FAQ
LED reduces this? +
For service sizing, no — code uses occupancy-based minimums. For actual energy use, yes — LEDs draw 80% less than incandescent.
Why dwelling 3 VA/sf? +
It is a minimum number for service planning, not actual installed wattage. Most modern homes draw less but you size for code.
