You should also add a series 200 Ohm, 200 Watt resistor in series with a 2" 
ID PVC tubing inductor (air core) wound approx 16 inches long with #24 PVC 
insulated wire.  This will clip any incoming transients from the quick 
connect / disconnect of the power supply and the cap bank.  Mount this array 
on an insulating material such as PE, PS, etc.
