Photovoltaic combiner box DC circuit breaker

How do you disconnect a PV combiner box?

Ensure the circuit breaker is in the “OFF” or “TRIP” position (or the load isolation switch is in the “OFF” position) to disconnect the combiner box from the PV DC output side. All fuse holders inside the combiner box should be open (or remove the fuse core using specialized pliers) to disconnect the DC combiner box from the PV string input side.

What is a photovoltaic DC combiner box?
