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 inform
ation on 277V, 415V, or 440V m
odels 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 transform
e
r
disconnected.
6. For 575V m
odels, multiply the kW rating of the 600V m
odel by a de-rating factor of 0.92
to get the actual rating for 575V.
7. For m
odels 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 diagram
