What are the interrupting ratings for pump panels?

Pump panels with fusible disconnect:  suitable for use on a circuit capable of delivering not more than 100,000 rms symmetrical amperes.  600V max where a Class R fuse clip is installed and Class R fuses are used.  If Class R fuses are not used, the switch should not be installed on circuits capable of delivering more than 10,000 rms symmetrical amperes.  Size 6 is limited to 18,000 and Size 7 is limited to 30,000 rms symmetrical amperes.  Pump panels with circuit breakers:  sizes 1–3 are suitable for use on circuits capable of delivering not more than 100,000 rms symmetrical amperes at 480V maximum; for 600V applications not more than 65,000 rms symmetrical amperes.  Irrigation pump panels (ECP):  suitable for use on circuits capable of delivering not more than 10,000 rms symmetrical amperes at 480V max.
