Electrical Wiring in the Home/Exposed Wiring---External Conduit


Hi, Bob. I've an "old" CBS house in Miami (built in the 50's---a lot of DIY by various owners over the years). There's a metal conduit pipe running along an outside wall that was embedded into a thicker section of poured concrete wall by cutting out the concrete and stuccoing over the pipe just under the surface. The pipe makes a right angle turn and heads down to the dirt, going God knows where. I just discovered, after the stucco was pushed out due to the expansion of the pipe from massive corrosion, that, well, the pipe might as well not be there.  The (still insulated) wires are exposed  for an inch or two at the soil line.

I'm asking this question just so someone knowledgeable will tell me to do the right thing, but is there a quick-fix wrong thing that can be done, at least in the interim, such as chipping out the rust and filling the interior of the pipe with caulk so as to protect the exposed wires?

Now go ahead and tell me the right thing to do....



The first question is: do these wires do anything ? Are they energized ? Is there a switch in the house that energizes them ? If you can definetly determine they are obsolete you can cut the pipe back as far as you want to and abandon the pipe and wire going into the ground. It may go to an old lamp post thats not there any more or a recpetacle some where in the yard that you may or may not care about saving. Check it out and see what you find. Then we can figure the right course of action.

"The Frank Williams School of Electrical Construction". My dear old boss is 100 ! and still going God Bless him. I started working for "Tenafly Electric" right out of high school at 19. He was tough but I learned more working for him in 8 and half years than most guys. We did mostly industrial work while doing some commercial and residential so I was fortunate to be exposed to all 3 areas of electrical construction. The guys I worked with were all good guys and I stay in touch with some of them still. Most of us went into our own buisness's which says something about the caliber of the guys I worked with. We had some interesting clients : Wella Corp. of shampoo fame, Farah Fawcett etc, I didn't buy shampoo for 10 years. It was a great place to work. Pan Am the former airline just before they went under, another great place to work, nice clean environment. C&C Metals, the largest button manufacturer in the US at that time, a not so clean environment but a very interesting place to work, lots of machine's cranking out buttons of all kinds but you had to be on your toes, it was a potentially dangerous place to be . All kinds of action going on around you.
