On construction sites, a box shall not be required for splices or junction connections where the circuit conductors are multiconductor cord or cable assemblies, provided that the equipment grounding continuity is maintained with or without the box.
You have to be able to maintain electrical work. For instance, If you have a splice in a non accessible J-box go bad, or, if in conduit with no splice, and, the wires comes into the J-box then out in a way that you couldn't pull new wire from both ends if needed, you're screwed.The 2005, 2008, and 2011 editions of the Code give permission for installing a splicing device inside a wall space (concealed) without a junction box if you are rewiring a house and need to extend a wire. There is one exception: There are certain types of splices permitted inside walls without a junction box. That can save a lot of time & trouble for certain repairs, with the presumption that these splices are super-reliable and won't need future access.
300.15 explicitly requires a box unless one of those insulated NM modular splice connectors is used. 300.12 precludes making a splice without a box or insulated connector. You must install a box or conduit body at each conductor splice connection point, outlet, switch, junction, or pull point, with exceptions in these sections: 312.8 — Cabinet or Cutout Boxes 820.3 — CATV Junction boxes must be grounded to provide a path for fault current to return to the source and to prevent electrical shock. Using an approved grounding method, you must connect the grounding conductor to the junction box.Electrician Explains Electrical Codes for Home Electrical Junction Boxes with Photos, Wiring Diagrams and Answers to Your Questions
Splices in electrical wire that carries electrical current in a building (such as for lights or electrical outlets) must be completed using an approved mechanical connector and must be enclosed in an approved junction box which itself is secured to the structure.
