How to Understand NEC 700.12 and 700.17
Have you ever been in a building when the lights suddenly go out? Our modern building codes and standards ensure we are never left in complete darkness for more than a few seconds. For this, we can thank the National Electric Code’s (NEC) two sections—700.12 and 700.17.
In this guide, we answer questions, provide guidance, and address several topics such as:
- Discrete battery pack units or ‘bugeye’ fixtures
- Luminaires with integral battery packs
- When you might need ALCR
- Function and use cases for BCELTS
- Central inverter systems
- Generators and code requirements

Emergency lighting, which illuminates the path of egress from a building, is one of the most important systems we design, install, and maintain.
This guide will help you make decisions when considering backup power for emergency lighting. Considerations include selection of the right battery packs, battery systems, and generator systems for your next project.
