J6 and J16 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. For information on 277V, 415V, or 440V models reference the supplied drawing
or contact the factory.
4. Normal phase-to-phase resistance tolerance is ±5%.
5. 380, 480, and 600-volt phase-to-phase resistance values are shown with the transformer
disconnected.
6. For 575V models, m
ultiply the kW rating of the 600V model by a de-rating factor of 0.92
to get the actual rating for 575V.
7. For models manufactured prior to June 24, 2005, that utilize wiring diagrams 3, 5, 6,
7(NT), 7(WT), or 11 please contact the factory for wiring diagrams.
