Wires are not to be spliced or otherwise connected except in an approved electrical box. The box should be accessible, such as an electric outlet or switch box. If you decide to NOT use the box as an outlet or switch box, make certain that you use a blank cover.
Yes as long as you use an approved splice, such as a wire-nut.
Yes, you splice a small length of 16 gauge wire to 18 gauge wire for a repair.
There are two types of thermostats. One is line voltage and will require a splice be made in the old thermostat junction box . From the old box a new cable has to be pulled to the new thermostat junction box. This wire must be of the same size as the existing wire.The other type of thermostat is low voltage thermostat. This uses usually # 22 size wire and because it operates on low voltage it does not need a junction box to make a splice in. Solder and tape the new wire on to the old piece and then take it to where the new thermostat is to be located.
The answer depends on what type of access you have to the junction box. The wire external to the box may have some slack that can be brought into the box. If everything is tight you will probably have to install one or more additional junction boxes or rerun wire from electric panel. As an example assume that the short wire has no external slack, but you can install a new junction box near the other box and in the path of the short wire. 1. Pull the short wire from existing junction box. 2. Install new box in path of short wire so more slack will be available in the additional junction box; and pull wire into new box. 3. Run a wire of the same size from new to old box and re-splice any connections for original short wire or new connections; and connect this new wire to the original short wire in the new box. Make sure you follow all code requirements for your locale.
The electrical code states that any splice in a wire, the insulation over the splice has to be equal to or greater than the insulation on that of the rest of the wire. So what ever type of splice that you use make sure that you insulate it well.
Yes, but you have to do it correctly. You should use 10 AWG wire. The splice should be in an approved electric box using the right size wire nuts. You secure and protect the extended wire and you should not "bury" the splice box in the wall, but cover it with an approved cover made for the purpose. If it is a surface mount box, cover it with a blank metal cover.
The only way you can splice Home electric wiring is with a junction box. Any other way will and can cause fires.
One splice that would work is a western splice.
Yes as long as you use an approved splice, such as a wire-nut.
A wire splice is the joining of two or more wires together. Commonly this is done with an approved wire joining nut. All slices are to be made in junction boxes to prevent fire should the wire splice become unserviceable.
I thought so. A buyers home inspecter says the splices,connections must be in a box "as per code".
Yes, you splice a small length of 16 gauge wire to 18 gauge wire for a repair.
A 240 volt wire is the insulation factor of the wire. If you mean a 240 supply source from a distribution panel to a junction box then the answer is yes. You have to keep in mind that the box has to be accessible, meaning that you can get to the box to check the splice within the box. Don't bury the junction box behind the wall board.

Splice uses stranded wires while joint uses solid wire.
