The business storywho it is for, what was broken, and how it runs
Who this is built for
Residential and commercial electrical contractors (1 to 20 vans) quoting EV charger installs, whole-home generators, 200A panel upgrades, recessed lighting, and troubleshooting.
What was broken
A master electrician spends 90 minutes driving across town to give a "free estimate" on a Tesla Wall Connector or hot-tub circuit—only to open the garage and find a maxed-out 100-amp panel on the opposite side of a finished basement, or a recalled Federal Pacific Stab-Lok panel that requires a $3,500 panel swap the homeowner wasn’t expecting.
How the AI agent workflow operates
When a homeowner calls or texts for an EV charger, generator interlock, or panel quote, the agent answers in 30 seconds and sends a guided photo link asking for 3 safe, closed-cover photos: (1) the main breaker handle showing 100A/150A/200A, (2) the breaker rows/brand label, and (3) a wide shot showing the distance from the panel to the install spot. The vision agent drafts a pre-visit scope brief for the estimator and runs automated 3-touch follow-ups on sent quotes.
What changed
Electricians give ballpark ranges or spot required 200A upgrades before rolling a van, reclaim ~12 hours a week from phone tag and unfollowed estimates, and close more high-ticket panel + charger bundles.

Step-by-step architecture4 stages with human approval gates
1 Stage 1Customer / Trigger
30-Second Call/Text Intake + Photo Link
Homeowner requests an EV charger, generator, or electrical repair; agent replies immediately and texts a 3-photo upload prompt.
2 Stage 2AI Agent
Closed-Cover Panel & Amperage Vision Check
Reads main breaker amperage (100A/150A/200A), open vs. tandem breaker slots, panel brand (flagging Federal Pacific, Zinsco, Challenger), and approximate conduit run.
3 Stage 3System / Tool
Estimator Brief & Good-Better-Best Quote Prep
Generates a structured scope note in Jobber / ServiceTitan (e.g., "Standard 50A circuit vs. Load-Management Device vs. 200A Panel Upgrade").
4 Stage 4Human Approval Gate
Electrician Quote Review & 3-Touch Follow-Up
Licensed electrician reviews/approves the estimate; the agent follows up automatically at Day 2, Day 5, and Day 10 until booked.
Upload a photo of a homeowner’s breaker panel (with the inner cover ON, door open) into Claude or ChatGPT with this prompt to generate an estimator pre-screen.
You are a Master Electrician’s Estimating Assistant.
Analyze the homeowner's photo of their electrical breaker panel (door open, dead-front cover ON) and their project request (e.g., Level 2 EV Charger, 50A Generator Inlet, or Hot Tub circuit).
### Strict Safety Rule
NEVER instruct a homeowner to remove the metal dead-front cover, touch internal bus bars, or test live lugs.
Output a 4-part Estimator Pre-Screen Brief:
1. MAIN SERVICE & PANEL IDENTIFICATION
- Main Breaker Rating visible (e.g., 100A, 150A, 200A, or split-bus).
- Panel Brand / Series (specifically flag if it resembles Federal Pacific Stab-Lok, Zinsco/Sylvania, Challenger, or Pushmatic).
2. SLOT AVAILABILITY & LOAD INDICATORS
- Count of visible open spaces vs. existing large 2-pole loads (Range, Dryer, HVAC, Subpanel, Water Heater) and tandem breakers.
3. PRELIMINARY SCOPE OPTIONS FOR ESTIMATOR
- Option A (If capacity/slots exist): Standard circuit install + approximate material checklist.
- Option B (If 100A or full): EV Energy Management / Load-Shedding device (e.g., DCC / Wallbox power meter) OR 200A Heavy-Up / Subpanel option.
4. 3 QUESTIONS TO CONFIRM WITH HOMEOWNER BEFORE SITE VISIT
- Distance from panel to install location, finished drywall vs. open garage/basement path, and utility provider.
