Hi Terry and Bart,

My interpretation of the picture is that all twelve caps are wired in 
series as oppose to two strings of 6.  If this is correct, my only 
concern is the two caps on the same end would be separated by only 
the PVC and would have the full NST peak voltage between them.  Seems 
like the a 15KV NST can arc across a 1 inch distance.  Many wire 
their caps serpentine fashion (zig zag) so the NST voltage is applied 
across the opposite ends of the string.
