§ 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

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:

1. Algorithm improvement
2. Caching strategy
3. 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

Domain Benchmarks

Metric	Industry Standard	Target
