Illusrations of common wire splices and joints?

You can splice wires together in many ways. You can solder them together and then tape them up or use a shrink insulator that shrinks by heating it up. You can strip the wires back about 1/2 inch and then twist them together and put them under a wire nut. Wire splices in a home must be spliced together inside a junction box with a cover. Wires can never be spliced behind a wall. Any splice should be placed where you can access it later on.
