Question – Attic Insulation and Wiring

By Dave Rongey - Summary:

Attic electrical wiring covered with insulation poses a concern about over-heating.

I have a garage/workshop with wiring run through the frames, but not in the electrical tubes. Is this OK to insulate or will the wire generate heat?

As long as the wiring is newer Romex type wiring and the circuit breaker is sized correctly there should be not problem with insulation.
The newer Romex has improved insulation qualities with wiring such as 14/2, 14/3 12/2 and 12/3 etc.
Old Knob and Tube style wiring does however pose a problem with insulation.
