Romex comes in different sizes and configurations, with the most popular being 12/2 and 14/2, indicating the gauge of the wires.

Also known as Non-Metallic Sheathed Cable (NM), it consists of two or three insulated conductors housed in a plastic sheathing. Romex is a type of electrical cable that is commonly used in residential wiring. It’s important to make sure that the Romex is not pinched or crushed by the hole, as this can cause damage to the insulation and create a potential safety hazard. For 12-gauge Romex, the National Electric Code (NEC) recommends a minimum hole size of ¾ inch, while for 14-gauge Romex, a minimum hole size of ⅝ inch is sufficient. When it comes to drilling holes for Romex, you’ll need to make sure that the hole is big enough to accommodate the cable without damaging it. The jacket is a key feature of Romex since it protects the wiring from damage and helps to prevent electrical shock. Romex typically consists of two or three insulated wires (depending on whether it’s 12- or 14-gauge) sheathed together in a single jacket. Romex refers to a type of electrical cable that’s commonly used in residential applications to power outlets, switches, and lights.
