Other major end markets include building systems, electrical infrastructure, industrial systems, lighting systems and utility systems. Their combined industries account for 360,000 American jobs in more than 7,000 facilities in every state. Their industry produces $106 billion shipments of electrical equipment and medical imaging technologies per year with $36 billion exports. NEMA also has offices in Mexico City.
