Section 5. Structures and Utilities
Electricity Disruptions Continued
|There are several types of generators:
Whether it's a direct-connected engine-driven unit or one driven by a tractor power take-off (PTO), be sure a double-pole, double-throw transfer switch is properly installed by a licensed electrician if the generator is to be connected directly to the farm wiring. This switch disconnects the commercial electricity supplier power source (the electric power company lines) from the farm electrical wiring and prevents electricity made by the generator from flowing onto utility lines where it could electrocute members of the repair crew. The switch must have the capacity to carry the total load of the farm or building it feeds, even though the generator has less capacity. When the switch is in its second position, the generator is separately connected to only the farm’s (or building) electrical wiring. Extension cords typically connect individual equipment (freezers, portable lights) to small generators.
