2013 California Energy Code Title 24, Part 6: Separation of Electrical Loads

Another requirement of Title 24 is the separation of electrical loads for the purposes of metering or as stated in the code “designed to permit the disaggregated measurement of electrical load energy downstream from the service meter…” although the sub metering itself is not mandatory. These groups include HVAC, lighting, receptacles, water system pumps, elevators and similar, renewable energy sources, car chargers, and some other large loads. The requirements to segregate the loads becomes more strict as service size increases and Table 130.5-B clarifies these requirements. So what this will mean in general is more electrical panelboard hardware and less flexibility in moving around electrical loads. Service metering is also required and these requirements are identified in Table 130.5-A. Of course there are exceptions to these requirements so make sure to check the entire Section 130.5 but overall this section is rather thin at only 1-1/2 pages plus tables so its a quick read. The execution of the requirements is a bit more complex so plan for a bit more thought designing the distribution hardware and layout of equipment during programming and design.
