The term "blows fuse" refers to an electrical problem where the current flowing through a circuit exceeds its capacity, causing the fuse to blow and break the circuit. Some antonyms for this phrase could be "smooth operation," "consistent flow," or "steady function." When a circuit works smoothly and without any problems, it doesn't blow a fuse. Conversely, when a circuit experiences fluctuations or surges, it can blow a fuse. Therefore, using antonyms for "blows fuse" is an opportunity to describe an electrical system's smooth and reliable operation, which avoids blowing fuses and other malfunctions.
