NEA Standards are guidelines from the National Electrical Manufacturers Association (NEA) for the design and construction of utility poles used to support power lines. These standards outline the material, size, strength and installation requirements for utility poles to ensure that they carry power infrastructure safely and reliably. Poles that meet NEA standards are typically made of wood, steel, or concrete and can withstand a variety of environmental conditions and loads.
