- Q: The power company are doing some work on our road. and are going to be moving the terminal thing on the side of our house (2nd floor side wall) where the electric comes to the house and feeds both ours and next door (semi-detached). We have seen some dwellings that have a long UPVC bright orange plastic pipe covering the cable for a few meters and wondered why they do this?
- It is to protect the cable and people and animals. It stops animals chewing and protects in case of hitting the cable.
- Q: I am building my first computer and i was going to order a 750GB HDD to back up a 60GB SSD but it is a bare drive. Are there any cables/cords/connectors that i need to buy or should they all come with the motherboard?
- Most motherboards come with1 or 2 SATA cables. Keep in mind that this may not always be true.
- Q: i have a 600w rms and a 300w rms amp the 600w amp has an 80a fuse and the 300w has two 25a fuses right now i have two seperate power cable for each amp going to the battery the inline fuse for the 600w amp is 100a and the inline fuse for the 300w amp is 50a (i need to swich to a 60a i know) they both have 8awg power cables 100a amps is about all a n 8 awg can handle so what i want to do is run a single zero guage cable to the firewall than on the inside of the vehicle have a distribution block what i need to know is -what guage wire should i use for the power wire at the battery-what size fuses to use and how many-the locations i should put the fusesthanks i pick best answers fast
- i would use 4ga. wire at the battery with a 120 curcuit breaker about 12-18 inches from the batery then 6-8 gauge off the dist.box to the amps
- Q: I have lost the power cable which came with my computer's PSU and after looking online for a while the online shops seem to sell the power cables with little information about whether or not they will function with different PSUs so I am guessing it doesn't matter which one I buy.
- They are not special just a kettle lead really and should cost less than $5 as said if it fit it is good, look around you probably have one lying around
- Q: computer MB does not contain a power supply connector for the SATA power cable leading to the SATA HD, is this the norm? the cable connector is 5 prong female, there is no 5 prong male connector on the MB or the PSU. any suggestions?
- The power for your hard drive actually comes from your PSU, in the form of a 4-pin molex connector. As for the SATA...if it is a SATA hard drive, you'll want a SATA motherboard. Almost all modern motherboards have these connections. If yours doesn't, I'd imagine it's just old...or really cheap.
- Q: Hi, Whether it will causes any problem the power and speaker in a same path? I dont have a separate path for speakers to mount it in wall. I plan to use the existing path which is used for other electrical items. If i use the same path for electrical wire and speaker wire, it will damage the speaker or will make any short circuit in the electrical line?Thank you.
- You will be fine. Keep in mind that both cables are insulated. You are not going to get a short circuit. I have my speaker wires running next to the electrical cable in several of the rooms in my home and have no issue at all. Hope this will help you out.
- Q: I have a feeling my power quot;brickis faulty and need to find a replacement, hopwever, none of the high street retailers quot;Game, Gamestation, HMV, Argosseem to stock them.
- u can contact microsoft talk to them on teh phone for 5-10mins and theyll giv u a free one
- Q: I used my laptop as a home computer, most of the time I keep my laptop turned on with the power cable plugged in. Is it good to do that? or is it better to plug the power off whenever the laptop's battery is full? Which one is good for my laptop' maintenance? By the way, everytime I asked this question, people give different answers. So I really need a professional opinion.
- Ok, straight to the point, keep it plugged. Besides losing the power over the time you have it unplugged, most laptops are equipped with a power saving feature that reduces it's power consumption. This means that the PC will have to use less for processing which in turn reduces your PC's speed. To check this out, try booting your Laptop with plug on. When you see the desktop, look for the my computer icon on the desktop or on the start menu. Right-click on it and select properties. Look for some number preceding Ghz and remember it. now, unplug the power cord from the laptop and restart the PC. do the same thing when you see the desktop after the restart. notice that the number you had the last time decreased. (if it did not decrease, then it means your laptop still operates at the same speed when unplugged and will be fine when unplugged) besides the speed reduction when unplugged, the screen will be dimmer when unplugged. also, when the batteries are full, they are not charging when the plug is still on the laptop. the laptop will use AC power when it knows that the batteries are full and it's plugged in.
- Q: When I plug in my xbox that wire with the box on it has a red light instead of a green and ocassionally it turns yellow and my xbox wont turn on how do I fix this
- Disconnect each and everything except for the wires behind television and likewise get rid of xbox 360 confusing force and insert back connect each and everything back in position. the project must be fastened If difficulty nonetheless keeps happening then its an illustration of having a clean ability adapter(cable container) For any more desirable questions about xbox 360 be at liberty to ask
- Q: (for example : 1sqmm, 4sqmm, 35 sqmm) i need a formula to calculate current by knowing the area of the cable?
- This is not a simple answer. The amount of current that a cable can carry depends on the amount of voltage drop that you can tolerate (mostly an issue in long cables) and the temperature rating of the insulation used on the cable ( the higher the temperature rating, the higher the current that you can run in the cable) and the ability of the cable to loose the heat that is generated from the I^2R drop in the cable. For example, if a cable is in open air with no other heat sources near it, it can accomodate more current before compromising the insulation. If a cable is in a conduit with other cables that are generating heat, then the conductor needs to be increased in size to decrease the heat. The ampacity of the cable is also affected by the duty cycle of the current that the wire is carrying. If the duty cycle of the current is 10% then the wire can carry much more current compared to a current of 100% or continuous. Having said all this, there are tables of ampacities for various sized wires.
