If you’re looking to meet IECC 2012/2015, ASHRAE 90.1 2013/2016 or Title 24 2016 commercial energy control requirements, you’ll need to familiarize yourself with receptacle control. All the big three energy standards require controlled receptacles, which respond to control signals (such as occupancy sensors or building schedulers) and keep non-essential electrical loads (small appliances, phone chargers) switched off when spaces are vacant or closed.
When you factor in new National Electric Code (NEC) requirements for Class 1 and Class 2 wiring devices, simple plug load control can quickly become more complicated. Fortunately, we’re here to break down the requirements and meet them all with the simplest solution possible.
When do I need receptacle control?
That largely depends on what your application is and where the facility is located.
What does the NEC say about receptacle control?
While the NEC does not directly address receptacle control, it does regulate Class 1 and Class 2 wiring devices. Receptacle control usually requires a power pack, which is typically a Class 2 device.
Class 1 Circuits are divided by the NEC into two types:
Class 2 circuits have power limitations for the power sources:
What do I need to do to meet code and install a controlled receptacle with a power pack?
Although many power packs, including the Leviton OPP20 power pack, are Class 2 devices, they can achieve compliance and be reclassified as Class 1 by following these simple steps:
