Original call was to check the intermittent power in the kitchen lighting. I noticed improper connections to the switches and receptacles, stab in method was used. When I inspected the panel I found scorched and loose breakers. In addition upon inspection of the meter and main breaker located in the meter stack I found the breaker was damaged and weathered. This breaker at the meter was loosing an entire phase. I recommended that this breaker and the panel as well as the kitchen lighting circuit be restored to new condition. We replaced the breaker at the meter stack (Siemens 100A), the existing panel and replaced all devices on the the lighting circuit for the kitchen ensuring proper terminations.
