Energy Harvesting as a solution for NEC 2023 guidelines and improved energy efficiency

Since 1897, the National Electrical Code (NEC) published by NFPA 70 has been authoritative guideline for electrical safety in the US. It is critical for electricians in the U.S. to ensure safe electrical practices in residential, commercial and industrial areas.

NEC 2023: New challenges for battery-powered switches

The NEC 2023 update brings new regulations, especially for wall-mounted devices:

• Fail-safe mechanism in case of battery failure in switches or control sensors
• Increased safety in habitable rooms and hospitality spaces
• Constant power supply for wall-mounted switches, even if the primary battery fails

These requirements pose challenges for conventional battery-powered switches, as they require additional cabling despite the risk of fire. Electrical distribution or lighting systems are a major cause of house fires, often due to incorrect installation or overloading.

Energy Harvesting: The wireless, batteryless solution for energy efficiency

In response to these strict regulations, energy harvesting light switches are proving to be the only compliant wireless solution. These devices:

• Meet safety standards
• Offer improved energy efficiency
• Promote sustainability

Energy Harvesting technology harvests energy from various sources, including room light, temperature differences, and magnetic fields. This results in:

• Reduced reliance on copper and PVC in walls
• Minimized power consumption
• Reduced environmental impact
• Increased sustainability

EnOcean: Pioneering Energy Harvesting Technology

For over two decades, EnOcean has been a pioneer in energy harvesting technology, producing maintenance-free wireless switches and sensors. The foundation for safe and sustainable light switches is based on:

• Miniaturized energy converters
