In many cases, a wiring box is attached to a PV inverter(residental use).

Generally, The wiring box has a DC circuit breaker and has an AC breaker or communication circuit as an option.
I heard that the wiring box is mandatory  in the United States.(Not correct....)
So, I am wondering if a wiring box is necessary when selling PV inverter(residental use - small size) in the United States. If not, I wonder why so many manufacturers make a wiring boxes.
