Just want to check my thinking here. Depending on how a service is configured, the same size service may have a different size gec per 250.66.

Example: 400 amp service, one service disconnect, 500kcmil, = 1/0cu gec per 250.66.

(2)200 amp disconnects, 3/0 - 167800kcmil x 2 = 335600. 350kcmil = #2cu gec per 250.66

Thanks, Buck

Dillon3c tends to write in incomplete sentences, lending to a "Yoda" like post. :D

Wise is he, and friendly too, no offense intended to him I am sure. :D

Larry, certainly you knew what Dillon was saying, I mean after all those years with Moe, Shimp, and Curly, anyone else could be understood. :D
