I saw a panel the other day that still has me scratching my head. It is an old GE with 8 breaker slots total. The buses are split left and right and the pair is fed or feeds at the top. First concern. If this panel is installed the way the labels are right side up, the top breaker on on when the handle is down so to be legal it has to be mounted sideways. This can be set up either as a main breaker panel or MLO on the label.
The one I saw was MLO with two 240v breakers and two 120v 20a breakers, (one on each ungrounded conductor because of the bus layout). So far so good other than the panel orientation.
Now the real question. There was no neutral bus, only a ground bar, attached to the can. The two neutrals were under a wirenut, connected to a white 12ga running along with the feeder from the main panel.
I know it us ugly but is it legal?
The neutral is not regrounded and 408.41 seems to be satisfied.
Grounded Conductor Terminations. Each grounded
conductor shall terminate within the panelboard in an individual terminal that is not also used for another conductor.
Exception: Grounded conductors of circuits with parallel conductors
shall be permitted to terminate in a single terminal if the terminal is
identified for connection of more than one conductor.
I thought the catch might be "terminal" but 110.14(A) doesn't preclude a "splice".
A) Terminals. Connection of conductors to terminal parts
shall ensure a thoroughly good connection without damaging
the conductors and shall be made by means of pressure
connectors (including set-screw type), solder lugs, or splices to
flexible leads. Connection by means of wire-binding screws or
studs and nuts that have upturned lugs or the equivalent shall
be permitted for 10 AWG or smaller conductors.
What am I missing?
