I will do standby generator and ats permit drawings with nec load calculation

Need a standby generator permit approved without back-and-forth?

I prepare permit-ready drawings for home standby generators and automatic transfer switches (ATS), built to the NEC edition your city has adopted.

What I cover:

• Whole-home or essential-load ATS (service-rated or load-side)
• Generator sizing with an NEC Article 220 load calculation
• Load-shed / smart load management plans
• Air-cooled and liquid-cooled units, natural gas or LP

Your permit set can include:

1. Site plan with generator location and clearances (manufacturer listing / NFPA 37)
2. One-line diagram: utility, meter, ATS, generator, panels
3. Conductor, breaker and conduit sizing
4. Grounding and neutral-switching notes (NEC 250 / 702)
5. Panel schedule and required warning labels
6. Gas pipe sizing table (Premium)
7. Equipment spec sheets compiled into the set
8. Revisions for plan-review comments

Send me site photos, your main panel label, the generator and ATS models, and the fuel type. I will turn them into a clean PDF permit set.
