Note: Use NEC code max column for low to moderate reverse/jog/

plug applications.

* Heavy Start permitted only if NEC code max does not allow motor start-up.

**If equipment terminations are rated for 60°C conductors only, the 60°C

conductor ampacities must be utilized and therefore larger conductor sizes or

conduit sizes may be required.
