The AI-native workspace for design review.
Design IQ reviews your engineering designs against your standards—surfacing issues your engineers can act on, faster than ever before.
Can you check if the GEC sizing on the one-line meets NEC 250.66 for this 200A service?
The GEC shown on E-101 One-Line D...p.4 is specified as #6 AWG copper. Per NEC 250.66, a 200A service with 3/0 AWG ungrounded conductors requires a minimum #4 AWG copper GEC.
The current sizing is non-compliant. I recommend upgrading to at least #4 AWG copper and updating the one-line diagram and grounding detail on E-101 One-Line D...p.12.
What about the service entrance conductor ampacity — does it pass 310.15?
The load calculation on E-101 One-Line D...p.2 shows 187A demand. The one-line specifies 2/0 Cu at 75°C which is rated for 175A. After applying NEC 310.15(B)(3)(a) derating factors, the conductors are undersized by ~12A.
Recommendation: resize service conductors to minimum 3/0 AWG copper to satisfy ampacity requirements, and update the one-line and panel schedule.
