Sisi in the specifications tells me that it consumes 1500w and that it has a current consumption of 5.6A so I also think that with a 10A outlet it would be fine. What if, my installation does not currently have grounding. It is only protected by a differential and thermal
Are you in a house or apartment? It would be interesting to place a javelin even if it is not for the thermos. In this way and in case of any resistance failure, the leakage will be derived by the javelin and not by the water. The differential will work anyway but when the leak is drifting to ground. When having javelin the differential will act before it is derived to earth for example through a person. It is not that this is going to happen but they are the safety measures that must be taken to avoid accidents. regards
