There are several causes for the trip of the leakage protector:
1. The cross-sectional area of the electric heater power wire is not enough, causing the power wire to overheat and causing the leakage protector to misoperate. You can check the power cable or replace the power cable that matches the heating element's power.
2. Quality problems of the leakage protector, you can replace the leakage protector and have a try.
3. When the electic heater working, there may be moisture in the magnesium oxide powder inside it, resulting in short circuit leakage. You can check the installation environment around it.
4.The wiring method is wrong, resulting in the electric heater's surface load is too large to burn it.
5.The quality problem of the electric heater element itself , you can change it and have a try.
