What are the key differences between a metal junction box and a plastic junction box in terms of durability and safety features?

Metal junction boxes are generally more durable and fire-resistant compared to plastic junction boxes. They provide better protection against physical damage and are less likely to melt or catch fire in case of a short circuit. However, metal junction boxes are conductive and may pose a risk of electrical shock if not properly grounded. Plastic junction boxes are non-conductive, making them safer in terms of electrical hazards, but they are not as durable or fire-resistant as metal junction boxes.
