The California Office of Statewide Health Planning and Development (OSHPD) has prescribed its own connected load policy to facilitate the rapid deployment of electrical equipment in medical facilities. This accelerated procedure, outlined in OSHPD Policy Intent Notice (PIN-38) allows for the conduct of a 72-hour load study to confirm the capacity of feeders whenever loads are to be added to existing panels “for other than where loads consist of primarily x-ray equipment or motors.”

Bruce sez, quoting from PIN-38, “OSHPD will require two levels of load capacity verification. Level-one is the panel or branch circuit to which load is being added, its supply conductors, and its overcurrent protective device. Level-two is the next panel which is electrically upstream towards the source from the panel or branch circuit where load is to be added, including its feeder and feeder overcurrent protective device."  This 72-hour test is conducted twice, once before the equipment is installed and once after installation.

Metsys current logger demo2The ideal tool for conducting a connected load study is the METSyS Panel Capacity Analyzer (PCA), exclusively available in North America from POWERetc. The device has a built-in, rechargeable battery providing operation for a minimum of 72 hours (adequate for OSHPD studies). The graph below is taken from POWERetc’s proprietary report generator designed to take the data recorded and produce a complete report including details of planned load additions and removals.
