    "notes": "Standard breakers must not be loaded past 80% of their rating by a continuous load (3+ hours) — equivalent to sizing the breaker at 1.25x the continuous current, per NEC 210.19(A)(1)/210.20(A).\nThis sizes the breaker's ampere rating only. Conductor sizing, terminal temperature ratings and voltage drop must be checked separately against NEC Table 310.16 (or your local code) before wiring a circuit.\nThis is a rule-of-thumb estimate, not a substitute for a licensed electrician's review — especially for a permanent installation."
