What kind of fuse for a heating mat?

Current flows in electrical installations, which can pose a danger to humans. For this reason, appropriate safeguards are used to minimize such risks. Most often these are overcurrent fuses and residual current circuit breakers. To perform their function, their parameters must be selected for the heating system.

How to check and measure the floor temperature sensor?

The NTC floor temperature sensor, used in electric floor heating, is a vulnerable component. If it is not necessary, do not pull the wired temperature sensor out of the channel (from the floor). First measure its resistance with a meter.
