Editorial Standards & Technical Review Board
Peer-reviewed conductor sizing calculations, ampacity adjustments, and electrical code compliance guides governed strictly by NFPA 70 (NEC), IEEE, and ABYC standards.
Engineering Integrity & Safety Mandate
Electrical installations carry life-safety, fire-prevention, and operational liabilities governed by the National Electrical Code (NEC) and marine/industrial safety bodies. WireSizerPro operates under an engineering-first editorial process. Every formula, calculator engine, and installation guide is produced or audited by credentialed industry professionals—combining licensed Professional Engineers (PE), Master Electricians, and certified marine technicians.
How We Verify Electrical Guidance
- Rigorous Mathematical Modeling: Voltage drop algorithms rely on precise circular mil resistivity formulas rather than rough rule-of-thumb approximations.
- Thermal & Terminal Derating Limits: Sizing evaluations enforce NEC 110.14(C) terminal temperature limits (60°C vs. 75°C vs. 90°C) and continuous duty factors (125% rule).
- Active Code-Cycle Re-Audits: Reference tables and calculators are updated proactively as new NFPA 70 code editions and ABYC revisions are adopted.
The Engineering Review Board
Elena Vance, PE
Lead Electrical Systems Engineer • Licensed Master ElectricianElena oversees the core wire sizing calculations and code verification across WireSizerPro. With 16+ years of field engineering and installation experience, she specializes in continuous load calculations (NEC 625 & 210), EV charging infrastructure, and circular mil voltage drop derivations.
David Sterling, PE
Senior Power Systems Engineer • Industrial Code ConsultantWith 18 years in industrial substation design and commercial power distribution, David audits WireSizerPro’s 480V/208V 3-phase calculation engines, transformer secondary feeder sizing, and NEC Chapter 9 conduit fill algorithms.
Capt. Sarah Jenkins
ABYC Master Marine Electrician • USCG Master CaptainCapt. Sarah brings 14 years of maritime and off-grid electrical experience. Certified under ABYC E-11, she evaluates low-voltage DC ampacity, marine battery bank interconnects, and rooftop-to-MPPT solar string wire sizing.
Marcus Thorne, PE
Senior Thermal & Infrastructure Engineer • ASHRAE MemberMarcus focuses on thermal derating dynamics, attic ambient heat corrections, and HVAC circuit safety. He audits WireSizerPro’s heat pump wire sizing guides and Minimum Circuit Ampacity (MCA) vs. Maximum Overcurrent Protection (MOP) calculations[cite: 1, 2].
Dr. Julian Mercer
Principal Hardware Systems Architect • IPC CID+Dr. Mercer leads the technical standards for low-voltage electronic design and trace ampacity. With a Ph.D. in Computer Engineering, he validates WireSizerPro’s IPC-2152 trace width algorithms, internal/external copper plane heat dissipation, and chassis DC wiring models[cite: 2, 8].
