Many existing swine buildings have been wired using practices and materials that cannot withstand these conditions. Ammonia, hydrogen sulfide, and other corrosive gases, in combination with moisture and dust, hasten deterioration of electrical components. Open and enclosed swine housing structures and other buildings that are washed periodically should be considered damp and corrosive atmospheres. However, most small feed-grain handling centers are not classified as areas requiring dust-ignition-proof wiring and should be wired like swine structures described below. Dust-ignition-proof wiring systems should be used in extremely dusty feed processing areas. These buildings may normally be wired with the same materials commonly used in residences and in accordance with standard procedures and practices of the NEC. Such structures include garages (detached from houses), machine sheds, shops, and similar buildings. Check with your insurance company before beginning construction to determine insurance requirements.Дry farm buildings generally do not require special wiring materials or procedures. Some companies will not insure buildings wired by older commonly used methods. Assistance is often available from your power supplier in planning and installing the distribution system to your building. For these, consult with a qualified electrician having training, experience, and knowledge of the National Electrical CodeВ® (NEC) and proper wiring practices.

This leaflet does not provide sufficient information to properly design and install an electrical wiring system, nor does it describe all specialty devices, mechanical protection, and special requirements for feed handling and grain storage facilities with severe dust problems. The lowest priced electrical system is seldom the most economical. Because of the potential impact a fire loss can have on the total swine enterprise, all wiring should meet or exceed the minimum standard. Good practices often go beyond the bare minimum of the NEC to minimize fire hazards and reduce future maintenance problems. Nevertheless, the NEC provides a standard (Article 547) for wiring swine buildings or other damp corrosive environments. In other states, agricultural structures are exempted from national, state, or local codes, so NEC practices often are not followed.

The NEC has become law in many states, but often there is limited inspection or enforcement in rural areas. The NEC is a guide to selection and safe installation of proper materials. The standard for electrical work in the United States is the National Electrical CodeВ® (NEC) published by the National Fire Protection Association.

Educate the producer to advise the electrician on how the building should be wired to allow maximum production efficiency and safety.

Identify potential wiring problems in current and new swine buildings.

Introduce basic electrical equipment and wiring techniques used in swine facilities.

Special wiring methods and components are needed for swine structures. The mere fact that a system вЂњworksвЂќ doesnвЂ™t speak for its safety. Even when fires do not occur, poor wiring may contribute to higher maintenance costs. Inferior wiring causes hazardous conditions for livestock and humans, expense of early rewiring of many buildings, and possible fires. Many wiring practices that are acceptable for use in our homes are unsafe when used in livestock housing because of exposure to dust, moisture, corrosive gases, and physical damage. A majority of all farm fire losses are related to electrical system failure (Figure 1). Proper design and installation of swine facility electrical systems are crucial to using electricity efficiently, providing safety for workers and animals, and minimizing potential fire loss.
