Hi I have been noticing a burning smell from one of the walls in one room of the house.I called the electrician to take a look at it but he could to figure it out as I could not reproduce it during day.Apparently it happens only at night when I switch on the lights of that room for a prolonged period 10 -20 minutes.Any ideas about what could this possibly mean and how to get it diagnosed as it seems to happen at night
