Came across a few situations recently that got me thinking. Situation #1: Installed a service disconnect that had three switches as the main. The service conductors were 205 amp ampacity and it was a 400 amp MLO I-line panel. Inspector said I needed a plaque stating that the ampacity of the conductors was 205 amps. This is a state code (WAC) here in Washington that I did know about but it slipped my mind. i understand the theory that someone could see the 400 rated panel and connect a feeder or branch circuit that is more than 205 amps. Situation#2: House that is fed from a meter/main on a pedestal several hundred feet away. The house is fed with a 125 amp feeder not service conductors. The HO was picking up the panel and I told him to just grab a 200 main breaker panel because it only needs a disconnecting means not overcurrent protection and the 200 amp panel has more spaces and is basically the same price as a 125. Situation#3: You have some 15 amp rated circuits that for any number of reasons are 12 gauge going into the panel. When this happens I label them "15amp only". Is there anything in the NEC that would require labeling that the capacity/rating is not what it appears in these or similar situations?
