SYSTEM INSTALLERS should pay particular attention to the codes and
regulations governing PV installation. Doing so will ensure safety and
avoid having to redo noncompliant installations. The Occupational Safety
and Health Administration (OSHA) regulations and National Electrical
Code (NEC) practices are essential guidelines for PV installation. Under-
standing the codes and regulations are important tools to preventing job-
related incidents such as electrical hazards, injuries, or even death. Failure
to follow codes and regulations can result in a loss of time and money if
you have to reinstall the system.
This chapter focuses on building codes and regulations for PV systems.
It also will take a closer look at labeling PV equipment and systems.

Working safely with PV systems requires following rigid safety practices.
Approach every installation step with common sense. All workers on a
project site must follow safety guidelines at all times.
Construction sites are dangerous by nature.

installed, safely built PV systems can be hazard- and incident-free.
