A Homeowner's Guide to Electrical Boxes
Electrical boxes are required for most electrical installations around the house. Boxes have two very important jobs: they provide means for securely mounting electrical cables and devices (outlets, switches, light fixtures, etc.) in walls and ceilings, and they enclose the wiring connections to protect neighboring materials and people from the electricity. Electrical boxes come in metal and plastic and in a wide range of shapes and sizes. Choosing the right size is important because it's unsafe—and illegal—to cram too many wires and devices into a box.
