptacle power off at specific programmed times
and can be programmed separately for each day of
the week. The control device shall be configured to
provide an independent schedule for each portion of
the building not to exceed 5,000 square feet (465
m
2
) and not to exceed one full floor. The device
shall be capable of being overridden for periods of
up to two hours by a timer accessible to occupants.
Any individual override switch shall control the
controlled receptacles for a maximum area of 5,000
square feet (465 m2
). Override switches for con-
trolled receptacles are permitted to control the light-
ing within the same area.
