Judging by the long and narrow dimensions of this box, it looks like this was home to a SqD XO frame or an ITE pushmatic breaker frame at one time...
Do the circuits in this Jbox terminate in the panel to the left through the single large MC raceway (a wire-fill issue here)? Are there multiple neutrals pulled through the same raceway and landed with the existing neutrals on the same buss (double-lugged)? Did the open neutral occur in this Jbox?
Is there a cover of some sort for this Jbox (possibly removed for the pic or during servicing)?
