What size wire do you need for 100 amp service if you use alunimum?
2AWG.
How many amps will 2Awg wire carry?
CEC - #2 copper, RW90 insulation, 120 amps. #2 aluminium, RW90 insulation, 95 amps. he is not talking about Amplifiers. he is talking about amperes, the unit of measure that indicates how much electricity can flow through a wire. and it depends on the length of the wire, but 2 gauge wire will handle about 208 amps. depends on how big the amps are
Can a 200A 240V house panel be fed by number 2 conductors from a service entrance meter panel with 200A main breaker?
No, number 2 conductors are not sufficient to carry 200A. You would need larger gauge wires to safely handle that amount of current. It is important to match the wire size to the amperage rating of the panel to prevent overheating and potential hazards.
What size wire do you need for 50 amp sub panel about 200 feet away?
Well, honey, for a 50 amp sub panel 200 feet away, you're gonna need a 6-gauge wire. Anything smaller and you'll be playing with fire, and not in a fun way. So do yourself a favor and splurge on that thicker wire to avoid any potential disasters down the line.
How many amps in a 220 volt 10000 watts?
Not smaller than 3 AWG copper, or not smaller than 1 AWG aluminum. If this is a longer run (say to an out-building) than you need to consider line losses and go with a larger wire size.>>>>>>There is more to the question than meets the eye. Is this a 100A residential service that you are feeding with the wire in question? Is it a breaker for a sub-panel at a single family residence?If a Dwelling Service, according to NEC Table 310.15(B)(7), 4AWG copper or 2AWG aluminum is sufficient.If a sub-panel for a dwelling, you may be able to get by with the same, if the authority having jurisdiction (inspector) interprets this Table in that way.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
How do you install an amateur radio in a Nissan Pathfiner?
That depends on how you want to do it. Me, I upgraded the wiring from the battery positive to the alternator, battery negative to ground, and engine block to ground with 2AWG wire - if you plan on using an amp or any other device which draws a lot of electrical current, you want to do this, because the stock wiring is typically intended only for the stock electrical system, and the thin wire (6AWG - 8AWG) typically used for this has too much resistance to increase the electrical draw without the risk of it catching fire. Once you've done that, how you want to proceed is up to you. If you have an empty slot in your fuse panel, you can use that (although I would recommend you not wire in a linear amp this way, unless you like the idea of frying your ECM). A better way to do it... once I upgraded my wiring, I ran some 4AWG from the battery positive to a fuse panel I bought made by Blue Sea Systems. Then I ran additional electrical and electronic devices off of that. Of course, if you're not drawing too much power, you could simply use a cord which plugs into the cigarette lighter, if you should so wish.
How can you get electrical code answers?
AnswerAsk the question here and check the box for House and Home; Home Improvement; Home Electricityand watch for the answer inhttp://wiki.answers.com/Q/FAQ/1829You should also consult a qualified electrician, especially if you are going to do actual electrical work (as opposed to answering a test or homework question).Interpreting the code is not trivial. To add to the problem, answers you get here are based on the standard NEC, but municipalities don't always adopt the code as-is. Many adopt the NEC with ammendments, and these carry the force of law in that jurisdiction.For instance, suppose you ask "What size wire do I need for a 100 amp service to a mobile-home? Someone here might answer "#4 copper" which is right out of the book. But you live in Podunk, USA, and when they adopted the code, they ammended it to read " 100 amp service conductors for mobile homes shall be no smaller than #2AWG copper" (I just made that up, only as an example). The wiki answerers would almost certainly not know about your local ammendments, but a qualified electrician in your area would. It could save you a bunch of money and a lot of grief to get a pro to check your design to be sure it mets code, and worst-case could save a life.
