Today’s visit was for partial power loss of circuit. Found receptacle with burnt neutral on outside patio. Circuit is through the home on both floors and garage. Devices through home are backstabbed, brittle, and failing. There is no GFCI protection anywhere in the home and the panel is 50 years old. Customer only wanted to replace the one receptacle and knows the work is NOT WARRANTIED. Work performed today: Replace (1) receptacle on back patio
