When I wire a panel, the outer insulation of the romex does not extend past the romex connector, after the actual conductors have been neatly shaped to the ground / neutral bar and the line has been brought to the breaker the insulation of the hot & neutral is then stripped exposing 1/4 inch of copper then landed.

The sheathing of a Romex type cable should project one inch into the electrical panel, however it is sometimes not accessible to trim the sheathing back this far due to other cables which may make it difficult, therefore start the trimming where safely accessible.

by code in Manitoba yes it can. and i don't see why it wouldn't be the same anywhere else in the world

Answer for USA, Canada and countries running a 60 Hz supply service.

I scoured the NEC for something on this, believing there has to be a rule somewhere. I found some references to 1/4 inch minimum in various special circumstances but nothing for general conditions and nothing on maximum distance. I still believe there is something there. I'm just missing it somewhere. The NEC is quite complicated.

I used to leave as much of the sheathing as I could because that makes it easier to trace a circuit if that becomes necessary. Over the years I have gotten out of that habit and I remove the sheathing from just within the panel.

Removing the sheathing outside the panel makes it non-sheathed individual conductors with no conduit or other protective means which is a violation of code.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,

on electrical circuits, equipment or appliances,

always use a test meter to ensure the circuit is, in fact, de-energized.

IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB

SAFELY AND COMPETENTLY

REFER THIS WORK TO QUALIFIED PROFESSIONALS.

Yes, there are minimum and maximum lengths in terms of electricity. The interaction of sheathing and panel is a case in point The electrical wire sheathing shouldn't project more than about an inch into the electric panel.

1/4"

In the US the NEC doesn't specify except that the sheath must go through the connector. 1/4" is a good rule of thumb, but tracing wires may be simpler if you have more.

How do you complete a sentence that begins with 'Electrical wire sheathing should not'?

Electrical wire sheathing should not project more than about one inch into the electric panel.


Into what should electrical wire sheathing project no more than about an inch?

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.


Electrical wire sheathing should not project more than about 1 inch into the Aplumbing line B floor joist C electrical panel D ground?

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


Electric wire sheathing should not project?

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.


Why should electrical equipment not be operated near water?

1. Because water conducts electric currents and this would prevent the electric circuits working properly. 2. Wet skin is a very good conductor of electric current and there is a high risk of an electric shock.
