	Subject - run capacitor grounding kingofmars ok I dont know if this is the correct forum for this question but maybe I can get some input anyway, my question is since the NEC puts such a high priority to equipment grounding, and rightfully so, why are motor run capacitor not designed with some sort of grounding method, some are actually mounted in a rubber sleeve, are there pros and cons on this, has this been overlooked, or do we feel that it is insignificant, I am presently building a rotary phase converter and am going to mount my caps in a non conducting clamp setup and was just curious if anyone has any opinion on this, thanks, king JimmyDee I would think you would want to install the caps in a metal box that will be grounded. I would do this for several reasons. First is to enclose all the open wire that will result from the wiring. Second is that when caps go bad, they tend to go off like a M-80 and I wouldn't want to be around if and when one goes. Third is I think this would be required by the NEC but don't have an article number for you. Mounted in a box, grounding of the caps is moot. Jim kingofmars actually I am mounting everything inside of a hoffman box but I am only refering to the housing of the capacitors themselves, there is no way provided for the grounding of them, the code states that all conductive equipment that houses current carrying conductors or aparatus shall be effectively grounded per NEC 240.4 but this seems to be overlooked when it comes to motor run capacitors. Most equipment manufacturers simply lay them inside panels and therefore they are insulated by the panels paint or they mount them in insulated clamps and they will have no grounding in that situation??
