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.
