Thinking about building a new grain bin? Before you start planning, contact Pella Cooperative Electric and we’ll help you with your plans to ensure compliance with Iowa State Code.
PCEA will provide assistance in planning for a safe environment for everyone working and living around grain bins. The State of Iowa requires specific clearances for electric lines around grain bins, with different standards for those filled by portable and permanent augers, conveyors, and elevators, as well as permanent equipment.
Electric wires should be at least 15 feet from the non-loading side of the grain bin; at least 18 feet from the highest filling or probing port on the bin; and a clearance of at least the bin height plus 18 feet from the loading side of the grain bin. Electric service cannot be provided to a grain bin installation that does not meet these clearances.
According to the Iowa Electric Safety Code found in Iowa Administrative Code Chapter 199 – 25.2(3)b. An electric utility may refuse to provide electric service to any grain bin built near an existing electric line which does not provide the clearances required by the American National Standards Institute (ANSI) C2-2017 “National Electric Safety Code,” Rule 234F. This paragraph “b” shall apply only to grain bins loaded by portable augers, conveyors or elevators and built after September 9, 1992, or to grain bins loaded by permanently installed augers, conveyors, or elevator systems installed after December 24, 1997. (As adopted by the Iowa Utilities Board).
If the electric wires around your existing or proposed grain bin do not meet the requirements shown in the diagrams, or if you have any questions, please contact our office at 515-628-1040.
