What is one of the key installation requirements for Class 2 circuits?

Class 2 circuits are designed to operate safely and efficiently at lower voltage levels, typically under 60 volts, with limited power output. One of the key installation requirements for these circuits is that they should be protected from physical damage. This means that the wiring and components associated with Class 2 circuits must be installed in a manner that reduces the risk of mechanical injury or environmental factors that could compromise their integrity.

Such protection can include routing the cables through conduits, using non-conductive enclosures, or positioning the cables in areas where they are less likely to be inadvertently disturbed. By safeguarding these circuits from physical risks, it helps maintain the safety of the installation, reduces the likelihood of short circuits, and ensures that the low voltage communication systems function properly without interruption or hazard.

While secondary grounding, current limitations, and labeling are important considerations in electrical work, the specific emphasis on physical protection underscores the need for safety in environments where low voltage systems operate, making it a key requirement for Class 2 installations.
