A Safer & More Economical Lighting System
 

The Safest and easiest-to-maintain wiring system for roadway poles, the DOT·PLUG™ Break-Away Cable System is the preferred system for safety, durability and less "down-time"; plus DOT·PLUG™   is AASHTO compliant.

The Hazards of Conventional Wiring

Decades ago safety and roadway engineers realized that lighting poles needed to be redesigned to "break-away" from their foundation to prevent deadly accidents caused when a motorist runs off the road and strikes a light pole.  The "break-away" design is now standard for lighting poles inside the "clear zone" and has saved many lives, but one detail that was overlooked was the electrical wiring or "conventional wiring" inside the "break-away" poles. 

Conventional wiring poses a high threat and has caused many injuries and fatalities nationwide due to improper pole trajectory, and the electrical and fire hazard caused from exposed wires and sheered off fuses.

Safer and more Economical DOT•PLUG

[MG]˛, Inc. debuted the first "break-away" wiring system in 1992.  This revolutionized the industry to a new way of thinking by creating a crush proof, flame retardant, IP-68 rated submergible system that placed the fuses below grade, with a simple cord system that "unplugs" during a knock down. 

Designed after the cord systems used on our military submarines and aircraft carriers, the DOT•PLUG system also allows for ease of maintenance of fuses and surge arrestors, along with submergible and re-enterable splices allows most pole knockdowns a reusable system.

THE DOT•PLUG SYSTEM™ is suitable for many different voltage systems. It is normally shipped with 2 of the 3 conductors fused and the un-used conductor being generally used as the Grounding conductor.

Should a Voltage System be determined by the contractor not to require but one fused conductor, the installed fuse in one of the fused conductors may be replaced by a slug.
