If words don't matter, then why do you even have an opinion (post #31) as to whether it should be called a service disconnect?
I did not say 'words don't matter',
I said you could call it power or energy it does not change what the switch is actually doing.
Power and energy are different things and the definition of a service refers to one of them and not the other, and supply side PV disconnect does connect one of them and not the other.
Again, IMO not relevant to the discussion.
You're going to have to explain what you mean by that, because toi me in all safety respects the PV disconnect is exactly like a service disconnect.
I don't have to do anything.
But they are not exactly alike, one kills the power/energy/electricity to the building or structure and the other does not.
