Bonding with irreversible crimps

[AZpalmtree]

I have a 24x24 j-box with 500mcm brown, orange, yellow and a 500 ground. They are spliced with irreversible crimps and sealed with shrink tube. If they are just passing through the j-box, do you need to bond the box since the splice is sealed.

Yes, it is required. 250.148.

Edit to add: That is to say, since there are splices the EGCs must be spliced and attached to the box as well.

If the conductors did not get spliced within the box, the box would still need to be bonded in some fashion (such as by metallic raceway) but the EGCs passing through the box unspliced (with the unspliced circuit conductors) would not need to be connected to the box.
