Why should there be no bare wire exposed after a wire nut is used?

Leaving any exposed bare wiring can lead to short circuit and breaker tripping. Most of the times wires in junction boxes are jammed into the back of the box. This is to allow for a device such as a switch or receptacle to be installed. Leaving exposed wire showing below the wire nut could allow contact with other exposed wires or it could come in contact with the bare ground wire which is also jammed in there. Good workmanship should prevail, only strip as much wire as needed to twist the wires together. Then install the wire nut. The skirt of the wire nut should project down over the insulation of the wire by a quarter of an inch. If it does not use a larger wire nut. This will provide full insulation protection to the wires in the junction box.

What type of prewire for a ceiling fan light?
The pre wire for a ceiling fan light should be made with a three wire cable. This cable will have a red, black, and white wire as main conductors. This cable will also have a bare ground wire. This wire should be strung between a two gang switch box to the fixture junction box. This pre wire allows the supply to be either fed to the two gang box. From the two gang switch junction box, one side will be used for the light in the fixture and the other side of the switch junction box, itwill be used for the fan portionin the fixture.
Is a copper wire a ground wire?
Yes, if it is not an insulated wire. If it is bare copper it is always ground. But the hot and neutral wire are also copper, they are just insulated.

What purpose does the plastic cover and the copper in a wire serve?
The copper is a good conductor of electricity. While the insulating plastic covering of the wire prevents bare wires touching and creating a short, or shocking (electrocuting) a person should the bare wire be touched with bare hands.
Why you use cut mark in three pin plug?
It is used to show the correct length that the wire has to be stripped to make a perfect termination. By using this mark no bare conductor will be exposed when the plug is assembled for use.
Are speaker wires waterproof?
Bare wire will rust and is not waterproof... the plastic part around the wires, like all plastic (cups, intertubs etc) will not and is water proof. However I would not recomend keeping any wires close to water as bare wire could be exposed.

What is the color of insulation over an earth wire?
The insulation will be green in colour. Also bare copper can be used as a ground wire.
In the United States is a neutral wire used in 120 VAC circuits?
Yes, in most cases it is the white wire. (the black or red wire is the hot and the bare wire is the ground.)

Yes, as long as it is the same size wire or larger as the hot and neutral wires.
