Q: My home meter access line only 1.5 square copper heart line, is available? Because air conditioning only sleep at night when the open, the other only the refrigerator and 40W lights. Other electrical appliances do not open when sleeping. Thank you! More: 1.. of course, a little tension, and now the general air conditioning is a separate line, 1.5 is the standard lighting line, an air conditioner at the start of the current is certainly more than 1.5 of the safety range, and should be able to apply for expansion of the power supply

Q: 5000W of electrical appliances, how much wire to use? 220V: For example: 1000 watts of light to how much wire ah? I want to install a basketball court stadium lights, 4 × 1000 watts, the line is to walk around, each lamp a switch, FireWire with 4 square copper, zero line four common, is 4 square copper, I do not know Is it possible? What is the price of copper? According to my line to the line of the budget about how much? (The stadium around the 30m × 18m this problem is divided into two cases: the principle of power supply: the distance from the long calculation of the pressure drop, the distance from the short diameter of the wire on the capacity to say that 1000W lights with 1.5 square lines on the line But you have to ensure that there is a voltage of not less than 200V on the target, which requires that the resistance of the wire be less than 20V / 5A = 4 ohms. If the long distance from the power supply, please tell the distance and requirements (with aluminum or copper), I give you a calculation. If the four lights, with three-phase electricity better, two of which Each phase of a lamp, the other phase with two lights, each lamp with 1.5 square feet, zero line with 1.5 square enough. We all know that with three-phase power line is it. If it is single-phase power supply, shared zero Line should be 6 square, this is the design requirements, you can use the amount of fine, no matter what.

Q: Hello.I switched over from a gas dryer to an electrical dryer in our home. I ran 10/3 wire from a dp 30A breaker to a 4-wire recaptacle for the dryer.When I turn on the dryer, she spins but no heat.When I checked the outlet, each hot wire to neutral gets 120 volts but between the two hot wires I do not get 240. I then went to the breaker and checked there. Once again 120 from each of the hot wires to neutral, but no 240 volt reading from one hot wire to another. What would be the problem?In fact, when I check any two hot wires on the breaker I do not get 240 volts. Why? I tried swapping out the 30 amp breaker for another one in the event that it was faulty, but alas, still no 240 volts.: You need two breakers for 240.

Q: How do i wire two lights on a 3-way switchi have been messing around with this forever. If you have any web links to diagrams or can word it out that would be greatthanks: This is one of the easiest of the intermediate wiring circuits to do.To start, you must identify the power wire and it's neutral (white), then connect the neutral wire to the lights. Connect the black lead from each light together and to the common of one of the switches. Connect the other 2 terminals of the switches to each of the wires that connect to the other switch, Now connect the hot wire to the common terminal on the last switch. If you use a white wire for a power lead, you should mark it with a piece of black tape around the insulation. One of the other responders has a very good link that shows just how it should be done.

Q: What is the role of the wire of the two-color line `` `` ``: And now quickly put the PVC pipe into the also too late! It's dangerous to use it later! Suggestions to improve now! Or remove the sub-board from the new board! Will not damage the material! Please be careful!

Q: How can I run electrical wire 2700 ft without signifigant voltage drop only 110 volts: Use the largest gauge wire you can afford.

Q: Every few months between 2am - 5am we are awaken to a electrical/fire burning smell. It only last about a minute and then it starts fading. We get up trying to locate it but with it only lasting a minute we can't pin point it. We unplug everything and smell all the electrical outlets and there is nothing. What else should we try?: Check your refrigerator, may be the defrost system malfunctioning. Check your outlets for problems. Smell all appliances when this happens. Check your wiring if it is up to code. Last thing you need is to have a fire

Q: i have a basement stairwell with one light at the bottom, switch at the top. I want to make it a 3-way switch with 2 lights. 2 sections lit from either top or bottom of stairs.How to do? the wiring dates from 1954, but there is plenty of amperage left on the fuse formula. Thanks ahead of time.: Hmmmmmmmmm 1954. Is it in pipe or romex or BX(armor cable?) If in pipe, it is most probably cloth and rubber covering. High flamable and very smoky when burned. The more you move it around , the greater the risk of shorting. If you really want to try then use two wires of the same color for runners between the switches, and one wire for hot. take these to the junction you have for the new switch and install. Obviously the odd color goes on the odd color screw. The first switch should be connected with the runners on the same color screws and the wire to the light goes on the odd color. Oh yea, before you start, have a fire extinguisher and an ambulance nearby. Just kidding.

Q: I want to know, which type and size of wire we use for different household appliances in a home ?for e.g: if we want to connect a full size refrigerator/deep freezer/air-conditioner then which type and size of electrical wire we use ?if we have an electrical switch board that has 6 switches and 2 sockets then what type size of wire should be used so that there would be good connection and to avoid burning or heating of the wire and hence the appliance ?thanks a lot for your co-operation: House wiring must conform to wiring codes. Some places require the work be done by or at least signed off by a licensed electrician. Unless you follow your local codes you run the risk of fire, or even death in wiring near water. What's more, you will not be covered by insurance and you will be held personally responsible. There are too many opportunities for wrong answers on the internet. Please consult a licensed electrician.

Q: I have an electrical wire that fried on the outside meter box that leads to the inside. Who is responsible for that me or HOA?: the power company owns the wire that goes into the meter box from the street. They also own the meter and the box. You own the wire from the meter box to your service box. Kabish??
