Maintain Proper Clearance Around Grain Bins
 Grain Bin clearance

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.
