(3) The Minimum bending radius of the cable is 15 times of the diameter.

3. Packaging

(1) The cable drums for delivery should comply with the requirements of JB/T 8137.

(2) The coils of cable should be neatly wound on to the cable drums for delivery. The cable end should be tightly encapsulated.

(3) Only the cable of the same model and specifications is allowed to be wound on to one cable drum.

(4) The cables provided in rolls or bunches should be packaged in a proper way. The weight of every roll should not be more than 80kg.

(2) Preventing severe bending and other mechanical damages.

(3) Preventing high temperature and exposure to the sunlight.

Q:I am wiring a new screened-in porch, and i need to run wires to a switch box through conduit. I plan to run conduit from the basement out to the box and then into the ceiling, where i will then change the wire into reqular Romex when it is in the enclosed ceiling. I need to know how many wires will fit in the conduit. I was planning on using 1 inch conduit from and to the switch box. I am using 14-2 wire through a 1 conduit. thanks: 14/2 romex wire can not be ran through a conduit,unless the outer casing has been striped off.Usually a THHN type wire is run through the conduit to a junction box and then connected to romex wires.The chart in my code book shows a maximum of 39 number 14 THHN wires in a 1 conduit.This is a 1987 edition code book and I think the codes for this has changed so now you wouldn't be able to put in that many wires.I would guess that you are not going to pull that many circuits for it to be a problem though.

Q:i am used to the red, black, white, green and bare cables. but i got a chanelier with two black cables and a bare cable (ground) so how do i put it up?: Just hook up one of the black wires to your white wire out the ceiling, and the other black wire to the black wire from the ceiling

Q:(No I didn't do it.) I have a used vacuum and it has some damage to it's electrical cord by someone running over it several times. Some of the electrical wires are exposed but there is no damage to the wires, so it seems. What do you recommend other than replacing the vacuum? Thanks: yes, if the conductor is not exposed. Make sure to put a minimum of 2 layers of tape, more is safer.

Q:I have an antique home and I am trying to install a new ceilimg fan. The box only has a black and a white wire from the ceiling. I know where to connect the ceiling fan colored wires to - but to which do I put the ground to ?? Do I attach it to the black wire or the white wire??: Connect the ground to the box. Do not attach it to the white or black. If the fan is over a conductive floor I would be sure the fan is grounded. If over a wooden or carpet floor, it is not such a big deal. But per code, all metal parts must be bonded to ground. That is to save your life in case of a problem. If no ground is available you can feed it from a GFI protected circuit to meet code and be safe.

Q:I am replacing my old dishwasher which was hardwired but the problem is that the old wiring is just Hot, Neutral, and Bx cable therefore there is no reliable ground. THe new dishwasher comes with a 3 prong cable so i need to install a new outlet but my concern is the grounding. Some one please tell me what to do. can i get grounding from the nearest outlet which is about 4 fee above the one that im am trying to install.: If you use a metal clamp type connector in a metal box the outer casing of the BX will serve as a ground. Not to current code but if that is all that is available it will have to do. Use a continuity tester and see if you get a reading from the neutral to the casing. If so you have a ground path that you can use to ground the box. Then you install a ground wire to the back of the box and attach it to the receptacle. By code this receptacle should be a Single not duplex type. If not try the same thing at the other box. If you get a reading there fish a wire down to the new box. Other wise install a polarized 2 prong receptacle. Use copper pipe to connect the plumbing not plastic

Q:I have a light switch that is supposed to be attached to an outlet(the outlet is upside down), but when I turn the light switch on. It does not control the outlet. The outlet works and provides power regardless of what position the light switch is in. What should I do to fix this? I do not have money for an electrician!Does anyone know of any good self-help or do it yourself forums for electrical wiring type problems like this? I have very limited knowledge in electrical field but I am pretty handy with everything else.: This type of receptacle is referred to as a half hot. The outlet has a little gold tab on the hot side that bridges the two lugs that you wrap or stab the wire into. Typically this tab is broken and that seperates the two lugs and effectively the top and bottom of the outlet giving you the half hot. Either the top or bottom will always be hot and the other turned on via the switch. If this receptacle was changed out it could not have been wired properly or that brass gold looking tab was not broke off. Alternatively the switch could be disfunctional or bypassed to eliminate the switch all together making it a dummy switch with no purpose.

Q:I have a house built in 1960 that has what I think is original wiring. It is non-metallic sheathed cable. There are some places (underneath old leaks in the roof) where the outer plastic coating has disintegrated. Is this safe? Is there anything I can do to make it safer?: shell out and get the place inspected for sure. Is it safe? Sounds like it's not very safe. Unless your very hip and savvy or an electrician yourself, have a licensed electrician come and rewire the place. Safety is nothing to play with.

Q:i just want to ask a question.if you have to wire a house whether single phase or three phase wiring , then, would you choose a heavier wire for hot wire (live wire) or would you choose a heavier wire for the neutral ?3 - 29 or 7 - 44 . what size would you choose for neutral what for hot wire (live wire) ?thanks: Only a qualified electrician should wire a house. Any person could could just replace a switch or an outlet. Your POST is not a question.its a problem.

Q:I do children's clothing store, the front of the store in front of the right side of a wire pole, do not know because the store is not obvious or by the pole pole block, a lot of children's wear to go to the next children's clothing store, even come in and do not come to see, Most people come in after the first sentence is the original there is a children's clothing shop Yeah, said the wire pole to my financial road are blocked, so would like to ask how the feng shui master to resolve more: In the "construction site temporary electricity safety technical specifications" did not mention water and temporary electricity can not be together, you can press the cable straight to the practice (0.7m above and below the depth of 50mm fine sand backfill original soil, the upper cover Hard protection) to the construction, the appropriate widening of the cable trench, so that water and parallel lines. Wire and cable: wire and cable is the transmission of electrical energy, electrical signals and electromagnetic energy conversion to the wire products. Cables are usually made up of cable cores that transmit electrical or electrical signals and protective, insulated sheaths. A cable with only one cable core and a smaller diameter is often referred to as a wire. Also some wires do not have insulated sheaths, called bare wires. The cable in the cable is made of a metal material with good electrical conductivity, usually copper (good electrical conductivity) or aluminum (lower cost).

Q:What is the meaning of SC15WCCC to SCE in electrical drawings?: Do not recommend this access, if the computer accessories are more, such as multiple hard drives, discrete graphics, more than one memory, the need for more power supply, external speakers may cause the power can not give the host enough power, in serious cases Affect the drive, hard disk to read data, and even cause hard disk bad sectors, it is worth the candle. Serious suggestion not to do so.
