Inspected a home with a Square D main service panel and a Cutler Hammer sub panel (30 amp breaker from the main). I believe that the Cutler Hammer sub panel was the original installed in the home and converted to a sub panel when the Square D panel was added. The home was a 1951 build.
In the Square D panel, a 30 amp breaker on the upper right side (labeled for dryer) was attached with an old conductor on the upper half of the breaker. This I presume was going to the dryer. The newer conductor attached to the lower part of the breaker appeared to be a #12 that was providing service to an exterior receptacle and light. When I tested the dryer receptacle, it did indicate 240 volt service. I am confused since it appeared that only one conductor was attached for the dryer (upper half of 30 amp breaker). Also, if not mistaken, the exterior receptacle and light should be attached to a 15 or 20 amp breaker not 30 amps. On a separate issue, should the white conductors on the 30 amp and 50 amp breakers in the Square D panel be wrapped with tape to indicate that they are now hot.
In regard to the Cutler Hammer sub panel, I am recommending that the panel be further evaluated since it appears to be outdated to today’s modern wiring requirements. Any comments on this panel would be appreciated.
By the way, go Broncos!
