I'm looking for interpretations of 675.8(B) Main Disconnecting Means.
"The main disconnecting means for the machine shall provide overcurrent protection"

Does a UL98 non-fused switch wired to a fuse block in the control panel comply with this requirement? Or is the only acceptable solution a fusible switch assembly?

Thanks
 
In my opinion you need OCPD for the irrigation machine. The handbook does point out though that if you are withing the 50' range of the motor control panel, the panel switch may act as the disconnect as it probably has overcurrent protection. The question really is what kind of control are you using and in general a bit mroe information about the setup would be helpful in producing a more accurate answer.
 
No doubt that a OCPD is required. My question is regarding what types of OCPD would be acceptable. The industry standard is to use a UL 98 fusible switch.

Would inspectors object to a UL 98 non-fused switch wired to a fuse block in the control panel?

The literal reading is that the disconnect itself must incoprporate OCP; internal fuses do not qualify.

The only answer that matters is the one your inspector has. I recommend asking the inspector.
