Welcome to Mercury’s Electrical Division. Our electrical services center around providing products, repair, and installation for the communications industry. We specialize in ultra clean, low cost, and backup reliable electrical power, for data centers, labs, server rooms, and many other critical areas.

During the late 70’s Mercury’s Security division acquired our knowledge and experience in security systems by working on Nuclear Power plants around the country. Many of the products we use today came from our designs for the demanding needs of this industry. We pride ourselves on providing only top quality, fully tested, and proven products along with experienced and licensed technicians.

In 1978, Mercury’s Voice and Data Cabling division installed the first IBM local area network in CT. Since then, we have installed hundreds of networks and many miles of cabling. We service all of CT. When requested, we will go anywhere in the US. There is no project too small or too large. Each project gets the attention and design needed for years of care-free operation.


“The difficult we do immediately-

the impossible takes a little longer.”

At The Mercury Group, we simply believe in getting a job done right – no matter the size!
