Dummy you should have read before posting your angry reply. Here people want to install a stabilizer to protect their ac from voltage fluctuations. And I am recommending them to install voltage breaker. A voltage fluctuation happens when a crap transformer is installed by wapda to burn your appliances with abrupt voltage spikes and dead low voltages that even stabilizer can not accept and simply stop giving output.
These stabilizers are only useful when you have constant low voltage problem due to overloaded transformer of your area and you are getting low voltages like 170 - 180 v constant. Then stabilizer is quite useful
Clearly this hot weather has fucked up brains of people. 🤦♂️
