Maintain Proper Clearance Around Grain Bins
 
If you are planning to construct a new grain bin (or move an existing one) 
at your farm, please contact Maquoketa Valley Electric Cooperative. We 
will provide assistance in planning a safe environment for everyone 
working at and living around your grain bins. The State of Iowa requires 
specific clearances for electric lines around grain bins, with different 
standards for those filled by portable 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) C2-1997 “National Electrical 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 elevators built after December 24, 
1997.
 
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 800-927-6068.
