Yes, it's okay to use a plastic junction box for indoor applications where it is less likely to be exposed to extreme conditions. Plastic boxes are lightweight, resistant to corrosion, and simple to install. They are ideal for residential wiring projects, allowing for easy adjustments. However, avoid using them in locations requiring high durability or in areas with high heat, which could lead to deformation. For these conditions, consider using metal junction boxes for better strength and fire resistance.
