The Electrical Board of Missouri and Illinois manages an Electrical Expo that attracts manufacturers from across the country. The Expo is held every three years and this year will be held at the St. Charles Convention Center.

Attendees can take advantage of seeing thousands of products used in the electrical construction industry all in one place.

In addition to product information, seminars are held on a wide variety of topics to enhance the educational value of the Expo. One of the most popular seminars is an update on the National Electrical Code which attracts over 500 participants. This seminar is presented in cooperation with the International Association of Electrical Inspectors - St. Louis Chapter.
