The definitions for Class 2 circuits can be found in Article 100. In the last issue, we discussed the general requirements that apply to Class 1, 2, and 3 circuits. Some general requirements in Part I of . There is no code requirement for class 2 circuits to be spliced in a box. Did you read 725.3 as Chris pointed out? That code section states that only those sections of Article 300 referenced in Article 725 shall apply to class 1, 2 and 3 circuits. 300.15 is not referenced for class 2 wiring methods.
Is a jbox required? Answer: There are multiple CSI Divisions with Class 2 wiring, look up the spec for the system you are installing, and see if cans and boxes are required. A free-air splice is legal, sometimes frowned upon, sometimes not.
To pass inspection, a junction box must be installed to encapsulate a 120V AC wire connection to a 12-24V DC power converter (driver). Junction boxes provide a safe, grounded fireproof enclosure, preventing wire nuts from coming loose and causing a short and possible electrical fire. Enclosures are not required for Class 2 splices or terminations because Art. 725 does not reference Sec. 300.15, which contains those requirements [Sec. 725.3] (Fig. 1). Fig. 1. These splices do not need to be placed in a box or enclosure. For Class 2 Installation: The 0-10V control wires must be mechanically separated from Class 1, line, neutral and ground power lines. This can be accomplished by performing the following: Installing a mechanical barrier, in the form of silicone tubing or other non-conducting sleeve, over the length of 0-10V (Violet & Gray) control wires .
