WHAT IS
MAXIAMP UNDERGROUND?
MAXIAMP Underground is the most technically advanced below grade power feeder system on the market. It is typically used as a primary, secondary or backup power feeder from 1000A to 8000A and 480V to 46kV.
The engineered system combines a MAXIAMP Cable Bus with United Wire & Cable's proprietary, specially designed precast concrete trench with offset vents that enable the power feeder system to achieve free air ampacity rating below grade. Proprietary power venting technology can be used for higher ampacity requirements.
United Wire & Cable has partnered with Trenwa, Inc., the industry leader in precast concrete trench systems as a preferred supplier for our MAXIAMP Underground Cable Bus system.
Achieving free air ampacity rating enables three key advantages for MAXIAMP Underground:
-
It allows us to use smaller and/or fewer cables to deliver the same amount of power - resulting in cost savings.
-
It requires significantly less space underground to install comparative to a typical duct bank installation.
-
It requires less labor to install compared to underground duct bank.
Since mechanical protection is provided by the enclosure, MAXIAMP Underground uses unarmored power conductors that are fully insulated from termination to termination which provides key advantages over other power feeder systems:
-
Power conductors are impervious to moisture and the elements. This provides the safest and most reliable power when compared to bus duct installations which will fail in the event of moisture ingress. MAXIAMP will provide years of reliable services outdoors. In fact, MAXIAMP can even be installed underwater!
-
Unarmored power cables are much easier to install, bend and terminate.
MAXIAMP Underground is
-
Loved by Engineers for its design flexibility
-
Loved by Electricians for its ease of installation
-
Loved by Owners for the years of secure, reliable & safe power provided by MAXIAMP Underground!

System Overview
Cycle through the slides below to learn about the components that comprise the MAXIAMP system
1/7 METAL ENCLOSURE
Special CSA certified multi-level enclosure provided a combination of straight, fixed, and adjustable bend sections consisting of at least 4 I-beams and specially vented top and bottom covers.
Vertical and horizontal bends are available in 90 and 45 degrees.
Stainless Steel enclosure is available for harsh environments.
Still designing and installing Duct Bank?
See why MAXIAMP Underground is the better solution!
Underground Duct Bank
Required cable spacing between cables and multiple circuits demands a significant amount of real estate.
Typical trenching requirements are 16 feet wide (tapered for safety) and 5+ feet deep.
MAXIAMP Underground
The system is incredibly compact and small requiring very little, if any, excavation space.
Typical trenching requirements are 40 inches(!!) wide by 30 inches(!!) deep for the same ampacity requirements.
Underground Duct Bank
The ability to expand or repair the duct system after installation is very difficult, restrictive, disruptive and expensive due to the need for more real estate.
MAXIAMP Underground
MAXIAMP Underground systems feature a trench lid that is removable. This enables a system that is easily accessible and thus simple to expand with additional cables at a later date.
Underground Duct Bank
Pulling cables through bends in conduit introduces risk of excessive pulling tensions, side wall pressure and potential cable tearing action by foreign objects in the duct.
MAXIAMP Underground
When installing a MAXIAMP Underground system the cable can be pulled or laid in place with ease and is always visible during the installation as well as for visual inspections after installation.
Underground Duct Bank
The ducts may shift and/or shear due to ground movement (e.g. frost heave), damaging the cables.
In fact, a local utility representative informed us that they typically have 3 duct bank failures - every year!!!
MAXIAMP Underground
Concrete encasement and I-beam enclosure design of MAXIAMP Underground effectively protects the cables during ground movement.
MAXIAMP Underground has a perfect track record with ZERO failures!
