A Safer & More Economical Lighting System
4th Edition 2001 Standard Specifications for Structural Supports for Highway Signs, Luminaires and Traffic Signals Published by the American Association of State Highway and Transportation Officials Please be advised that AASHTO has published the new 2001 Standard Specifications for Structural Supports for Highway Signs, Luminaires and Traffic Signals.
The Field Proven Wiring System within the Many Departments of Transportation Since Additional Requirements shall Efforts shall be made in all breakaway supports housing electrical Components to effectively reduce fire and electrical hazards posed after structure impact by an errant vehicle. Upon knockdown, shall the support/ structure shall electrically disconnect as close to the concrete foundation (pole base) as possible.C)
Upon knockdown, the structure shall electrically disconnect as close to the concrete foundation (pole base) as possible. The new specification can be summed up by the sentence, Upon knockdown, the structure shall electrically disconnect as close to the concrete foundation (pole base) as possible. A review of your states current knockdowns as compared to knockdowns where the [MG]² DOT PLUG breakaway wiring system has been utilized is needed to determine whether or not your states current specification adheres to the AASHTO standard specification. The DOT PLUG system can assure your compliance with AASHTO and reduce if not eliminate future liability in the event of injury or death attributed to electrical wiring of a breakaway structure. An assessment of most states has shown their current wiring method or system would not comply with the new criteria. We at [MG]² have a library of photographs depicting knockdowns across the country and would be happy to share same with you. DOT PLUG has been used across the country and in Canada since 1992 to provide the safest and easiest to maintain electrical disconnect in the industry. The DOT PLUG system is the only such system available with a 20-year warranty. We would welcome the opportunity to meet with you and your staff to discuss whether your state is currently compliant with AASHTO, and if not, what we can do to assist you in insuring the safety of the users of your state and municipal highways.
What Is On The Roadway Now?
Why Change? The Physics of a Knockdown Dictate the Need for an AASHTO Compliant Disconnect Device
Knockdown Remains Using Old Wiring Method
More Knockdowns Using Old Wiring Method
What Can Happen with the Old Wiring System?
Eliminated DOT PLUG ® Hazards & Problems of Old Wiring Method & Systems that are Eliminated with the: DOT PLUG ® Cable System Possible electrocution to accident victims, rescue personnel, pedestrians and law enforcement officials. Possible fire following accident due to sparking wires. Proper pole trajection on disconnect prevented. Delayed rescue efforts due to exposed wire. Lawsuit against DOT, design & consulting engineer or contractor due to injury or death from a preventable fire or electrocution during accident. Easy accessibility to expensive solid copper wire for cable thieves.
Eliminated DOT PLUG ® Hazards & Problems of Old Wiring Method & Systems that are Eliminated with the: DOT PLUG ® Cable System Damaged splices in adjoining poles. Requirement of securing site prior to installation of new pole Wire repair or replacement / Fuse and Fuseholder replacement / Surge Arrester replacement Resplicing all connections after every knockdown Damage to wire or pole from highway mowers One knockdown taking out entire light run which is fed on same circuit

DOT PLUG ® DOT PLUG ® Is The Safest & Most Efficient Breakaway Wiring System Available Subsequent Fire or Electrocution Eliminated DOT/Specifier Liability Reduced or Eliminated Site Safe & Secure at Moment of Knockdown Time to Rewire & Restand Pole Greatly Reduced
No Maintenance Inside Pole!
DOT PLUG ® The DOT PLUG ® Wiring System has Gained National and International Acceptance as a Safer & More Efficient Wiring System Discussed in Detail in FHWA Publication # FHWA-HI Wiring Method Taught in National Highway Institute Course #38034 Design, Construction & Maintenance of Highway Safety Features & Appurtenances Discussed in Detail in McGraw-Hills Highway Engineering Handbook ISBN# DOT PLUG ® Utilized in Alabama, Arizona, Florida, Georgia, Louisiana, Minnesota, North Carolina, Oklahoma, South Carolina, Tennessee, Washington, and Canada
