TL;DR
A garage penetration seal is the fire-resistant closure required where an EV-charger circuit, conduit, or cable passes through the wall or ceiling separating an attached garage from the dwelling, restoring the gypsum separation the IRC mandates between garage and living space. Installers pack the annular space with fire caulk or use listed putty pads and grommets rather than leaving raw drilled holes.
What it means
A garage penetration seal is the fire-resistant closure required where an EV-charger circuit, conduit, or cable passes through the wall or ceiling separating an attached garage from the dwelling, restoring the gypsum separation the IRC mandates between garage and living space. Installers pack the annular space with fire caulk or use listed putty pads and grommets rather than leaving raw drilled holes. It is a small detail inspectors reliably check on charger permits because the garage separation exists to slow a car-fire's spread into the house.
