Thanks in advance.
I am installing a light fixture with three wires: Black - Hot White - Neutral Copper - Ground The Junction has four wires coming out. They are all capped as this junction box has never been used. They a Black White Green which is ground ?RIGHT?? RED ????? Do I forget the RED wire and leave it capped?? Some of the other posts mention RED wire used with a FAN??? |

Some of the other posts mention RED wire used with a FAN??? Green or bare is ground, white is neutral. If you have one wall switch, you need to see which of the red or black wires are hot, when the switch is on, and dead when it's off, and use that wire for the "hot" of the fixture |

Some of the other posts mention RED wire used with a FAN??? Maybe one leg of an old three-way switch? About twenty years ago, when I bought my present house, I converted two three-way swtches to one single-pole switch. I capped the unused switch box and covered it with drywall. I can't for the life of me tell you exactly what I did, but it's been twenty years and the place hasn't burned down. |

It is possible that you have a pre-wire for a ceiling fan. Black for
fan, red for light. White neutral, green/bare ground. See if you have 2 switches at the wall. Otherwise, see if Red-white or black-white is switched. Cap the remaining red or black, as the case might be. |

The black should be hot regardless of the switch position, and the red should work from the switch. |

Black is HOT RED is HOT One is HOT ALL of the time One is HOT only when the switch is ON Correct??? Thanks again |

That is probably the case. There are three other possibilities worth
considering. 1) Red and black are both always hot. Not likely, but possible. 2) Both are on separate switches. We have this arrangement in a room with two fans, to we can turn both fans on/off with one switch and turn both lights on/off with another switch. 3) It was wired by someone who didn't know what they were doing, in which case, anything is possible. If you have tester (and know how to use it without killing yourself), test it to be sure. |

Oh, and if you don't have a tester, get one. The cheapest one you can
find would be sufficient for this test. Be careful. |

Be very careful with the RED wire. That wire is connected to Washington DC and is used to detonate nuclear weapons. One wrong connection and the whole world is history. The red wire is a spare "hot" line so that you could install two separately-controlled circuits in the fixture if you wish. For example, in a dining room the fixture over the table could have a circuit for general room lighting and another for downlighting/accent lighting on the table. An outlet box where a ceiling fan might be installed could use a circuit for the fan motor and the second one for a fan light kit. That gets rid of the pull cords you see on fans. The red wire is sometimes used for 3-way and 4-way switch arrangements too. I wish including the red wire in junction boxes was standard practice. It's so easy to do when running the wiring and so hard to do later. TKM |

Some of the other posts mention RED wire used with a FAN??? A red wire in hot, just like black. The electric code makes no distinction between red and black; it's up to the installer how they are used. Maybe the red wire is switched and the black is hot all the time, or vice versa, or maybe the are each on different switches (one for the fan and one for the light.) The white wire is almost always neutral (and if it's not, there should be black or red or blue etc. tape on the end to tell you that it's /not really/ white. The green wire is always ground. Put a test lamp between the white and (one at a time) the red and black wires, then play with the switches to see what you've got. HTH, Bob |
