2. Product Working Conditions

(1) The Maximum rated working temperature of the cable conductor is 90 °C.

(2) The Maximum temperature of the cable conductor is 250°C, when it is short-circuited( the longest duration time is 5s)

(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.

(5) The cable drum should be attached with the packaging signs prescribed in 8.4 and indicate its right rotation direction.

4. Transport and Storage

The cables should adjust to all the transport means including the water, land and air transport. In the process of transport and storage, great attention should be paid to:

(1) Preventing moisture from entering into the cable.

(2) Preventing severe bending and other mechanical damages.

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

Q: The name of the plastic rope of the wire when the computer is installed: You better do not change! The Because the line if the wrong will really burn the motherboard or USB device! The Is it not a 5m USB extension cord? You can buy one! The Or with two 3-meter pick up! It can be! The Too long a USB cable will affect the signal transmission! I suggest you do not exceed 5 meters (5 meters has been very metamorphosis)! The hope this helps! The The

Q: I have 4 consecutive 110v outlets that are only receiving 82v and the receptacles are not working. I tested them with a multimeter. I tested from both the receptacle and the wiring to the receptacle. What do i need to do to resolve this. The breaker isnt tripped, and the fuses are good. I have checked switches- to see if maybe one needs to remain on for the string of outlets to work, but there doesnt seem to be one tied into them. it is 4 outlets on one side of the living room. no gfi to reset. the house was built in the mid -90's. as far as i know-- there has been no hack job engineering done before i moved in. i bought the place from original owner, and they said its original wiring. any suggestions would be greatly appreciated: Check the power at the breaker and make sure you are getting 110 there.

Q: The total power of six kilowatts need to install the number of square wires: Is not reserved. But must pay attention to the truth of the cold up and down.

Q: I am putting in a RV pad and I need a 30amp electrical service what Gage of wire do I need it will be aprox 200' run maybe a little less: Well I can only comment from the UK regulations. A 30A supply over a 75 metre run would need a large cable as the voltage drop due to the cable resistance would be high, and as you are using 120V you can't afford to loose too many volts through resistance. I would use a 16mm square cable, that has a core (copper) diameter of around 1/4 or just less. I will let you convert that to AWG. I suspect you will also need a Ground Fault Interrupter on the circuit at the origin as it is an installation outside, use the standard 120 volt couplings that you normally use with your RV supply.

Q: electrical wire: i would say around 30 amps would be the maxing level lastnthebest88 Hes talking about AMps the power unit not the car amplifier

Q: Describe how the electrical resistance of a wire changes as the wire becomes longer. How does the resistance change as the wires becomes thicker?: The resistance of a wire is directly proportional to length.

Q: I love to watch home remodeling shows with my boyfriend (who's an electrician), and we can't help bursting out laughing when people screw up electrical wiring. They think they know what they're doing, but they really don't. I saw one episode where they were trying to remodel their kitchen, and spent 5 minutes just trying to turn off the power. Then they go and cut through a live wire from a different circuit! Do you find this hilarious too?: I bet the cannibalistic chefs are interested.

Q: I am adding a new electrical outlet and need to know how many volts the electrical wire needs to be rated for. I will be running the new outlet from an existing outlet This existing outlet uses a wire that reads Type NM-B WITN Ground 600 Volts. Does this mean the wire from the existing outlet to new outlet also has to be 600 Volts? I have a 120 Volt laying around but it doesn't sound like I should use that one. Am I right? Thanks!: Use #12 wire. Most outlets in a home are wired to a 20 amp breaker and this is the correct wire size. 14 gauge wire is used for lighting circuits.

Q: I have a back patio light that is obsolete now that I added a covered porch. Could I add an electrical box, attach additional wiring, run it through conduit and ultimately attach it to a ceiling fan in the overhead patio area? (from the point from where the wiring attaches to the original light): Yes it is , but do not hide the box. you must be able to see and open all boxs after the the job is done.

Q: I want to know, which type and size of wire we use for different household appliances in a home ?for e.g: if we want to connect a full size refrigerator/deep freezer/air-conditioner then which type and size of electrical wire we use ?if we have an electrical switch board that has 6 switches and 2 sockets then what type size of wire should be used so that there would be good connection and to avoid burning or heating of the wire and hence the appliance ?thanks a lot for your co-operation: The average home uses # 12 wire. Older knob and tube homes use # 14. If the refrigerator is on its own circuit, # 14 is plenty. Lok at the appliance rating: Watts Volts X amps. A 1200 watt appliance at 120 volts would be 10 amps. A # 14 wire is fused at 15 amps. A # 12 wire is fused at 20 amps.
