The panels at Mercer Controls are designed by S. A. Mercer, P.E., whose years of experience in both electrical controls and utility construction management combine to offer a wealth of knowledge to assist our customers in any applications they may have. No matter the size of the job, his relative insight and experience have enabled development of quality standards for design, component choices, assembly, and functional reliability that insure a high level of customer satisfaction. His team of employees have been well versed to conform to these essential quality guidelines and they take pride in the fact that their work is recognized as such.
