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,
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, pleasecontact our office at 800-927-6068.
