That looks good Andrew, you can't do with water dripping into the foundry! Phil |

I’m getting a bit neurotic about this Phil! But water, molten metal and high voltages at high frequency don’t bode well :bugeye: I don’t think I’m out of the woods just yet but this should solve two of the three water sources when I’ve fully sealed the ends of the threshold strip to the shutter frame. |

seeing your three phase overheads reminded me of a visit to a farm many years ago where an ancient old boy in plus fours showed us a problem with his 3 phase mill mixer unit, when it failed to start, and growled, we immediately sussed it was off a phase, but the old boy said "nay lad, thats summat else" grabbed a long peice of wood, wandered outside and began to poke at the line taps on the overheads! when the guy I was with shouted at him to stop, he said "Why its areet as long as't woods dry, otherwise appen thoo'l get a tickle off'n it!" Needless to say we fixed the problem (star delta coil failed on an old Memota side handle starter) and also refitted all the line taps so he didnt get fried! Phil |

Those overheads feed my 160 amp per phase supply - I reckon they'll get mighty warm at 160 amps - the feeds down the barn wall to the current transformer metering gizzmo are only 6 mm aluminium but they insisted on huge copper meter tails - can't remember the specifics but it was more than 50 mm csa ! |
| hermetic:
Well Andrew, if the aluminium evaporates at least its their problem, not yours! Phil. |
