Electrical boxes are the hidden workhorses of your home’s electrical system. They house the connections between wires, providing power to outlets, switches, and fixtures throughout your house. But like any electrical work, safe and proper installation is crucial. Here at Allied Moulded Products, a leading manufacturer of electrical boxes, we want to help you ensure your electrical boxes are installed safely and correctly. Whether you are installing our tried-and-true Fiberglass electrical boxes or any of our flexBox products, we’ll discuss some key do’s and don’ts of electrical box installation.



  • Use the right size and type of box for the application. Different electrical applications require different sized boxes. Make sure the box you choose has enough space to accommodate all the wires and connections without overcrowding. Allied Moulded Products offers a wide variety of electrical boxes to suit a variety of needs, from air-sealed boxes for external walls to fire-rated boxes for added safety.
  • Turn off the power at the breaker box before starting any electrical work. This is the most important safety rule. Always double-check that the power is off before working on any electrical wiring.
  • Make sure the electrical box is level and plumb. A level and plumb box will ensure a secure installation and make it easier to connect the wires.
  • Secure the box firmly to the stud using the appropriate fasteners. Use the correct screws or nails to securely fasten the box to the stud. Most of our products come with the screws or nails you would need to properly install one of our electrical boxes.
  • Leave enough slack in the wires to make connections easily. You don’t want to put any strain on the wires when making connections. Leave enough slack so that the wires can be easily maneuvered within the box.
  • Use wire connectors approved for the size and type of wire you are using. There are different types of wire connectors for different applications. Make sure you’re using the right type of connector for the size and type of wire you’re working with.



  • Use a box that is too small for the number of wires that will be installed. An overcrowded box can lead to overheating and electrical problems.
  • Overload the box with too many wires. As mentioned earlier, too many wires in a box can create a fire hazard.
  • Use damaged or undersized wires. Damaged or undersized wires can pose a serious electrical hazard.
  • Make connections inside the box that are not secure. All connections inside the box should be tight and secure to prevent electrical problems.
  • Forget to ground the box. A properly grounded box is essential for electrical safety.
