Service panel for a condo has 6 AWG CU coming down from meter. No main disconnect, just a 60 amp breaker for the apt sub panel, a 25 amp breaker for the heat pump condenser, and a 15 amp breaker for the gas fueled hydronic boiler and tank water heater (in basement). All the conductors attached to the breakers are appropriately sized.
I’m wondering if the 6 awg feeders are enough or if they should be called out. In theory, close to 100 amps could be running through the feeders, no? I realize in practice it is much less, but figured the wire should be rated for the max. I’ve seen this setup before and called it out, but an electrician was needed for so many other things that it was an easy thing to have the electrician check. Same as last time, there are other defects in this panel so I’m adding this to the list again, but I was curious what others thought.
Also, on a different note, how many of you call-out a white, unlabeled grounded conductor being used as a ungrounded conductor when it is for the 240V to the condenser and it’s a straight run there (as seen in this panel)? I do to cover myself, but I don’t really feel like there is much risk since anyone working with that wire at either end would know that white wire is most likely hot. Again, asking out of curiosity.
