A car accident might have been the cause of a partial DeKalb blackout Monday night which left an estimated 300 homes without power.

Although Commonwealth Edison officials are unsure of the blackout’s exact cause, they estimated “the problem was caused by some sort of deviation or accident at 10th and Taylor (streets),” a Com Ed spokesman said. Power outages were reported at about 9 p.m.

“It sounds like a car had gone south on 10th Street and hit a pole at Taylor. This guy wire flipped up into the air and into a 34,000 volt wire,” he added. No further details were available at press time.

A guy wire is under tremendous tension and serves to support a pole which holds up power lines. The 34,000 volt wire did not pose any danger because it grounded itself out, which the spokesman compared to blowing a household fuse.

DeKalb police and fire departments worked to set up stop signs at several blacked-out intersections.

Aside from the estimated 300 homes which were without power, major electricity consumers without service were Spaulding Composites, 1300 S. 7th St., A. O. Smith Harvestore Products Inc., 345 Harvestore Drive and a 12,000 volt electrical feeder, the spokesman said. These consumers were without power for about seven to 19 minutes.
