My boss and I are having a disagreement with the sizing of a raceway bond. We have a 600amp service, with Parallel 350's fed underground to a distribution panel through pvc. I,m saying we need to have 1/0, and he is telling me #1. I'm a little confussed on where to find the sizing of this conductor. Should it be based on 250.66?

Never mind....I had a brain fart and forgot to look a little further...250.122. I lost. Now I owe the boss lunch.

Now you've got me confused. Why are you bonding PVC? If the parallel 350's were copper and in a metal conduiit, the bonding conductor would be 2/0.

Or, are you bonding a conduit that is after the service disconnect & overcurrent device?

Few things are harder to put up with than the annoyance of a good example.

I am bonding heavy wall conduit stubbed down, then changing to pvc underground, then back up in heavy wall again. And yes it is after the overcurrent device.
