One inch.
Electrical wire sheathing should not project by more than one inch into where the wire terminates into a specific device. An example is a junction box or branch circuits terminating into a distribution panel.
Electrical wire sheathing should not project more than about one inch into the electric panel.
Electric wire sheathing should not project more than one inch into the electric panel.

The electric panel is something into which electrical wire sheathing shouldn't project more than about an inch. There are recommended guidelines, and non recommended actions, in electrical work. This is such a case, of recommended actions regarding sheathings and panels.

No More than 1/2" into any Raceway Fitting or Box for NonMetallic Cables. Armored Cable (Type AC) or MC should seat to the end of its associated UL Listed Fitting with the Correct Antishort/RedDevil bushing inserted into the end of the cable to protect the wires.
For a 30 amp electrical project, it is recommended to use a 10-gauge wire.
Electric Panel ---------------------------- Based on the answers you have proposed, Electric Panel is the correct choice. However, I do not know of any requirement in the NEC that prohibits the sheathing from extending further into the panel. There is a requirement that it must extend through the connector, but I know of no NEC requirement on when it must stop. --Sparkfighter
The most common wire ran in 120v residential is NM (Non-metallic) sheathed wire such as the brand Romex. 14 gauge wire generally has a white sheathing and can be used on 15 amp circuits such as lighting. 12 gauge wire is thicker, generally having a yellow sheathing and can be used on 20 amp circuits such as those serving receptacles. Considering future demands, 12 gauge wire should be used. Under no circumstances should you ever use 14 gauge wire on a 20 amp circuit.
