Installing a new outlet box in a paneled wall is certainly something you should leave to a qualified electrician. In this blog, I will demonstrate this process through a series of photos.
First, I razor cut the box outline and reveal the plaster beneath.
Then, with a dremel plaster blade, I cut the outline and with a knife I remove the loose plaster revealing the wood lathe beneath.
After that, with the lathe cut on both sides, I break off the remaining pieces with pliers, and I shave the excess wood with my razor knife.
