why do you add the load short circuit impedance when considering short circuit amperage. It seems that you should only consider supply. If you need to consider loads and you don't know what loads are to be added , what would be a good sub-transient reactance rating for the loads?

hi, in the event earth grounding is not available in a project, is there any other way to make the elcb work? fyi, i have an instant water heater (6.5kw) installed, however if there is grounding in the heating element inside the heater assembly, i will get grounded. thank you in advance to those who will answer my question.
