Nec Solar Panel Requirements

These drawings based on 2011 nec 690 requirements and contents on the 03 500 pack.

Nec solar panel requirements.

The international codes i codes are the widely accepted comprehensive set of model codes used in the us and abroad to help ensure the engineering of safe sustainable affordable and resilient structures. Section 690 of the nec solar photovoltaic pv systems includes all information regarding solar systems. Solutions for 2017 2014 and 2011 nec solar labeling requirements. 690 12 is the part of the nec that specifies the rapid shutdown requirements.

Building inspector s guide nec 690 pv labeling requirements 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 2014 for photovoltaic warning labels. Exposed non current carrying metal parts of pv module frames electrical equipment and conductor enclosures must be grounded. It also added few more details such as clarifying that this requirement does not apply to stand alone ground mounts. If you live in an area of the country that is under nec 2014 the code calls for the rapid shutdown switch to reduce the voltage to 30 v within ten seconds of all conductors leaving the ten foot boundary of the array.

The international code council icc is a non profit organization dedicated to developing model codes and standards used in the design build and compliance process.
