So when built my lake house I put electric fireplaces in all bedrooms and living areas. Knowing what they run for power I ran single plug-ins with 14gq wires all ran to their own 15amp breaker. Well last night a friends family was staying at the house, and they smelt something burning and I found this. Breaker didn't pop, it just melted the wire. Any reason the wire would caught fire and melt like that? I'm thinking of replacing all the fireplaces now.
