What You Need to Know about the NEC 408.9 Code Change for Panelboard Retrofits

  • Post category:Panelboards

Recently, the NEC updated its rules for retrofitting panelboards. Take a moment to get to up to speed and discover EMI’s code-compliant solution for panelboard retrofits.

NEC Article 408.9 Code Change Explained

The NEC made a critical update to Article 408.9: Replacement Panelboards. The 408.9 code change requires a new minimum box size rating for certain panelboard retrofits. If the available fault current is greater than 10,000 amps, you must comply with the code’s new minimum box size. If the required box will not work with the panelboard you’re retrofitting, then you will need to replace the panelboard.

The new rule does not apply to panelboards where the available fault current is less than 10,000 amps.
