Q:I have a single closet light that I need to extend about 3 feet. I've already bought the junction boxes, wire nuts, and wire retaining pins.However, I bought 14/2 wire, and I've noticed the wire I plan to extend says 12/2 on it. Is this a problem? Should I return it and get 12/2 so it matches exactly, or will it work okay? What's the difference anyway?Thanks: For a fixed load and less than 6 feet it would meet NEC in the past. I'm not certain about the current code. As to would it be OK the 14/2 wire is rated for 15 amps and unless a short develops in it I would not hesitate to do that in my home.

Q:explain to me with drawings 'n steps to take: In the U.S., you will likely need a professional (electrical) engineer to do any plans. He will likely be working with similar mechanical and plumbing people, and the architect. His work will also be affected by local codes and standards. Get the preliminary plans from the architect. Get size of building and estimate volts and amps needed. Confirm with local utility and tell HVAC people (mechanical engineers) so they can pick out systems that use the voltage. Figure out how much floor space you can cover with a 200A panel (or whatever size you plan to use). Put panels in the middle of each space that large. Add outlets, switches, lighting, and feeds to HVAC. Put in a main distribution panel to feed the sub-panels and check for breaker sizes, wire sizes, etc. Draw a 'panel diagram'. Check the final mechanical equipment schedule to be sure voltages and power use all match. Get the EE to stamp and seal. Deliver drawings.

Q:Cable model ZB and ZR What is the difference: Cable trough, generally the material of this PVC trough, the width of not more than 80mm, height of not more than 50mm, suitable for the layout of a small number of cables, wires

Q:As we know the earth wire takes no current or just a small amount of leakages current, why we should use same size as live or neutral wire in a power system??: Rule of thumb is that the earth wire should be half the csa of the phase conductor. This ensures that it can carry the maximum fault current that could occur at that point for sufficient time for the protective device to operate.

Q:Wire in the blue line, green yellow line, gray line on behalf of what does this mean?: AV cable can be connected to the set-top box is not only two-way port? If the signal is not good to persuade you to buy a adapter,

Q:I am wiring a new screened-in porch, and i need to run wires to a switch box through conduit. I plan to run conduit from the basement out to the box and then into the ceiling, where i will then change the wire into reqular Romex when it is in the enclosed ceiling. I need to know how many wires will fit in the conduit. I was planning on using 1 inch conduit from and to the switch box. I am using 14-2 wire through a 1 conduit. thanks: wHalf inch conduit is fine. Rather than try bending the conduit, you could run straight to lengths to ells with covers. The wire will push for a considerable distance through straight runs. If a ground connection is available at the point from which you take power, it would be best to run a green ground wire in the conduit, and use Romex with a ground. Also you might consider using number 12 wire all the Way, if you are connecting to a 20 amp breaker or fuse. That way you could put a receptacle out there too.

Q:i know both of them are great conductors for electricity, but why is copper better and/or safer?: The crystalline structure of copper is more suited to distribute electrons between cells. This means lower resistance to the current flow which means less lost energy in the power lines. Flip side: Aluminum is better than copper because it is much cheaper and lighter weight. Aluminum is usually used in high voltage lines.

Q:Hello,I'm attaching a 12/2 wire to a new light fixture. The fixture has the white, black, and bare wire. The 12/2 wire also has white, black and bare wire. I've connected them together using wire nuts and then electrical tape.But the instructions say this: Helpful Hint: Attach copper ground wire to grounded outlet box.What does this mean? There was a screw that says ground on the light fixture. Do I need to attach the wire to this screw, PLUS connect the 2 bare wires together? Or can I just connect the bare wires together only?Background info: This house was built in 1998 if that helps. Also, this project is simply replacing the light fixture in a closet that I've moved about 3 feet. Just a standard light, nothing fancy.Thanks!: RE: How do I put wiring through a stud from an electrical outlet to a new light fixture? I've drilled a hole in the wall where I am installing a new light fixture, and pulled out the wiring from the outlet below, but there is a stud between the wiring and the new hole. What's the easiest way to send the wire to the new location? I don't have access to the wall in front of

Q:I will be installing spray in foam in the wall cavities and am wondering if I should have all of the wiring replaced (electrical outlets and the such) before. I've read it's difficult to replace wiring once the foam has become rigid. My fear is that a wire will short and the electrical outlet will become useless (due to previously stated problem). Any information is greatly appreciated.: unsure what an electric powered pen is, I decide to apply a multi-meter style gadget, that tests for continuity, AC or DC voltage and delivers the quantity of each and every. you're saying that there is a present day, yet no point out of how a lot. looks such as you have a returned feed from someplace in the circuit. the percentages are that the corridor and bedrooms are all on the comparable circuit, which should not be, yet in older properties it befell greater usually than it would, exceptionally if the home proprietor does the wiring. it is likewise obtainable that there is one or 2 shops that have unfastened or broken wires going to them. i've got seen it ensue greater advantageous than as quickly as, and on an identical time because it 's no longer relaxing looking it, it extremely is done. maximum suitable advice could be to get a qualified electrician in for a glance-see. it may well be somewhat easily worth the money. by technique of how, Stanley, i've got worked on hundreds of properties, electric powered systems, taught electric powered in 4-H for years, and have under no circumstances heard of retailers being under pressure in sequence. that could make no experience in any respect. shops are under pressure in paralell.

Q:--A wire of resistance 10 ohms is bent to form a circle. Calculate the resistance between two points at the end of the diameter.--I can't understand this. Please show me the steps for finding the answer. I will appreciate your help.: 5ohms, since it is now in parallel? Maybe?
