Phoenix 400A Panel Engineering

I’m upgrading a residential property to a 400-amp service and need a complete, permit-ready package that satisfies the City of Phoenix review. I will rely on your Arizona-licensed stamp to get the plans through the first cycle with no corrections.

The work includes:
• Electrical drawings for the new 400 A main panel
• NEC-compliant load calculation for the residence
• Single-line (one-line) diagram showing feeders, grounding, and protection
• Site plot plan highlighting all utility lines on the lot
• Your professional engineer seal and signature on every sheet
• Final delivery in both PDF (ready for e-submittal) and native AutoCAD

All sheets should follow the city’s title-block requirements and be laid out on 24 × 36 paper size. Please factor in any local amendments to the NEC that Phoenix enforces; the goal is zero redlines.

Let me know your estimated turnaround and the number of plan-review cycles you’ll stay engaged for.
