About Photovoltaic panel wiring safety precautions
Just as with other electric power generation, PV systems present the risk of shock and electrocution when current takes an unintended path through a human body. Current as low as 75 milliamps (mA) across the heart is lethal. The human body has a resistance of about 600 ohms. Per Ohm’s law,voltage (V) equals current.
As with any electrical system, fire is always a potential hazard. Perhaps one of the most common causes is electrical arc faults,which are high power discharges of electricity between two or.
Large-scale PV arrays with medium and high levels of voltage are susceptible to arc flash. This is especially true when a technician is checking for faults in energized combiner boxes where PV source circuits are.
