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.
plumbing line floor joist electric panel ground Electrical wire sheathing should not project more than about one inch into any device that uses a cable clamp to secure the cable to the device.
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.
For the electrical circuit in a kitchen renovation project, it is recommended to use 12-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 used for 120-volt circuits in residential and commercial buildings is typically type NM (Non-Metallic) sheathed cable, also known as Romex. This type of cable consists of two insulated conductors (usually black and white) and a bare copper ground wire. The black wire is the hot wire, the white wire is the neutral wire, and the bare copper wire is the ground wire.
