GBB, TBB, and the combined shunt/negative bus bar

Post by sfrank » Tue Jul 17, 2007 2:59 pm

Hi,

I've seen in the Outback literature that comes with my PS2DC that the negative bus bar included in the PS2DC is bonded to the PS2DC chassis by default. If, however, I want to use a GFP/2 for ground-fault protection, then having this premade bond is going to create a ground loop. The literature acknowledges this, and states that the bond may have to be removed to meet local code requirements.

What I haven't seen is a document anywhere on how to remove this chassis-bus bar bond while still maintaining the shunt/negative bus bar in position. It looks like it's not just as simple as taking out the screw and putting on one of those colored feet instead, because if I try that things don't line up.

Is there an official method for removing this bond and using a separate GBB? Where could I find documentation on doing this?

Thanks in advance.

Steve

The instructions for the GFP are on line.

Thanks, that is exactly the document I needed.
