Rotational Lug Technology, Inc.
Company and Product Description
Rotational Lug Technology (RLT), a privately held company, holds a patent and UL
approvals in the US and Canada on a revolutionary design for a family of lugs used
in the Electrical Switchgear installation business. Currently in development and
leveraging the existing patent are the lugs for the panel board breakers. Over the
years, wires have become larger in size while at the same time switchgear
boxes have become smaller and more compact. Electrical contractors must bend
this large diameter wire in order to land it in the fixed lugs available today by
cable benders and heating beyond the limits allowed by codes and safety.
The design of the rotational lug allows for wire to be seated landed directly, in a
straight line into the switchgear box or breaker. Labor and safety costs are
significantly lower with no need for bending of the wire. Additionally, the setscrews
used to secure the wire no longer require an Allen Wrench, reducing stripping,
loosening and allowing for proper torque to be applied. The combination of
straight-line seating of the wire into the lug, and torque setscrews, significantly
reduces maintenance and overall cost of ownership of the installed switchgear and
breakers.
Benefits
This new technology is revolutionary, in that it benefits all parties
that rely on the current lug applications:
1. The electricians will benefit by use of the lugs because less handling will result
in less injuries.
2. Manufacturers of Switchgears will benefit from the use of the lugs on the bus
through easy, safe and secure installations of wires to switchgears. The
Roto-Lugs fit all standard application busses. By eliminating bending in the wire
and providing a stress-free torque connection to the switchgear, manufacturers will
have confidence that installations meet codes, reducing costly warranty claims and
on-site re-engineering. Further enhancements in the Manufacturers design of
switchgear are no longer limited by the amount of room needed to bend wire in the
cabinet.
3. Wire Manufactures will benefit in much the same way. No longer will wire be bent
beyond allowable radius, reducing heating and insulation stress issues associated
with improper installations. Warranty and compliance claims for wire failures will be
reduced. The lugs have been designed for larger wire diameters, with testing
completed on 750AL-600MCM CU-3/0 in the US and Canada. The lug technology
will provide the same benefits to both larger and smaller wire sizes.
4. Contractors will find significant labor savings in the 50% plus range for switchgear
installations using the Roto-Lugs. Safer, faster and installed according to code will
also reduce on-site work-around, potential warranty disputes, waste wire and rework.
Installations during times of cold temperatures can be completed without having to
bend wires and stressing the insulation.
5. Maintenance contractors and Municipalities will benefit in the same way as installation
contractors. Since the lugs fit on standard busses, replacement of old lugs with the
new design will allow for quick cut-out of old wires and a secure straight-line fit into
the new lug reducing outage times significantly. Properly torque and under no stress
versus the current installation, maintenance costs are significantly reduced. Easy
access to the setscrews will reduce installation time and the special tools required
today.
6. Electrical Engineers, Architects and Zoning Compliance organizations will benefit
from code compliance that today is often overlooked for reason of expediency and
lack of available alternatives. Improperly bent wires, crammed switchgear cabinets
and improper landing, leading to wire and switch failure will be avoided. Inspectors
would have an alternative when coming across improper installations with over bent
wires.
7. Building Owners and the public will be a significant beneficiary resulting from use of
the RLT lugs. By using rotational lugs versus the current fixed lug technology the
total cost of ownership of buildings will be reduced by lower installation costs, less
failure, wire fatigue and lower maintenance.
Other applications:
The rotation lug technology can be applied to many future applications within the electrical
installation industry. The existing patent on the rotational gear and setscrew design can be
applied to breakers, transformers, windmills, and solar as well as other applications.
