Reusing parts from electronics panel

[McGeekin]

So far we have been doing a good job reusing parts we saved from the demo of our Collins short bus(4window). The interior walls have to be saving us hundreds in sheet metal cost and we have even found a use for a few of the heavier duty wires that were removed.

I am wondering though if anyone has any bright ideas on these parts from the electrical panel. If i can use any of them in the house system?

Go ahead and drop a line if you have or known anyone who has come up with a use for these in the build process.
Thank you!
