Building Inspector''s Guide
The NEC690 Building Inspector''s Guide is a set of reference materials developed for Building Inspectors and AHJ Officials as it relates to Article 690, of the National Electrical Code (NEC
Section 690.5 covers the ground fault detection/interruption for the PV system and requires a warning label on the utility-interactive inverter or near the ground-fault indicator at a visible location. Most often, these labels are applied on the inverter by the manufacturer. See Figure 1. Figure 2.
Here is a quick summary of PV system marking and labeling requirements. Section 690.5 covers the ground fault detection/interruption for the PV system and requires a warning label on the utility-interactive inverter or near the ground-fault indicator at a visible location. Most often, these labels are applied on the inverter by the manufacturer.
Installers should consult the National Electricians Code (NEC) regarding PV systems and any local regulations from cities and municipalities. The basic parts of a PV system that need labels and warning signs include the following: Now that we know what needs labeling, we'll explore the PV labeling requirements that installers need to know.
There are many PV system marking and labeling requirements in the NEC. Some markings will be factory applied as required by the product listing and others must be field applied by the installer. Figure 1. Warning label on inverter.
When the photovoltaic system also has batteries, the same warning shall also be applied by the installer in a visible location at the batteries. IBTS INTERPRETATION: A warning label shall be applied to the Inverter or near the ground fault indicator describing the hazard that would exist in the event of a ground fault.
They're also crucial for maintenance and repairs of the solar PV system after installation. Maintenance and repair workers rely on up-to-date and accurate labels to ensure their safety and help them work efficiently. We've established that warning labels and signs are important to PV systems.
