ok, sorry for trying to learn

so it can't have a faulty line wire inside that could energize the frame?? can you tell us a device which metal frame can be energized by a faulty wire?

ok berkeman thank you for explain us that the washing machine was a bad example. A toaster 'live' frame would be ok in order to go back to the main point of the question.. in which case the person is getting an electric shock?

double-fault? can you explain us what is that? only the washing machine has its frame energized in all the cases shown, as can be seen in the diagrams

thanks, I added it

Hello, let's say the AC generator and the washing machine, with a live metal frame due to a fault, are floating-neutral and floating-ground. These are many combinations where both get and get not bonded/grounded. Can anybody tell us in which case the person gets an electric shock when touches...

The steady state current that the NTC will have, will be a maximum of 5A AC (the charger and maybe a couple of notebooks now I'm thinking). The generator is this https://koenner-soehnen.com/en/inverter-generator-ks-2100ig-s I don't have a datasheet, just the technical parameters of the website

Thanks for the info ;) Sure, this is the datasheet of the battery charger https://files.gwl.eu/inc/_doc/attach/StoItem/8257/Datasheet_MW-NPB-750-12.pdf

Well, the whole point is not to exceed the maximum power of the generator. I don't have the generator yet but I don't want to blow its fuse. I only have its specs and they say what I posted first.. AC current (steady) 4A and inrush current 50A. The generator will be loaded with the charger and...

Hi, as I understand, generators are rated for nominal power and maximum power.. the first for steady values and the latter for maximum peak values such as inrush currents. Any value over the max power hurts the generator.. correct me if I'm wrong. I've seen NFC thermistors such as this...

Hello, I have an AC-DC power charger that has a inrush current of 50A at 230V and I need to reduce it to a maximum of 7.82A at 230V to use it with a certain power generator. What NTC thermistor or circuit do you recommend me to put between the charger and the generator, in order to protect the...
