TMS swaps out circuit breakers in lighting system

FORT WORTH, Texas — Texas Motor Speedway changed out all the circuit breakers in its lighting system prior to Saturday night’s Sprint Cup race at the facility to avoid localized outages like those that briefly interrupted the track’s Nationwide Series event.
Friday night’s Nationwide race was stopped under a red flag for a little less than six minutes as track technicians changed out a circuit breaker that had tripped and knocked out some of the lights in Turn 3. It was the second failure of the same circuit breaker that evening, which track president Eddie Gossage attributed to the piece of equipment being 15 years old.
As a precaution, Gossage said track maintenance workers changed out all 400 breakers overnight Saturday. The track had extras stored in a warehouse on the property.
“They simply went though and changed the breakers, putting new ones in, because they’re 15 years old,” Gossage said Saturday. “Just to be sure.”
Sure hope there is no more of that nonsense tonight!
