This is the first time I’ve seen the EGC bypass the service panel. The installation was 1984. Was this something that was allowed back then? There was a smaller grounding conductor that went from the meter to the service panel.
The first distribution panel was nicely wired, but all sorts of issues: grounded and grounding conductors not separated, bonding jumpers on egc bar, double-lugged grounded conductors, double-lugged service lugs, etc.
