PVC Junction Box. The PVC (Polyvinyl Chloride) junction box, or PVC Electrical Box, stands out for its affordability, strength, and lightweight design, making it an increasingly popular choice.. PVC is a nonconductive material. So your PVC electrical junction box won’t conduct electricity if it’s touched by a live wire, a fixture, or a switch (in the case of a fault). This can be done using a suitable mechanical lug (such as an IHI S2-171 with the mounting hole drilled out to .203 for a #10 screw) attached to the grounding screw point in the box with a 10-32 machine screw and nut, then landing the grounding wire from the SER cable on it, or by using a Bridgeport 164 or equivalent grounding locknut on the EMT . To ensure a secure and hazard-free junction box installation, it’s crucial to steer clear of common mistakes that may compromise the effectiveness of the wiring system. Overcrowding the junction box, using the wrong type or size of the box, poor wire connections, and neglecting proper grounding are pitfalls to avoid.
