⚠️ Curated reference — the Philippine Electrical Code (PEC) is based on the U.S. National Electrical Code; the values here are the widely-taught standard figures. Always verify against the official PEC edition your course/board uses and your professor's notes before using them in a design or exam answer. Ampacity, correction-factor and demand tables vary by edition and installation.
