How did this happen ?
** Take a careful look at the damage to this mains plug. A very specific but not so rare event caused it. It is also a potentially lethal event. ....... Phil |

Phil's picture leads me to think that the Earth terminal should be top to divert any debris that might land upon the circuits. I have a lathe plugged into an outlet that at least once had been shorted out by flying debris. As a work-arround, I put a seam of caulk arround the plug and socket to keep anything from falling within the connections. One of these days, will have to convert to twist-lock connectors that seal much better. Oppie |

news:OOsGj.2355$rb6.245@trnddc01... Phil's picture leads me to think that the Earth terminal should be top to divert any debris that might land upon the circuits. The physics electronics shop where I worked as a student hourly in college years ago was done this way. It is a good idea, although I'd admit to be too "bothered" by having just one or a few outlets "upside down" that I've never done it when I've replaced an outlet or two in a house. |

In Oz of course they should point towards the east. |

I think I read in the NEC they now demand that new installation of any kind orient the ground lug at the top. My old NEC code (late 90s) book only suggested ground-pin up. Most installations put ground-pin down because it looks better. |

Thanks. The 60309 style or something very similar is used in the USA on
temporary industrial hookups. I've seen it most commonly used in charging stations for electric fork lifts and on occasion, on an outdoor utility (telephone?) underground vault cover. For my purposes, way to expensive and twist lock it most likely the way to go. Most likely will put a dangle receptacle on a short cord and then a male on the line from the lathe. Object is to keep the mating plane nearly horizontal so that chips can not fall into the terminals. Then again, large machines are required to be hard wired by semi-flexible conduit into a disconnect box... cheers - oppie "Eeyore" wrote in message ...

The Home Depot and Lowe's hardware stores carry a weather enclosure which would seem to be both cheap and an easy way to prevent debris from falling onto the plug / socket. You might also move the outlet up the wall. |
