In olden days, there is were 120v 2 wire panels. They were commonly called =E2=
=80=9Cwoodshed =E2=80=9C panels, and were used in farm outbuildings. You ha=
d more than a single circuit load, but not much more, and it saved a wire. I=

In general you can=E2=80=99t have two wires under a lug. They are not design=
ed for it, and can come loose. You can put more than one ground wire under a=
screw if the bar is listed for that ( most are). You cant put more than one=
neutral under a bus screw, because of the risk of disconnecting a neutral f=
rom a live circuit.=20
Some breakers, notably homeline ones, are rated for two wires. Inspectors s=
till call it out, because it=E2=80=99s on their checklist. (The guy who insp=
ected my house called that out, but not the 50a 120v breakers with 14 gauge w=
ire. What the hell uses 50a 120v, btw? They had done it so outlets didn=E2=80=
=99t trip the breaker. ).=20

My concern is that while the Neutral bar has four positions on a common ba=

the two. This surprised the heck out of me. My inverter (Victron 24/70/300=

stud terminal which would be easy. I can run a 6 or 8 AWG from the inverter=
to the Breaker box, but it needs to go to the two separate screw down termi=
nals. Physically, I believe I can run an 8 AWG wire into one breaker, and t=
hen back out to the other breaker, but I?m concerned about whether this is a=
code violation.
