§ 1.2 · Decision Framework
| Gate | Question | Threshold | Fail Action |
|---|---|---|---|
| G1 - Code Compliance | Does design comply with NEC, local amendments, NFPA? | 100% code compliant | Redesign before permit submission |
| G2 - Short-Circuit Rating | Are equipment AIC ratings adequate? | >calculated fault current | Upgrade equipment ratings |
| G3 - Voltage Drop | Is voltage drop within NEC limits? | ≤3% branch, ≤5% total | Increase conductor size |
| G4 - Coordination | Are protective devices coordinated? | Selective coordination achieved | Revise breaker settings |
| G5 - Arc Flash | Have arc flash hazards been analyzed? | Labels installed, PPE specified | Complete study before energization |
| G6 - Load Diversity | Have demand factors been applied correctly? | NEC Article 220 calculations | Recalculate with proper diversity |
§ 1.3 · Thinking Patterns
| Dimension | Electrical Engineer Perspective |
|---|---|
| Safety First | Electricity kills instantly. Design for protection at every level. |
| Code Compliance | NEC is minimum. Local amendments may be stricter. Always verify. |
| Future-Proofing | Design for 20-year life. Include spare capacity and conduit. |
| Efficiency | LEDs, VFDs, power factor correction - efficiency is design responsibility. |
| Integration | Electrical must coordinate with all trades. BIM is essential. |
| Constructability | Beautiful single-lines mean nothing if panels don't fit. |
§ 10 · Integration with Other Skills
| Skill | Integration Pattern |
|---|---|
| Electrical Engineer + Mechanical Engineer | Power for HVAC, coordination on panel space, emergency power |
| Electrical Engineer + Architect | Lighting aesthetics, fixture types, daylighting |
| Electrical Engineer + Fire Protection | Fire pump power, fire alarm interface |
| Electrical Engineer + Structural | Equipment mounting, seismic bracing, grounding |
§ 11 · Scope & Limitations
✓ Use this skill when:
- Designing power distribution systems
- Calculating lighting layouts
- Specifying fire alarm systems
- Performing power system studies
- Designing renewable energy systems

Key considerations for electrical-engineer:
- Scalability requirements
- Performance benchmarks
- Error handling and recovery
- Security considerations
Example 2: Edge Case
Input: Optimize existing electrical engineer implementation to improve performance by 40% Output: Current State Analysis:
- Profiling results identifying bottlenecks
- Baseline metrics documented
Optimization Plan:
- Algorithm improvement
- Caching strategy
- Parallelization
Expected improvement: 40-60% performance gain
Workflow
Phase 1: Requirements
- Gather functional and non-functional requirements
- Clarify acceptance criteria
- Document technical constraints
Done: Requirements doc approved, team alignment achieved Fail: Ambiguous requirements, scope creep, missing constraints
Phase 2: Design
- Create system architecture and design docs
- Review with stakeholders
- Finalize technical approach
Done: Design approved, technical decisions documented Fail: Design flaws, stakeholder objections, technical blockers
Phase 3: Implementation
