250.102 (C) (1) Table Q

[zcanyonboltz]

250.102 (C) (1) is used to size bonding jumpers, I don't understand why the table says Grounded Conductor? I thought grounded conductor was sized using 220.61 and by doing calculations based on article 220? Thanks

The grounded cannot be smaller than what is shown in the table. It is the minimum size.

We used to use table 250.66. CMPs felt the need to copy and paste that table into 250.102.

Somebody needs to find these guys something to do where they can all sit around and still feel important.

I think there is one small difference in the tables IIRC. Do not have book at the moment.

Having the additional table gets rid of the problems with changes you had to make to T250.66 where you were using that table for something other than sizing the GEC.

Somehow we managed for forty years.
