Photovoltaic combiner box negative pole current

Can I use the same fuse for positive and negative poles? While possible, we recommend polarity-specific fuses due to different thermal profiles and fault current paths. How often should combiner box fuses be replaced?. What is the advantage/disadvantage of protecting the negative end of the circuit with a breaker? If I can do it, you can do it. But there are codes for the PV circuits. OCP (fuse or breaker) is required. . Each combiner box has 20 strings connected to it. Let's say I have 10 combiner boxes that are connected to an inverter, and while the inverter is running I see 3 combiner boxes recording negative current while the 7 of them are recording positive current, and there is no ground fault on the. . ance cables by combining strings at the array locat ciency, reliability and safety in solar energy systems.
