Welcome to the Leviton Blog > Green > Get in Control of Plug Loads and Receptacles section of the Leviton Blogsite. This section has the following description: In this modern age, it feels like we’re constantly getting more and more gadgets that require wall receptacle power. While crowded wall outlets are increasingly common, what’s less understood is the potential to save energy by controlling what we’re plugging in. One simple and efficient way to improve energy efficiency is Receptacle Control, also known as Plug Load Control, which automatically turns off plug loads when a space is vacated.What are Plug Loads? Plug loads include devices that plug into a standard electrical outlet, often called “standby” or “vampire” loads. Products not in use or on standby account for as much as 25 percent of total electrical consumption in commercial buildings. These products typically still draw power even in an off state. Examples include:Task lightingComputersMonitorsCell phone chargersPersonal fans/heatersA/V equipmentSmall appliances (toasters, coffee makers)Any electronic devices that can be switched off at night without causing harmful consequences are perfect candidates for plug load control. Meet the CodesIt’s not just smart, it’s the code! Energy codes now require Receptacle Control or Plug Load Control. Both ASHRAE Standard 90.1 2010 and California Title 24 2013 require controlled receptacles to have the same automatic shutoff function as lighting using either occupancy sensing or schedule based control. Plug-in strips and devices cannot be used for code compliance. Title 24 also requires the controlled receptacles to be permanently marked to differentiate them from uncontrolled receptacles.Receptacle Control Strategies Occupancy Sensing Based Receptacle Control Controls that monitor a space’s state of occupancy and will energize and de-energize a controlled receptacle based on occupancy.
