14-2 and 12-2 spliced together

[monkey_man_100]

I trimmed a house today and the guys who ran the central vac put a 12-2 NB in a outlet that we had next to the vac hook up (14-2). They created box fill on some boxes that we had to fix. Something seems wrong. Could someone refrence a code so I can study up on this. Thanks

The central vac is covered under 422.15 and 210.23(A)(1).

What specifically are you looking for. Do you want box fill info, etc?

Are you questioning the 12/2 to 14/2 connection? If the circuit was run in 14 and the OCPD is sized for the 14, 15 amp, then you can up size the conductors, 12. You just cannot go the other way.
