Why we do what we do: In the world today electrical systems are at the heart of every operation and every industry. Without that power, and the proper control of that power, office buildings cannot power the lights and computers that transact business and manufacturing facilities cannot operate the machines that produce their goods. In short, the modern world comes to a halt. IER exists to ensure that the equipment for your world is configured the way you want it and available in the time frame you need it so your world can continue to operate. IER Has grown into a UL approved OEM shop known for our "can and will do" attitude and emergency quick ship responses. We are not an online store, we house and keep on hand inventory to make it possible to build your equipment exactly to your specifications and get it out to you within 24 hours in most cases. We have over 50 years of combined experience in the electrical field to assist in making sure you have everything you need. Don’t compromise, we don’t!
