Q:cf ceiling fanlf old light fixtureI took down the old light fixture and there are 4 wires total; 2 white wires. Then there is 2 black taped off wires. The 2 white wires were the only wires connected, separately to the old light fixture. I tested all of the wires and all are hot except 1 white wire. I assumed that was ground. I installed my ceiling fan as follows; cf white wire to lf white wire. cf ground wire to non-hot lf white wire. cf black and black/white wire to only 1 lf black wire. I taped off the other hot black wire because i didn't think i needed to connect it. Turned light switch on, nothing. Fan does not work, light in fan does not work. Did I connect the wires incorrectly----- HELP! Thanks!

You didn't say if you had a wall switch. This matters. Generally, both white wires are spliced together and these are the neutral. The 2 black wires are both hot. The ground wires are green or bare copper. You should have 2 black wires coming out of the light/fan; these are hot and are spliced to 2 hot wires from the ceiling fixture. Always black to black and cap these off. You hooked up the white neutral wire to the ground wire which is incorrect. If you don't have a ground wire coming out from the ceiling fixture which would be green or bare copper, just hook the ground wire from the light/fan to the metal plate in the ceiling. Good Luck!

Q:If (after shutting the breaker off) I disconnect a switch or outlet or fixture from the feed wire and then turn the power back on (assume I've capped them for safety ) is the white wire (neutral) carrying any power?

NO.not normally.also check the white wire to see if it is the neutral.then you should be o.k.is this what you intend to do.or are you just asking.

Q:It hurts, and then you will be detours later, but the poles are still there! What is the original statement of that sentence! The More

Installed system, if the system will pay attention to the contents of the motherboard disk is the majority of the driver

Q:Will the three-phase selection of electric wire square root with the power between how to choose?

unnecessary. Information points rarely 3-5 layer set up on the line.

Q:I have an electrical box with 3 on off switches in it, 1 comes in from a ceiling light (it will be the only switch for it), the second will run to another separate ceiling light and also continue to another switch, and the third will run to an outlet which I want to be able to turn off and on with the switch for a table lamp.Starting at the power source coming into the box how should the rest be wired to work independentlyThanks

From the description of your plan I doubt that the whole scenario will be accomplished. First off, you say that the second switch will control a ceiling light which will also be controlled by a second switch at a remote location. It doesn't sound to me from the way you're talking about this setup that you've allowed for the fact that you're going to need two 3 way switches to operate the ceiling light, and which require a third wire for operation. So, if you think that over for awhile and come back with a different idea then we can probably help. This setup isn't going to fly the way it is.

Q:Whether the wire tube is connected to the electrical bridge can be connected to the bottom of the bridge

RVVP2 * 0.75 * 10 is the communication line is a kind of power cable shielded wire, 0.75 square line

Q:First time soldering, I guess wires got too hot or I touched it with the soldering iron and the ends are now melted a bit. I put the heat shrink wrap over top the splice spot. Think they'll be alright?

They'll be fine. In the future just remember to heat the wire and then touch the solder to the bare wire allowing it to flow and cool to a nice, shiny solder joint. Always be sure and use a 60/40 solder with a flux core for electrical work.

Q:What is the difference between RVS and RYS wires?

ZR indicates flame retardant. KVV PVC insulated control cable Uses: electrical, instrumentation, power distribution device signal transmission, control, measurement. KVVP: PVC sheathed shielded cable Use: electrical, instrumentation, power distribution device signal transmission, control, measurement. RVV (227IEC52 / 53) PVC insulated flexible cable Uses: household appliances, small power tools, instrumentation and power lighting.

Q:I live in a building that was built in 1928. Much of the original wire is still in use, Recently, I tried to install a new ceiling fixture but the wire was so old that when I touched the cloth insulation some of it literally turned to dust. (As a result, I called an electrician to replace the wire and install the light.) In the early 1970s, the building was upgraded with circuit breakers and some new wire, but does the old wire need to be replaced? Is it a fire hazard?

As a general rule, old wiring does not need to be replaced until it is modified, added to or otherwise becomes a hazard. There are, in fact, many houses that have the original wiring from the early days, still in use. Most civilized places, however, have chosen to upgrade/remodel, meaning the old stuff was removed, either as fixtures wore out or perhaps when any new building permit was requested.

Q:My instant electric water heater is 4500 watts need to use the number of square wire electrician said 4 square wire can I see a lot of people say that the 6 square of the job Will you 4 square line can withstand it? Question added: how can we know that the line is the national standard or non-national standard ah line is the original developers to help me installed a 4 square does not know is not how to identify the national standard?

Halo. I do this line do not ask me also ran here to ask .. no problem .. it is best to use the best iron soldering .. no welding does not matter. Effect is not bad!
