A designer prepares a permit package for an 8-kW home rooftop system with a supply-side tap. The city plan check asks for layout, wiring, and safety labels in one submittal. Which permit document package should the designer submit to show code-compliant electrical layout?

The complete package includes the documents needed to review the physical arrangement, electrical connections, and required safety markings: the site plan locates the system, the roof layout shows module placement, the single-line diagram depicts the electrical configuration, the placard schedule identifies labels, and equipment specifications support review of the selected components. A package with the site plan, single-line diagram, placard schedule, and equipment specifications but no roof layout leaves the reviewer unable to verify the array’s placement and arrangement on the building. A package with the site plan, roof layout, placard schedule, and equipment specifications but no single-line diagram cannot show the conductors, overcurrent protection, or interconnection; a plan view is not a substitute for the electrical schematic. A package with a single-line diagram for a load-side breaker connection documents the wrong configuration for the stated supply-side tap, even when the other expected document types are included. Exam caveat: permit submittal checklists vary by jurisdiction, and a supply-side connection may trigger additional local details or utility coordination requirements. Practical check: confirm that the single-line diagram explicitly identifies the supply-side tap and associated service equipment, then cross-check its ratings and required placards against the equipment schedule and applicable local checklist.
