This may not be the most popular topic but with the new 2016 version of Title 24 code there are exciting and important changes to discuss. The requirements for plug load control have remained rather the same, with a few major changes.
The biggest change for plug load control is the requirements in alterations. Alterations section 141.0(b)2 has a new subsection P (141.0(b)2P) that covers Electrical power distribution requirements in alterations. 141.0(b)2 Piv states that “Circuit Controls for 120-Volt Receptacles and Controlled Receptacles. For entirely new or complete replacement of electrical power distribution systems, the entire system shall meet the applicable requirements of Section 130.5(d).” The CEC has confirmed that this means that receptacle control is only required in alterations when the entire electrical distribution is replaced. Note, if replacing the entire distribution system, then all connected receptacle loads must meet the requirements of 130.5(d).
The areas/spaces where plug load controls are required are similar but listed with broadened terms. Private offices and open offices have been changed to Office Areas, to include any space that has office related functions being performed. This includes any room or area of a building in CBC Group B Occupancy where business, clerical or professional activities are conducted, including quiet rooms, warehouses, etc., where these functions are also performed. “Reception lobbies” was changed to Lobbies to include all lobbies within a building or space. The term Kitchenette was broadened to Kitchen Areas as to include any space within a building where there are cooking facilities or where food is prepared. Conference Rooms and Copy Rooms have remained unchanged. Hotel and motel guest rooms maintain the same requirement to control half of the receptacles using a captive keycard, occupancy sensing control, or automatic controls that switch the power off no longer than 30 minutes after the guestroom has been vacated.
The requirements for plug load control are still to install a control system: that can automatically shut off the lighting when the space is typically unoccupied, with an automatic holiday shut-off and maximum 2-hour override. At least one controlled receptacle must be installed within 6 feet of an uncontrolled receptacle or split wire the receptacles to provide at least one controlled and one uncontrolled receptacle. Modular furniture in open office areas are to have at least one controlled receptacle installed at each workstation. Provide controlled receptacles or circuits with a permanent and durable marking that differentiates them from other uncontrolled receptacles or circuits.
