Grocery stores and fueling stations must be kept open. Inspection by the Building Department is involved at some point for all of these critical functions.
How do we as electrical professionals promote the need for this electrical working space so that panelboards remain readily accessible?
Several different wiring methods may be used to route the power from the PV array to the utilization equipment.
