- Q: Hi. I was snaking 40 feet of underground burial power cable thru a PVC conduit. As I did not have any cable pulling lubricant, I used JOY dishwashing liquid detergent as a lube for pulling the cable with a snake. Will that damage or detiorate the outer jacket of the cable it is still in the conduit. The flexible conduit I used is water tight and I have plugged both openings with silicine caulk.
- It'll be ok for about 5 years. The chemicals will eat through the outer casing which is more resilient than the inner insulation. Next time, go to Lowe's, Home Depot and purchase some Wire-pulling lubricant.
- Q: The difference between the power cable YJY22 and YJY23 is in the outermost layer, one for the PE sheathed, one for the PVC sheathed. What is the applicable environment, and why? Question added: I have to ask is the difference between 22 and . not 22 and 32! Thank you for the answer. Learn more together
- 35 square copper wire current carrying capacity is 105A, 105A / 35 mm2 = 3A, (1 square millimeter carrying capacity is 3A) 70 square copper wire current carrying capacity is 169A, 169A / 70 square millimeters = 24A (1 square millimeter carrying capacity is 24A) 1 square hai load current from 11A gradually become 24A So it is impossible to use n by the coefficient can be drawn to the current value Wire can carry the current * the applied voltage * power factor = can drive power The diameter of the wire with different diameter is not the same No specific diameter can not know the current carrying capacity How much power, depending on the voltage level Because P = UI As the saying goes: a square 4 current, underground than this small forget How much is the square here is a square millimeter Power depends on your voltage, the general small line can be directly by 5 is to eat the current to 50-120 the basic can take more than 35 can take 25 or so just personal experience to do reference to the need for basic data: 1 line, copper and iron Aluminum silver temperature 3 core number 4 diameter Probably take a square 5A diameter n square of the wire can be over n high current, resulting in n high power so that can be calculated
- Q: I have plugged my old laptop power cable into my USB hard drive, and now it does not work at all. Have I completed fried the circuits? Is there any way to get the data back if I have please?Thanks for any advice you can offer.
- what you could do is, try and get another hard drive box and try the hard drive on that. If it is completely fried, you could get your data but data recovery is costly coz they have to physically retrieve the data. It could cost anywhere around 300$ - 1000$.
- Q: It's provided to me by my ISP which is Cox. If I were to unplug the power cord what would happen, would my phone no longer work without another technicians appointment. I know that the motorola cable modem with no phone service you can power cycle that one.
- With my Cable company it's the first thing you do (or the first thing tech support tells you to do) when there is any problem. It is set up to restart after power failures and brownouts, so I would say go ahead. If the phone doesn't work after you power cycle, Power cycle again and see if that time works.
- Q: Hi! I want to buy I new Hard Drive but I've got a problem. I have the IDE conector but I don't have the Power Cable. It is connected to my Video Card. Can I add a new one? Can I use a power cable from a optical drive(CD/DVD)? Thanks!
- All you need to do is pop down to your local computer store and get a power splitter, just make sure you get the right type, IDE and SATA drives have a different kind of power connector, so just make 100% sure before you buy!
- Q: Its on power and one is in a pc monitor and one is lying on the ground. Will the electricity go through the cable that is not connected and lying on the ground? is this safe to touch with hands or shoes?
- The voltages and amperages going through the Monitor Cables are too low to be of any concern. If you actually stuck your tongue into a live one you'll get a jolt that may be painful...but it's not going to kill you. Touching it with your fingers won't do anything. However it might not be a bad idea to cover it with a little electrician's tape (don't go crazy) to keep it from picking up anything that could jam or bend the pins.
- Q: And will it damage the PS2 it if I use it?
- Google the voltage the PS2 used, and if the PS3's power cable voltage is the same as the PS2's power cable then it's all good. Hope that helps.
- Q: Hey and just to start off with, your answer will be deeply appreciated, thanks..... Its about my PS3, when I was flying to Lebanon (which I am in now) my PS3 power cable got taken and thrown away by the airport officials the second time my bag was scanned.....so now I can't play any games because of this, it sucks goat balls, I know but my question is.... Where can I find another power cable..... P.S, my console was bought in Canada so the voltage was 120v I think but it was misbehaving when I used it with the converter I bought so I tried using without it and it worked like a charm on 240v, if that helps.... if there are any details I have missed out, my e-mail address is .uk
- that sucks!!! and weird, when i was boarding a plane, they kept all my stuff, but they did check it.... the best thing you should do, is buy a new one from online and let it go to your destination.
- Q: Our company needs a WELDING CABLE / DC POWER CABLE,50mm fine strand and color blue. Does anyone knows where to buy here in the Philippines? or if you know some suppliers, manufacturers please do let me know. It would help a lot. Thanks
- You can buy it from okorder
- Q: Do all power supplies 450 watt(or above)have the 12v 4 pin?
- Almost all current motherboards power their CPU with a 12 volt CPU power cable. There are two kinds: the 4 pin 12V cable and the 8 pin 12V cable. The 4 pin cable is often called a P4 cable (although it's a very bad name) and the 8 pin cable is called an EPS12V cable. The P4 cable is the most common. You should find it on 90% of power supplies you buy on the market, regardless of how many watts they have. Some power supplies have both the 4pin and 8 pin cables for redundancy. ~~~ All modern power supplies nowadays have 4 pin CPU power cables. They come as a standard. The 24 pin ATX power supply is also quite common, it's kind of hard to get one that's 20 pin nowadays.
