panel upgrade

[hotwire81]

Just wondering if there are any codes stating, that either you can or can not, in a panel upgrade use the existing panel box for a junction box after removing bus and bars. Help is greatly apprieciated.

Make proper splices and joints, ensure proper enclosure bonding, and ensure the cabinet is of proper size to accomodate total fill.

It would also be a good idea to add wire labels and identify all circuits.

Boxes are not required to be listed. So long as your box meets the construction specifications of 410.40 - 410.44 and you close all unused openings (110.12), I would allow its use. The building code requires the re-use of used equipment to be approved by the building inspector, however. If it were convenient, I would pre-approve it's use with the BO prior to completing the job. Might save a lot of work later. NEC 110.2 also requires all equipment to be approved by the AHJ.

I believe you meant 314.40 - 314.44.
