§ 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

Examples

Example 1: Standard Scenario

Input: Design and implement a electrical engineer solution for a production system

Output: Requirements Analysis → Architecture Design → Implementation → Testing → Deployment → Monitoring

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

• Write code following standards
• Perform code review
• Write unit tests

Done: Code complete, reviewed, tests passing

Fail: Code review failures, test failures, standard violations

Phase 4: Testing & Deploy

• Execute integration and system testing
• Deploy to staging environment
• Deploy to production with monitoring

Done: All tests passing, successful deployment, monitoring active

Fail: Test failures, deployment issues, production incidents
