Q:Can we install control cable and power cable in one conduit?
it fairly is a huge-unfold prepare...to run ability and administration cables in diverse conduit however the uncomplicated standards is voltage gradings.All cables upto 500volts may well be laid in a single conduit whether ability or conrol.In case of extreme voltage cables, with the aid of fact of elecromagnetic inducion result, diverse conduit is accompanied.
Q:do all 1 tera hdd come with a power cable?
They should. I mean it would be dumb if they did not. But radio shacks or office depot type places. Like electronic stores or office stores. Online would be the best place. Just type the type of power cord your looking for on OKorder and I know for a fact you will find one. Good luck
Q:Should TRS or TS cables be used for the powered signal in a 2 channel PA?
very interesting question
Q:HP Printer Power Cable Identification?
What is the model number of your HP printer? Is it the C3180? I am looking for a power adapter for the C3180, and I believe the HP AC Adapter model number 0957-2178 is the correct one, but I'll find out for sure in a few days as I am ordering one. If you tell me the model number of your HP printer, I may be able to help you out because I have learned a lot about HP printer AC Adapters in the last few hours.
Q:What power cord and SATA cables go with this HDD?
You will need to buy a data transfer cable to connect to the hard drive at one end and onto your motherboard at the other end to carry data to and from the hard drive to your computer. The cable is simply called a SATA cable and they are about 18 inches long or so. They are usually either red, orange, blue or yellow in colour and they are about half an inch wide or so. You can buy them from your local computer store for about $ 4.00 or so Canadian. They do however come with your motherboard (you usually get two of them included in the box when you buy it). For the power end of it you will need to find an empty non-connected Molex connector coming from your power supply unit in the computer. Just simply connect this Molex power supply cable to the hard drive at the back of it where indicated. That is all there is to it. Good luck
Q:where can i get modular power supply cables?
the ability connectors that plug into the slots on a modular power supply at the instant are not conventional -- they're specific to that distinctive style of supply (there would be some standardization for modular PSUs made via a particular producer, yet i does not even be certain approximately that). So, in case you decide on extra cables, you will desire to touch client provider on your style of PSU or examine help boards at their internet site to work out what the technique is for paying for them.
Q:i need help on where to run my amp power cable from the battery to the amp on a 2006 f150 i cant find any?
steering rod boot or drill a hole
Q:Is it safe to plug in desktop PC power cables without an adapter?
It all comes down to the amount of output that the pc is set to take. I would think that you would be fine without the adapter, assuming it already works. If you do decide to do this make sure you set up a surge protector, dont just plug it into the wall. A power surge could fry the internals and brick the pc.
Q:What is the purpose of the small cylinder that is in the power cable near the computer connection?
It's called a choke. It's used to filter out unwanted radio interference.
Q:How is the best way to determine if a cable inside your computer is a data cable or a power cable?
You are correct. Power cables will always have 4 or more separated wires going into a plug. Data cables have all of their internal wires inside a single sheath.
