At the same time, increased wire size is insurance against future changing needs and assures lower voltage drops. Copper upsizing also minimizes costly operations problems, particularly downtime due to overheated or failed equipment. Reliability and service life of electrical equipment are substantially increased. Even if you pay a lower premium for electronic ballasts, you may still wait up to 6 years for a return on your investment. Install electrical equipment that contains more copper.
Copper runs cooler and saves energy and money.
The more copper your electrical equipment windings and cabling contain the less costly energy you'll lose as heat because copper is the most efficient conductor available. The law of physics says that all electrical equipment wastes energy in the form of heat. Sit down with your plant engineer or facilities manager. Compare the costs and compare the savings. You will find that energy efficient electrical equipment and cabling put the I R law on your side.
