Question 1

Can AI help with NEC load calculations?

Accepted Answer

Yes — AI tools like ChatGPT can assist with NEC Standard Method (220.82) and Optional Method (220.84) load calculations. Engineers prompt the AI to walk through the demand factor tables, apply the correct multipliers for appliances and HVAC, and format the results. Python scripts can automate the full calculation given inputs. The key is treating AI as a copilot that accelerates the workflow, while the licensed EE verifies and stamps the final result.

Question 2

What AI tools are most useful for protection coordination studies?

Accepted Answer

ChatGPT and Claude are most useful for interpreting ETAP/SKM study outputs, generating relay setting documentation, and looking up IEEE 242 (Buff Book) and IEC 60255 curve equations. Python (with pandas and matplotlib) can automate TCC curve plotting. AI assistants help draft the coordination philosophy narrative and flag potential selectivity gaps in relay settings tables.

Question 3

Is AI safe to use for arc flash calculations?

Accepted Answer

AI should not perform IEEE 1584-2018 arc flash calculations autonomously — those require validated software (ETAP, SKM, EasyPower). Where AI adds value is in interpreting arc flash study results, generating PPE selection guidance, drafting arc flash label content, and producing NFPA 70E compliance documentation. The engineer of record must verify all arc flash incident energy values and PPE requirements through validated software.

Question 4

How can electrical engineers use AI for RFI and submittal management?

Accepted Answer

AI can draft formal RFI language (referencing specific drawing numbers and spec sections), review submittal packages for completeness against spec requirements, generate commissioning test report templates, and summarize open issues from meeting minutes. Prompt templates tailored to electrical construction workflows dramatically speed up these administrative tasks without requiring engineering judgment.

Question 5

Can AI help with PV and energy storage system sizing?

Accepted Answer

Yes — AI tools can assist with NEC 690.8 string sizing calculations, battery bank capacity calculations (kWh to Ah at nominal voltage), inverter selection criteria, and interconnection agreement checklist generation. Python scripts with pvlib can calculate solar yield and optimal tilt angle. AI also helps interpret utility interconnection requirements and draft the narrative portions of PV design packages.
