Does a terminal box necessarily require wire bonding
The requirement to bond the metal box has not changed. Does the equipment bonding conductor for a metal device box have to be a separate conductor from the equipment grounding conductor from one of the branch-circuit conductors? Can the branch circuit equipment grounding conductor be bonded to the box and then extended out to be spliced to the other. Mechanical compression lugs have a set screw that tightens on the wire (see Figure 1). The set screw is tight-ened to the National Electrical Code (NEC) recommended torque values as shown in Table 1 to secure the wire. However, Article 300 does not apply to signaling and communications systems, which are covered in Chapters 7 and 8unless Article 300 is specifically referenced nor to integral parts of equipment [300. You must install. Outlet box: An enclosure for conductor splices and device mounting (receptacles, switches, lampholders, etc. 6 (A) provides the minimum bending space at terminals and the minimum width of wiring gutters, based on wire size and the number of wires per terminal. Note that this applies to power cables.
