How to secure the wires in the bathroom electrical distribution box

Once rough-in wiring is complete, secure devices, such as switches and receptacles, into their electrical boxes. Carefully fold or “dress” the wires into the box to avoid strain on the terminals or damage to the insulation before fastening the device. This dedicated circuit uses 12-gauge wire and handles. To properly secure electrical wires, you must fasten them within 12 inches of every junction box and at intervals of no more than 4. 5 feet using NEC-approved staples or straps. But I'm going to show you a common mistake that people make when wiring them so that you can be confident in making your own wiring safe and secure.
