You can save time and money by knowing the possible causes of capacitor explosions (you won''t have to replace the blown capacitors as often). So, Why Do Capacitors Explode? An explosion could be caused by a reverse polarity voltage or over-voltage (as little as 1 - 1.5 volts above the voltage can cause an explosion).
Disc capacitors tend to crack open if overloaded-the polarity does not matter. Unless you overvoltage them or reverse voltage them or have a high current ripple in the DC power line beyond the capacitors rating they are safe to use. I have had them (electrolytic can capacitors) explode in my face due to being installed in reverse.

A Definition. As the name implies, a capacitor bank is merely a grouping of several capacitors of the same rating. Capacitor banks may be connected in series or parallel, depending upon the desired rating. As with an individual capacitor, banks of capacitors are used to store electrical energy and condition the flow of that energy.
