The choice of not adding a breaker for the feeder is mitigated by this:
- The current panel is an early 60's CH with 120 on one side, 120 on the other - there are only two 240 slots int he panel
- the current breaker is a 4-position 100 "beige" CH taking up both 240 slots - the clips on the other side of the breaker act as the hold-down for this back-fed breaker feeding the panel.
- Using a smaller 100 breaker for two slots would offer no hold-down for the main.
- Changing this units main panel would trigger the changing of the whole service for the multi-unit building. (Something they want to do anyway, but not yet.)
- The building is still a TIC, but will need some heavy work during condo conversion soon - to include this and the rest of the units and house metering.
Either way the Inspector is working from opinion rather than code IMO, and on my customers behalf, I get the fight for it....
