Based on my work experience of more than ten years! Never press the regulator! Otherwise, a huge coincidence will cause a fire! The best way is to use high-power electrical appliances to pull the power supply! (Leakage protector, short circuit protector) in front! If it is not too much, just install a voltage regulator! Don't take any chances, brother, or you will fly into a rage when you get angry! This is by no means alarmist!
