I Have Received A Request To Install Eleven 480 Volt 100 Amp Cord Caps Exiting 24 Inches Out The Bottom Of A Wireway Mounted 12 Ft A.f.f.. Will The Branch Breakers Located With In 50 Ft Serve As A Suitable Disconnecting Means, Or Should I Install A Combination Service Disconnect/pin And Sleeve Receptacle, That Does Not Allow Un Plugging Untill The Disconnect Has Been Turned Off? Thanks.
