circuit breaker
n.— «I do qualify for the circuit breaker—or as I call it, rent refund program. This state program provides refunds to primarily property taxpayers, if their taxes exceed a certain percentage of income; however, the other part of the program provides relief to renters and there are more and more of us every day.» —“Easy money for most seniors” by Kay Soldier keepMEcurrent.com (Westbrook, Maine) Sept. 14, 2006.
