Q:running wire to a pool motor, it is 1.5 hp, they pulled 10 guage wire and the breaker keeps tripping , do I need heavier wire?

Depending on the distance, heavier wire might help. It's possible that there is too much voltage drop in the wire during motor starting. That would lead to heavy startup currents being drawn for longer periods. The pump manufacturer should have wire size / distance recommendations. Voltage and current measurements at the pump during startup with min/max peak holding meters should reveal the problem. Don

Q:Consider a copper wire 1 mm in diameter providing the power needed to run an appliance drawing a 4.8 kW at 12 V. Assuming that no heat is radiated away from the wire while the current flows:A. What will the temperature of the wire be after the current has run for 1 second through the wire?B. What will the physical condition of the wire be at that time?(The wire was initially at 20 degrees C)

Battery's have their very own resistance (noted as their 'inner resistance'). the cost of the indoors resistance relies upon on the form of battery and its age. the full resistance of your circuit hence would be plenty greater effective than 0.064 ohm, so the present would be decrease than ninety 3.75A.. you will no longer get a electric marvel from 6V (although your tongue can detect it - no longer recommneded!). approximately 30mA around the guts can quit it. yet you may choose a plenty bigger voltage than 6V by way of resistance of the physique. in spite of the shown fact that there is achieveable of overheating the battery and/or the twine, which includes achieveable of hearth in some circumstances. Please do no longer attempt this with AC mains. There are severe detrimental aspects of deadly electric marvel and beginning a hearth. The kin risk-free practices equipment (fuse/circuit breaker/RCD) are meant to shrink the skill if the present is basically too severe or if there is an earth-leak - yet you are able to no longer possibility the risk-free practices of your self and others in this kind.

Q:A 5.07 m length of 2.1 mm diameter wire carries 703 mA current when 22.3 mV is applied to its ends. Determine the resistivity of the wire.

Resistance of a wire in Ω R = ρL/A ρ is resistivity of the material in Ω-m L is length in meters A is cross-sectional area in m? A = πr?, r is radius of wire in m Use current and voltage to determine resistance. Plug that into the above and solve for ρ. Be sure to change numbers into meters.

Q:I bought a new ceiling light and wired it myself. But I cheated by just copying the wiring from the old bracket into the new one. I want to do the other ceiling lights in my home. Supplied with the lights I am using is a 3 - way bracket (sori if terminology is wrong). Anyway the old bracket I copied was 4 way. My lights are wired from the mains supply with 3 live wires, 3 neutrals, and 3 positives. The light unit only has one live/neutral/positive wire. What do I do with the extra mains supply wires? I hope I have made myself clear as I even I am confused. Many thanks.

One set of wires will be the mains feed the 2nd set will be the mains feed to the next light in the circuit and the 3rd set will be the switch wire. Copy like for like when changing them, taking care not to lose sight of the switch wire...

Q:I have a physics project and my teacher is saying that we should do a wire loop toy?? What the hell is that. Can anybody give me a example and how it is related to physics?? Pls answer back

Wire loop toys mean wire connected to your toy and a handle along with battery.

Q:How much wire is required?

Length of wire is L = R*A/p SI units must be used, so convert radius to meters: r = 0.0254 / 64 m using 25.4mm = 1 inch r = 3.969*10^-4 m (0.3969mm) So cross-sectional area is A = pi*(3.969*10^-4)^2 m^2 A = 4.95*10^-7 m^2 The average resistivity of nichrome is p = 1.1*10^-6 ohm-meter So the required length of wire is L = 2.2 ohm * 4.95*10^-7 m^2 / 1.1*10^-6 ohm-meter L = 0.990 m

Q:Connecting a Pioneer AVH-P1400DVD to a 2008 Kia Sorento. I have connected the wire harness to the back of the stereo by matching each color. My issue is I have 2 wires left on each side.I have a blue wire on the wire harness, and on the stereo side I have a blue/white wire that says system remote start. Do these 2 need to go together, even though they are different color scheme, yet both are blue?Same thing with the orange wire on the harness, and I have an orange/white on the stereo, do these two need to be connected?Thanks!

the orange wire on the radio is for power antenna unless u have a antenna that automaticly goes up and down u dont need it and the blue 1 on the radio is for a amp unless u have a amp u dont need it either the orange on the harness is most likey the power antenna so u can install with if u dont already have 1 and the blue idk i would have to look at it that ant how my radio wired up but i have a JVC lol but i do know all those radios are the same just it at radio shack u will see plus ur tell meh that im wrong when i can and do have a car radio wired in my house

Q:I'm splicing four pieces of 14-2 gauge copper wire to an 16 gauge electrical cord. The copper wire doesn't have any covering on it. Is it okay to connect the grounds, then attach it to my keyless lampholder? Or is something bad going to happen then?

Ground wires are typically bare. Just be sure as you put the wires and light back in the box that the ground wire is not near the connector with the black wire. The black one is the one that bites !

Q:I wired an outdoor lamp-post. I tested it before wiring it to the fuse box...and if I touch the lamp-post I feel the current (a slight shock). I will be using a ground fault breaker....so I assume if I wire it to that I am going to loose the connection. Any thoughts on what is wrong?

In addition to the answer Paul gave, check the wiring that the white wire is the neutral or common wire and that it goes to the shell side of the lamp holder. A few years ago, I had a similar problem, when all of the checks were made, the panel was wired with the black wires on the neutral buss. Hence all of the devices were wired backwards. Call a qualified professional electrician to do the work.

Q:How do you wire a 2 wire smoke detector directly to an alarm (no panel). The terminals are numbered 1,2,3,4 and the instructions say that 1 is for DC+ and 2 is for DC-. How do I wire an alarm so when the detector senses smoke, the alarm goes off? Thank you.

A 2-wire smoke detector? You mean one that plugs into AC? You cannot wire those into any alarm system. If you had a 3-wire (for linking multiple AC-powered units), you might be able to connect an external 120vac relay that closes the alarm contacts when the third (often yellow or blue) wire is switched on. Hardwired smoke alarms for an alarm system get a 12vdc voltage from the panel and also have a pair of dry contacts that are either normally open or (more likely) normally closed until the sensor is triggered.
