Frequently Asked Questions

AI
A back box is typically the recessed or surface-mounted enclosure that holds the device (like a switch or outlet) against the wall. A junction box is often used to connect wires and may not always hold a device faceplate. Some products serve both functions.
Standard plastic boxes may not be suitable for direct exposure to weather. Look for boxes with IP65 ratings or higher, made from UV-resistant materials, to ensure they are dustproof and waterproof for outdoor use.
Depth depends on the number of wires and devices. Standard single-gang boxes are often around 1.5 inches deep. For complex wiring or thicker devices, deeper boxes or extender kits are necessary to prevent overcrowding and ensure safe connections.
