Sub Panel Install with Fire-Rated Wall and AFCI Protection

A lot of homeowners don't think about their electrical panel until something goes wrong. Tripped breakers, not enough circuits for a remodel, outlets that can't keep up - these are signs your system needs attention. Adding a sub panel is one of the smartest ways to expand capacity without overhauling your entire electrical setup.

Here's what we were working with on this one. The sub panel needed to go into a wall that required proper fire-rated construction around it - not just drywall slapped up and called good. We built it out the right way, with a fire-rated wall assembly surrounding the panel enclosure. That detail matters more than most people realize. If something ever goes wrong inside that panel, that barrier is doing real work to slow the spread.

We also loaded this panel with AFCI breakers. Arc-fault circuit interrupters are designed to detect dangerous electrical arcs - the kind that can ignite a fire inside your walls before you ever see or smell anything. They're now required by code in most living spaces for good reason. Getting them installed here means this system isn't just functional, it's genuinely safer than a lot of what we run into in the field.

The finished result is a Siemens sub panel seated flush in the fire-rated wall, cleanly wired, labeled, and ready for the circuits it needs to serve. Code-compliant from top to bottom. When you're planning a room addition, garage conversion, or any project that needs dedicated circuits, this is the kind of foundation that sets everything else up for success.

Panel upgrades and sub panel installs are something we do regularly - and we take the details seriously every time. The fire-rated assembly, the right breakers, the clean wiring - none of that is optional in our book. If your home is running out of capacity or you're planning something that needs more power, we're the team to call.
