Q: Can I run a ground wire from and electrical motor to a bolt that is screwed into wood? Will this work? I have a hot tub and replaced the motor, the new motor has the thick copper ground wire mounted on the back so the wire I have is too short now to reach to where it was grounded before. I ran the wire from the motor to a bolt that is screwed into the wood frame of the hot tub. The old ground went from the motor to the metal brain box witch is also attached to wood so I figured my alternative fix is OK?: Use a wirenut and more wire! It must be a good mechanical connection for grounding. No soldering either. It's not allowed. Tightening two wires together into a piece of wood is not a good mechanical connection. If the wood cracks or the screw becomes less than tight because the wood fibers get wet, the mechanical integrity of the life-saving ground connection could be compromised. Your homemade wooden terminal strip idea is unusable for grounding or any other purpose in home 120/240 volt electrical systems. You can/should tape a loose ground wire to the outside of the supply conductor conduit, for protection of the grounding conductor. I'm glad you asked, and the answer is an emphatic NO! p.s. The best thing would be a new, one piece grounding wire, from point A to point B. Use mechanically crimped eyelets on the wire. Use at least a 14 gauge piece of green colored, stranded, copper THHN wire, available at Home Depot, Lowes, etc by the foot.

Q: Is the WDZ-BYJF wire the same as the BV wire?: Are copper wire. BV is a PVC insulated wire, fixed laying, can be used for indoor application, wear the occasion, the conductor long-term allowable working temperature 70. BY is a polyethylene insulated wire, high insulation resistance, can be used for high frequency applications, the minimum use of ambient temperature is minus 60 degrees.

Q: Hello.I switched over from a gas dryer to an electrical dryer in our home. I ran 10/3 wire from a dp 30A breaker to a 4-wire recaptacle for the dryer.When I turn on the dryer, she spins but no heat.When I checked the outlet, each hot wire to neutral gets 120 volts but between the two hot wires I do not get 240. I then went to the breaker and checked there. Once again 120 from each of the hot wires to neutral, but no 240 volt reading from one hot wire to another. What would be the problem?In fact, when I check any two hot wires on the breaker I do not get 240 volts. Why? I tried swapping out the 30 amp breaker for another one in the event that it was faulty, but alas, still no 240 volts.: Check across the bus bar (where the breaker plugs in to the panel) see if it has 240 volts. This is the bar that the breaker plugs in to. If you do not have 240 volts across this then check the line side of the main breaker (where the wires terminate at) see if you have 240 volts across this. If you have 240 on the wires that attach to the main and do not have 240 across the bus bar you have a bad main breaker not giving you 240 volts. You may try to re set it and see if that does the trick. If you check the line side if the main and do not get 240 volts then you should cal an electrician Hope this helps

Q: I am installing a new light switch on the inside of an exterior wall in my walkout basement. Because of the floor joists and finished ceiling, the only way I can figure to get the wiring to that location is by punching it through to the outside and running it along the wall and over to the location of the switch. This run will be about 30ft long and go around one corner. My question is: Can I do this with bare UF (outdoor romex) wire? Or will the wire need to be installed in a conduit?: Wires above ground should be in a conduit to protect them from abrasion. Grey romex is okay for underground without a conduit, as long as it's buried at least 18 in the soil.

Q: I had a small infestation of mice in my garage a few years back. I noticed a hole under the breaker box that looks like it was from the mice. Is it likely that they chewed on the wiring or was this just an entry point? How would I know without tearing out the drywall or pulling all new wiring?: Do Mice Eat Electrical Wires

Q: How to identify the quality of the wire is good or bad!: You take the graphics card 6pin power supply, red are graphics cards, motherboard auxiliary power supply is black, 4pin or 4 +4 structure

Q: i have 4 dogs and they like to chew things like electrical wires and that could be very harm full to them can anyone tell me a cheep way to get them to stop? i don't want my baby's to get hurt and they are rewinding all my cords!: Bitter okorder

Q: I have a ceiling fan with a light fixture attached and I accidentally cut the wires that go from the light fixture to the ceiling fan. Now the light is completely off but the fan is fine. However, there are wires hanging from the fan that spark when the fan comes on. Can I just buy some wire caps and be done with it?? Thank you!: call electrician before you burn down youre house

Q: I have a lot of equipment in my local and I'm suffering about big cargo in electric wire for your knowledge voltage 220 Ventensity 30 Awire Demetre 2.5 mmwhat should I do for avoid the damaging of disgenctor or burning of wire: The wires too small for 30A! You need to upgrade the wire size or lower the amperage! The set-up you now have is just begging for a fire! Be Careful! ;-)

Q: I was in a room upstairs a few years ago (the one I'm in now) when i was about nine. I was hooking up N-64 or something and the wires started shaking. It wasn't a gentle shake though, it was a very violent shake. It seemed like there must have been someone back there shaking them, but of course there wasn't. Since then, I've been afraid of this room, especially at night when I have to turn the lights and computer off before I go to bed. I constantly feel like there's someone watching me. Does anyone have a reason why those wires were shaking that day? Do you think it could have been some type of paranormal activity, or just an electrical problem?: Spirits can be attracted to, or trapped by electrical wiring; my partner helped a friend who was having problems with a ghost in his house, and the problem centred around a bunch of wires and junction boxes under a staircase. he had an electrician come in and sort out the electrical problem, and the ghost problem was solved as well. In William Monroe's books on astral projection, you are warned NOT to approach power towers or other high-voltage sources in your astral body, because one's astral body may be 'trapped by the electromagnetic field. It is theoretically possible that entities may also be 'trapped in such a field caused by faulty wiring, or else they might draw on it as a source of energy. It is certainly NOT impossible that you have a ghost' in your room; but if the only evidence you have had thus far of its presence is a few shaking wires, then it's probably nothing you need worry about.
