Hello,

I am looking at a design where it is a ground-mount solar array with a customer owned transformer. The current design has a Neutral-Ground bond at the transformer secondary to a GEC with SSBJ's from the transformer to the Solar Disconnect (480V). At the Disconnect we then have an isolated neutral.

Per 250.30(A)(1) Exception No. 2, I am being told that we can remove the need for SSBJ's and have a System Bonding Jumper at both the Customer Transformer and the Customer Disconnect and remove the need for SSBJ's and only run the 3 phases and neutral between the Customer Transformer and the Customer Disconnect. Is this correct?
