>From my cryptic notes the Array Solutions box used:
10000 pF / 1KV capacitor
82V Varistor 6.5KA
Cost ~$1.00 for the capacitor and varistor from Digikey or Mouser.

John,
>From the photos, each lead has an MOV and capacitor in parallel shunted to
ground. The Array Solutions boxes are really nice and convenient, but in a
few hours I could fabricate that with a grounding buss bar, NEMA box and
some stainless hardware.
What values would you recommend for the MOV and capacitor?
