Q: Are MCBs OK for DC?
A: When working with DC circuits, it is crucial to use MCBs that are specifically designed and marked with DC ratings. It is important to note that AC MCBs should never be used in DC circuits, as they are not designed to extinguish the arc that is created in DC circuits. Using AC MCBs in DC circuits can lead to overheating of wires, which can ultimately result in a fire. Therefore, it is not safe to assume that AC MCBs can be used in DC circuits solely based on their matching ampere and voltage ratings.
Q: What does a PV disconnect switch do?
A: The PV disconnect switch acts as a breaker that breaks the DC current flow from the solar panels to the inverter, and the AC Disconnect switch separates the inverter from the electrical grid.
Q: What is a solar combiner box used for?
A: Solar panel combiner boxes, also known as solar photovoltaic array combiners, play a crucial role in combining multiple solar panels or strings of panels into a unified bus. These junction boxes are specifically designed to handle the wiring used in PV systems.
