How to drill holes in a plastic electrical box

3. Iron wire or iron bars: This is a relatively primitive method, but it is also very effective. Once the wire or rod is red hot, punch holes in the PVC electrical box. If you need a large hole, use a large thick iron bar; if you need a small hole, use a thin iron bar.

4. Awl and lighter: This is a simple method, especially suitable for making small holes. First prepare an awl and a lighter, then heat the awl until red hot, and then directly drill holes in the electrical junction box. To get neater holes, it is recommended to punch the holes from the reverse side of the plastic.
