“It is well documented that fragile wiring is exposed to numerous workers and possible damage on construction sites. But seldom do we hear that appliance defects are not scrutinized during shipping or receiving – unless the appliance box appears to be damaged. Therefore, mechanical defects in appliances or hidden wiring damage in construction can easily be overlooked.”
