Q:cable laid in the GI trays and temperature is 30 digree centigrade

There is no definite safe formulas for your cables because it depends on many factors like what conductor . what insulation, how many cores ,what is your load , where is your load and ambient temperature and so on. The best guidance will be from the particular manufacturer who would provide the tables under various conditions as above.

Q:if we provide power through power cable will there be need of extra capacitor near load?

Yes, if you are talking about a bypass capacitor. Electronics always requires a bypass capacitor near the circuit/IC. Having one at the end of a cable means the cable inductance is in series, and the impedance seen by the IC power supply leads is inductive and high instead of the needed low impedance that a local bypass cap provides.

Q:I have one Ethernet cable running to a WiFi antenna. The antenna is powered by the Ethernet cable, using PoE. I want to be able to plug the current cable into a hub or switch, so I can connect other devices (non PoE) like an Xbox 360 or PC, but I also need to maintain the PoE to the antenna. Taking the antenna off PoE is not an option. What kind of device can I use to split this PoE line into PoE and non PoE cables?

Well, most POE devices come with a POE injector which puts the power on the line. That box will have TWO ethernet connections one which goes to the antenna has power on it. The other is a DATA ONLY cable. (also connected will be the power supply) That data only is the cable that is connected to your computer! Put that to any switch etc it is just plain everyday ethernet!

Q:I'm curious, because I was looking through the 'combo deals' for a part for a potential build, and one of them was a SATA cable (item itself was a hard drive). Does Newegg, or for that matter any major computer retailer, sell products that come with all the cables you need to actually use the part? I guess I'm primarily concerned with Hard Drives and Disk Drives in this case... oh, and PSUs I guess. And the mobo, will that have the power cable?

Depending on what the combo contains, it may have the cables. - A power supply comes with a power cable for the outlet, and the usualy cables you find on a power supply... - A motherboard comes with 2 or 3 SATA cables, O/I shield, screws needed to mount ot case, manual, driver disk - JUST Hard Drives...well just the hard drive (NewEgg does not included any cables unless stated) - Graphics cards...adapters, manual, old drivers - Case: cables that connect to the motherboard (On/reset buttons, USB ports, Firewire, fans, sound/mic jacks) Hope this answers your question.

Q:I'm gonna be running a 2,700watts RMS system on a Power Acoustik 4,500watt Class D Monoblock amp at 1-ohm. I have a 2005 Impala LS do I'm going to need a secondary battery. What size should it be? Also what size power wire and ground wire should I use? I'm going to be using 8gauge speaker wire. Any help is appreciated. Thanks!

Q:I need to replace the power cable for my HF M300, but I'm having trouble finding the proper one. Can somebody tell me what it is I need (preferrably at OKorder)?Thanks!

The power adapter that came in the box is Canon's CA-570. Search for that at OKorder.

Q:I am thinking about buying a hard drive and a SATA to eSATA cable to get more space to store things but I dont know whether or not the eSATA cable supplies power to the hard drive like a USB port. Do I have to buy a power cable for the hard drive or will it work without one?

I use an external sata for backup with a usb cable converter the power comes from the usb cable, esata I suspect would be similar unless you are hooking it up with arj45 or something?

Q:I would like to buy a PS3 in america, but i'm living in Italy and I don't know if there is some problems because of the different voltage of the power cable, included in the PS3 box. I don't know if it's possible to buy the power cable separately...please answers as quick as possible10 point at the best !!!!lello è sexy

If you guys in Italy use the one that is a right side up version is this =D then you should be fine. If bot you can buy a replacement cable for like $20 at a game store or best but or something like that.

Q:I have a power cable for my computer that got slightly chewed and i was wondering does that effect the power.im just wanting to know if it will have less power or will it work the same and as far as i know none of the wires where hurt just the rubber around them.

It will work if the wires are undamaged. But they will have been kinked when the cable got chewed. The cable is now dangerous, if the wires are pinched you may get a hot spot, melt the insulation and fire/shock hazard. Turn it off and replace the cable.

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.
