- Q: There is a group of 220V wire close to the walls of my house and live, and that side of the wall is just my bedroom bed, do not know for a long time will not cause harm to the human body? More
- Do not recommend such installation, hot water pipe hot air easily swallowed the cable, resulting in cable need to be repaired many times, even dangerous, according to "civil building electrical design specifications" JGJ / T16-92 is not recommended cable bridge laying in the heat pipe or corrosive Above the gas pipeline and the laying of the liquid pipe below, if you do not understand, you can see under the "civil building electrical design specifications", or the following article:

- 1. Check electrical wires and extension cords and appliances for wear and tear and faulty wiring. 2. Do not stick your fingers (or anything not meant to have electricity run through them) in sockets. 3. Keep electrical appliances clean and in good working order, and have them serviced regularly. 4.Never run cables under mats or carpets where you can not see wear and tear. 5. Never use water on class C or electrical fire.
- 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: Found a wire in my attic right by the hatch with about 2 of it burnt. I didn't see any bare wire exposed, but pretty close. It's not at a connection. There is a little bit of insulation singed around it.Maybe I nicked it when I climbed up there a few months ago? Maybe a squirrel or something was gnawing on it? I didn't see or smell anything dead.Or could it be it's just wired wrong?I'm pretty worried because it's connected to my smoke detectors that were wired last fall. I have 6 of them and they are all connected to their own separate breaker. So if it starts a fire and shorts them out I would never know.
- Call a qualified professional electrician to inspect your wiring make any needed repairs. You need to do this for your peace of mind. More than likely the burn is caused by an overload which is very dangerous and can cause a fatal house fire. Call an electrician now.
- Q: I believe that someone done this to be intentionally, and it did infact catch on fire. The two wire were spliced together and it lay across my heating vent. Mind you the wire laying across the heater never melted it was just off the heater were it caught afire. I was thinking that something was pasted or pored on the wire to make sure that it would catch, something like asatone or a paint product? Here are some of the numbers and letters that were on the wire AWM 2468 VW-1 60 degree 300V AWG24 H.W.G. C. Please and Thankyou Im just looking for answers.
- It's possible for the wires to catch fire if there was a bad connection. When you have a connection it gets warm naturallyIf the wires aren't connected correctly the wires can get hotter because of the way the electricity is traveling and catch on fire.
- Q: Bv4 square copper and BVR4 square copper wire What is the difference
- The former core is a single strand of hard copper wire, which is a multi-strand copper wire. 1), BV4 square wire GB diameter 2.22mm, BVR4 square wire GB diameter 19 0.50mm, 2), BV4 square wire with copper weight = 1.11 × 1.11 × 3.14 × 95 × 0.0089 = 3.27kgBVR4 square wire with copper Weight = 0.25 × 0.25 × 3.14 × 95 × 0.0089 × 19 (root) = 3.15kg3), the price BVR4 slightly higher point.
- Q: I'm 18 now, but when I was 15 (sophomore in HS), I did a lot of electrical wiring upgrades around my house. I changed the fuse box to a circuit breaker panel when I was 16. That same year, I did some wiring at my girlfriend's house (her dad let me). I installed a ceiling fan in her room and one in her parents' room.Do teen boys typically know how to do this? Or am I the exception?
- That's great you know how to do this but you better hope there's never a fire and it's traced back to unlicensed, amateur electrical work, or the insurance company will NOT pay for the fire damage even if the house burns to the ground. You seem to have the knack, so you really should get licensed if you want to make a career out of this. It certainly pays well.
- Q: i want to wire a single phase 230v 22amp air compressor will # 10 wire work or should i use #8 it is about 120 feet from main panel and what amp breaker should i use?
- With the distance you are from the power panel, it would not hurt the system to use the larger #8 wire and a #10 ground and the 30 amp breaker. The inrush current will be enough to lug the motor down when starting with a 10 wire. This will damage the motor over the long term.
- Q: I obviously know that one is one and one is the other, but if you were on the street and saw a utility pole. How could You distinguish one to the other?
- Power lines don't have insulation (the black plastic on the other wires) until it's getting attached to your house.
- Q: I am having a problem with the wiring in my basement. What I am doing: I wired a new outlet box off of an old outlet box. From the new outlet box, I then wired a switch for a new light fixture. So the wiring goes; fuse box, outlet box, outlet box, switch, light. Well, I blew the fuse once I turned the new light on. (BTW, I had a buddy stop at lowes to pick me up a switch and he returned with a 3-way switch). I only need it to operate as a 2-way which I have figured out how to do from the internet. My question is, while testing the outlet boxes and switch after I blew the fuse, I found the I have continuity between the common and hot wire. Mind you the fuse has been removed. So how can I have continuity between the common and hot wires? Thank you.
- With respect, you have mis-wired somewhere. Old Outlet Box is A New Outlet Box is B Switch Box is C Light is D A (hot)--------------------------- B (hot) ------------------------------------ C / --------------- D (hot) A (neutral/common)-------- B (neutral) ---------------------------------------- D (neutral) A (ground) -------------------- B (ground)------------------------------ C (ground)------- D (ground) As to a 3-way switch, in the switch box, the hot goes to the copper-colored screw, the leg to the light goes to either of the brass-colored screws. The neutral goes straight through the switch-box. Only the HOT gets switched. The ground is connected to all three new devices but is continuous. If this is not crystal-clear, call an electrician.
