J3 Wiring Chart Notes:
1. Power feed wire sizing is based on using 75°C Cu THHN wire with feeder branch
protection rated at 125%.
2. Internal wire sizing is based on using 200°C SEW-2 or PTFE wiring in a raceway
with an ambient temperature up to 60°C.
3. Normal phase-to-phase resistance tolerance is ±5%.
4. 277, 380,415, 480, and 600-volt phase-to-phase resistance values are shown with the
transformer disconnected.
