low voltage electrical splice?
I have low voltage lighting in my yard. There was a break in a long run of
wiring. I stripped the ends, spliced together (twisted), covered with vinyl electric tape and everything seemed to be working. Then the wire burned through at the splice. The ends seemed to be corroded through . . . covered with green corrosion. This has happened twice at the same spot. Any suggestions as to why this is happening and what to do about it? |

The best thing to use is a gel filled underground wire nut, such as "king one step" or Ideal "underground wire nut" |

It's probably getting damp, corroding, and then the tape burns through because of the high resistance. I would resplice it but this time use heat shrink, solder the wires together, put a thin coat of silicone grease over that, then slide a LONG piece of heat shrink over the splice and shrink it down. If that doesn't work you'll have to replace the wire with one that can be run continuously. good luck nate -- replace "roosters" with "cox" to reply. http://members.cox.net/njnagel |

Of course, you may have developing pinholes in the insulation leading to new failures, too. If it fails yet again after the above repair, replacing a section or the whole run may in the cards soon. -- |

Cheap, lasts forever. You'll need to strip back to find nice clean copper. Twist together tightly & solder away. You can even get out of acquiring any soldering equipment -- just stop by Radio Shack (maybe elsewhere, but not positive) to buy strip solder. It's a package of little strips of solder, each the size of a match, and you wrap your connection with a few of these and apply heat. |

Hmmm, How about using a wire nut and fill the nut with Si sealant, then wrap it tight with tape. |
