I was at a house the other day that had a single 100 amp service that connected to two meters (pic). First question, if the home is not split into apartments, is the second meter always an off peak meter? This second meter (on left) was connected to its own main panel with its own 100 amp breaker (incorrect wire gauge) connected to all sorts of appliances you would not want on an off peak circuit (stove, refrigerator, ect). The main meter (right) was connected to another main panel with its own 100 amp main disconnect. This panel had another 100 amp breaker that fed another main panel in an outbuilding with its own 100 amp main disconnect (which was double tapped with another incorrectly gauged wire to another main panel in another outbuilding with its own 100 amp disconnect). There was also a federal pacific sub-panel in the garage, and another sub panel in a closet off the kitchen. Is it ever acceptable to have the same size breaker as the main disconnect in a panel to another, and so on? Thoughts? Click to Enlarge 39.66 KB
