Q:can you use just one power (positive) cable cut it and use the rest for your negative

Wire is wire. The only difference is the insulation color. The biggest problem in using wire with the same color insulation is that it's really easy to get them reversed. And just one fraction of a second of reversed polarity and the amp power supply (maybe other things too) is fried. If you insist on using the same color, you should slip a short piece of shrink wrap onto the end of the negative wire close to the terminal so it can be readily identified.

Q:So I was trying to run wiring for a 220 outlet and I hit a lower leg with the metal cable snake, now a bunch of outlets loose power for a minute or two ever so often, 20 min give or take. What can be the cause? Only the top breaker tripped. How can this be repaired. Please help.

Would I be right in thinking you sort of tripped on flexible metal conduit in which electric cables run and now the power is intermittent and trips the breaker? I would start by isolating the circuit so it is no longer live and checking the connections at each end of the cable run because any strain on the conduit could have tugged wires out of their terminals. I'd make sure that all the connections were tight and the wires properly anchored and also that each wire is in the correct terminal. I once made a mistake when replacing a socket outlet because the terminals in the new one were the exact opposite of the old one. Luckily, I found it straight away when I tested the circuit. If the connections all look good, I'd check the continuity along each of the cables. It is inconceivable that the cables inside the metal conduit were damaged as they should be continuous cable runs with no joins. The continuity test will tell you if any cable is no longer continuous, but I'd be very surprised as long as the original installation was done properly to code (or wiring regulations in the UK). Obviously, before you start checking the cables, you would unplug or disconnect everything that is connected to them. If the fault only happens when some sort of machine or appliance is connected, then it suggests the fault is with the appliance or machine and not the wiring. A 20 minute cycle of faults makes we wonder whether there is a fridge or a freezer connected the circuit. If so, I'd get it checked for faults and check that the power connection to it is correctly wired. I am not an electrician, just an experienced home owner, so please double check anything I've said. Good luck.

Q:Hey,I left my PS3 in the living room, and I think the dog peed up it. Stupid place to leave it, I know. Anyway, I brought it back upstairs, hooked it up but when I went to plug the power cable in, there was a real loud buzzing sound coming from the PS3, right where the cable goes in. When I unplug it from the PS3, it stops. I tried leaving it to dry, and making sure there was no moisture present inside the machine, but I tried hooking it up again and got an electric shock up my arm from it.Should I buy a new cable, leave it to dry, or is there something inherently wrong with the PS3 now?Thanks :)

Ive never come across this before. Maybe its because i don't no anyone who has a dog which has peed up there PS3. I would suggest you dont get a other cable because that one might break aswell due to water getting in your ps3. If i was you i would contact Playstation or the store you got it from for more advice. Like i say im not sure and i dont think many people will come across this problem.

Q:Whether the weight of the power cable per meter is calculated

AC power is a two-phase exchange of the power system, itself is positive and negative exchange, the electromagnetic effect can almost count the daily life of the free radiation are more than this number, and can rest assured that the general life supplies, the larger electromagnetic radiation from the DC Of electrical supplies, which only need to pay more attention

Q:I installed a 40mm fan on the GPU heatsink that is drawing power from the 12v on the DVD power cable. I'm also thinking of installing a couple 4'' cold cathode lights. How much power can you draw from the 12v DVD power cable before it becomes unstable?

its not smart to attach anything to your 12v power on the dvd line it can cause problems to your 360 and your dvd drive. get your 12v directly from the power socket .

Q:If so, where will i have to go to get it?

if the power cable is the same as the one on your computer, yes. If not, you may need to order one. However, you will need to take it apart to install it. Could be the power supply if the cord is not a removable cord.

Q:My power cord for my computer and all usb cables i have seen have these cylindrical things on them. What do they do?

Those devices are for supressing RF interference to external devices. The high data rates, tend to create signals just like transmitters, which can interfere, with you TV, cordless phone, stereo system, etc.

Q:power supply, however it comes with some cables that can be attached to the peripheral 4 point cable then ran into the card itself. can this setup work? Or will I need a new power supply with 2 6 point pci express power cables? Oh by the way its a 600 watt power supply I currently have.

i think you should be ok

Q:when sending off an xbox, do I include the power cables in the box?

dont send anything but the xbox! take out the hard drive all memory cards wireless and all wires before you send it back if you send anything else to microsoft they will not send it back they only send you back an xbox without a hard drive and a month of free xbox live no matter what you send them.

Q:I have a Dell Optiplex 790 SFF, I need a replacement power cable, on the manual it says for power: 240W, 1259 Btu/hr, 100 Vac to 240 vac, 50hz to 60 hz 3.6A. I contacted Dell and they said they have a power cable for it, the Dell 5120P cable which is 125 V 10A. Now my concern is with the 10A vs the 3.6A listed on the manual, should I be concerned?

no it will be fine, the maximum power needed as you state is 240W the replacement power cable is 125V 10A=1.25Kw so the power cable is grossly overated HTH David
