The heating wire is generally only a few tens of ohm resistance, and it is measured at the 200 position of the resistance gear to see if there is resistance.
There are errors, and the resistance value measured with a multimeter is not accurate at all, only a rough measurement, as long as the measurement is not broken, it is good! >>>More
There is a short circuit between the two lines.
The two wires can be used as one, and the ground wire can be used as the zero line temporarily. >>>More
There is no problem at all, the smart toilet 220-250 can be used.
The low line voltage in the kitchen is due to other loads being skewed into the wiring. If the contact is corroded, it becomes a resistor invisibly. The grid voltage passes through this resistance to form a certain voltage drop. >>>More
Check the voltage of the live wire to the neutral line and the voltage of the live wire to the ground wire. >>>More
