What's Wrong Here?

Find the Answer

This type of cast metal box did not come with a knockout in the side --especially an oversized "oblong" one. This opening was probably made to accommodate the circuit conductors that were needed to supply the lights on a nearby dock. This seaside location, with its accompanying frequent storms and high winds, created lots of movement among the components, which eventually pulled the connector from the opening. We can see the installer used reducing donuts in this particular installation. However, the locknut was probably not tightened properly. Still, this was not the recognized use of the product and violated the requirements of 110.2.
