This is an electrical panel in a brand new Houston area condo with a faulty breaker/bus connection. It was located during an infrared thermal inspection that was performed as an optional part of a Houston home inspection. If the outside of the breaker shows a 200+F° rise, just imagine how hot it is at the internal connection. This Delta-T rates as a Critical exception on the interNational Electrical Testing Association (NETA) scale.
Every new home comes with built-in defects. Don’t let anyone tell you that a new home does not need an independent home inspection or that performing an infrared thermography inspection on electrical systems in new construction is a waste of time. The only way to locate and quantify this particular electrical defect is through the use of infrared thermography.
