Incident overview
A television, coffee machine, air cleaner, and other appliances were damaged at a residence when an electrician was working to install an additional junction box to the electrical system. During the installation, a mislabeled neutral conductor crossed a hot conductor. The neutral conductor, which typically does not have overcurrent protection, became hot when the power was turned on and damaged appliances and other wiring in the cabin.
