PowerPoint® Presentation Chapter 13 Permitting and Inspection Building Codes and Regulations • Permitting • Inspection Chapter 13 — Permitting and Inspection Product standards, installation codes, and code enforcement are separate but related functions that result in better and safer installations. Chapter 13 — Permitting and Inspection There are several types of UL marks, each with a specific meaning. Chapter 13 — Permitting and Inspection PV equipment may bear the marks of listing and certification organizations other than Underwriters Laboratories. Chapter 13 — Permitting and Inspection Site drawings should be provided with permit applications indicating locations and providing descriptions of major components. Chapter 13 — Permitting and Inspection Permit applications must include either a one-line or a three-line electrical diagram. Additional electrical information may be included as a separate document. Chapter 13 — Permitting and Inspection Specifications for PV modules, inverters, and other equipment are required for code calculations and compliance. Chapter 13 — Permitting and Inspection Descriptions and drawings of the array mounting design and materials are used to analyze the structural integrity of the structure and the array. Chapter 13 — Permitting and Inspection Building permits include information about the construction project and inspections, and must be posted in a conspicuous location. Chapter 13 — Permitting and Inspection Quality workmanship results in a neat and efficient electrical installation. Chapter 13 — Permitting and Inspection Dedicated space is the clear space reserved around electrical equipment for the existing equipment and potential future additions. Chapter 13 — Permitting and Inspection Working space is the clear space reserved around electrical equipment so that workers can install, inspect, operate, and maintain the equipment safely and efficiently. Chapter 13 — Permitting and Inspection Rubber or plastic terminal covers are used to prevent shorts across battery terminals. Chapter 13 — Permitting and Inspection PV module labels must include terminal polarity information and ratings for voltage, current, and power. Chapter 13 — Permitting and Inspection A label indicating the operating current, operating voltage, maximum system voltage, and shortcircuit current must be displayed at the DC disconnect of a PV array. Chapter 13 — Permitting and Inspection Labels identifying the PV system as a power source and including its maximum output operating current must be posted at the AC disconnect of a PV system. Chapter 13 — Permitting and Inspection PV systems with batteries must have labels indicating the battery maximum operating voltage, equalization voltage, and polarity of the grounded circuit conductor. Chapter 13 — Permitting and Inspection Single 120 V supply panelboards must be marked to prohibit connection of multiwire or 240 V branch circuit loads. Chapter 13 — Permitting and Inspection Maintenance or operation labels are recommended for detailing nominal equipment settings and adjustment procedures.
