Inside a Span Panel Install: From Empty Box to Smart Home

April 2, 2026 5 min read By Holsen Solar

What Does a Span Panel Install Actually Look Like?

Most homeowners have never seen the inside of their electrical panel — and for good reason. It's not exactly inviting. But when we replace an old breaker box with a Span smart panel, the transformation is worth documenting.

We recently completed a full residential panel swap through our electrical division, Lyons Electric. Here's what the process looks like from start to finish.

The Process

Step 1: Mount and prep. The Span enclosure goes up on the wall and all existing home wiring gets pulled into the new panel. At this stage it looks like controlled chaos — dozens of loose wires waiting to be terminated.

Step 2: Organize. Every wire gets identified, labeled, and routed to its correct position. This is where experience matters — a clean wire layout means easier troubleshooting for decades to come.

Step 3: Breakers go in. Span uses standard Square D Homeline breakers — nothing proprietary. All the intelligence lives in the circuit control board behind the breakers, which monitors and controls each circuit individually.

Step 4: Dress and verify. All wiring gets tidied, connections are torqued to spec, and every circuit is tested. This is the step most people skip when they rush — we don't.

Step 5: Power on. The moment the main breaker closes and the Span panel lights up. The LED backlight and circuit indicators come alive — every circuit is now visible and controllable from your phone.

Step 6: Button it up. Cover goes on, final inspection passes, and the homeowner gets walked through the Span app. From the outside, it's a clean white panel. From your phone, it's total control over your home's energy.

Why Span?

A traditional breaker panel is a dumb switch — it either sends power or it doesn't. Span gives you:

  • Circuit-level control from your phone — turn any circuit on or off remotely
  • Energy monitoring — see exactly what each circuit is consuming in real time
  • Smart backup — when paired with a battery, choose which circuits get backup power during an outage and change priorities on the fly
  • Solar optimization — maximize self-consumption by intelligently managing loads
  • EV charging management — prevent panel overloads when your car charges at night
