6 FAQs about [Photovoltaic combiner box electric shock accident case]

Can a PV installation cause a shock accident?

Anytime a PV installation consists of more than two PV modules, a shock accident should be presumed to exist. The best possible method to avoid electric shock is to measure-always measure- the voltage from any conductor to any other conductor, and to ground. Use a clamp-on ammeter to measure and record the current flowing in the conductors.

What causes electrical shocks in a PV system?

Electrical shocks are typically caused by a short circuit resulting from corroded cables and connections, loose wiring, and improper grounding. Key places to look for these conditions in a PV system include the combiner box, PV source and output circuit conductors, and the equipment grounding conductor.

Are photovoltaic systems a fire hazard?

In recent years, it is evident that there is a surge in photovoltaic (PV) systems installations on buildings. It is concerning that PV system related fire incidents have been reported throughout the years. Like any other electrical power system, PV systems pose fire and electrical hazards when at fault.

Can a PV system cause a DC arc flash?

During the course of fire on a building with a PV system, DC cable insulation can melt and cause a DC arc flash. The same may occur if a PV system is disconnected incorrectly. DC arcs are not only an additional life safety threat to firefighters, but also an ignition source, which will be discussed later in more detail.

What are the requirements for exempting electrical shock in a PV system?

For PV systems of a 1000 voltage DC source, Underwriters Laboratories recommends the mandatory characteristics of water application in exempting electrical shock are as follows: (a) a minimum 10-degree fog pattern of the cone shape, (b) saltwater use is prohibited, and (c) a distance of minimum 20 feet (6 m) from energized source (1).

What causes arcs in a PV system?

In a PV system, arcs may be caused by loose terminals, poor contact, broken cables, aging, carbonized, or damaged insulation materials, or damp and corrosive wires. Electric arcs are likely to occur as there are many wiring terminals on the DC side of the PV system. Figure 1-4 shows the types of arcs that may be generated in a PV array.
