Load calculation and size of wires

I have one project of hotel electrification i wat to know some electrical data

  1. How many Amp cureent drawn by different size of copper and alluminium wires ( Armoured,Unarmoured )
  2. how can we calculate load,when the appliences are run on 230 Volt.
  3. how can we calculate load,when the appliences are tun on 440 Volt
  4. please give solution on Amp wise use of copper/alluminium wires.

A lot of your questions also have distance that need to be factored in. Copper is way better than aluminum. but in large wires it may be too expensive, also some suppliers only carry aluminum in the largest sizes. If you are doing a lot of electrical, then you need to learn "ohms law." Also most appliances have the amp load printed on them on the I.D. label.

    What part of the answer was inappropriate, ****. o.k. 20 amps, 40 amps and 100 amps on the big plug. do it that way. If you don't know what ohms law is don't f...k with electricity!!

I Am installing a Generac 20Kw air cooled unit with a 200 amp service disconect ATS What size conductors do i use from the generators 100 amp breaker to the transfer switch


It is always good to install a large enough wire where the maximum load can be drawn plus a little extra for safety. 7 gauge wire will do, if it was mine I would use 6 gauge wire. If the length is over 20 feet but not longer than 80 feet go to the next larger size wire.

Can a Cutler Hammer 2 pole 100 amp CH series circuit breaker be connected to 2/0 aluminium wire in a branch feeder circuit?


I answer questions for free
I specialize and timers and electrical devices
Looking up your breaker at Eaton, I found the chart that shows below:
Other than the chart, I do not know the specifics of your breaker.
You can add a comment, and I can help you with your wiring project.
Another good source of information about specifics are your local Graybar electric supply house, or any local supplier that specializes in electric wiring.
Having a local electrician stop by and look at your project for a fee might be a good investment long term because that person knows local codes and restrictions.

How to use casio calculator in solving regression problems


I am sorry but I will have to assume that you know how to enter the data.

Once you enter your data [MENU][STAT], press [F1:Graph], select Gph1, Gph2, or Gph3. Once the graph of the experimental data is drawn, you will have access to the diverse regression models. Your choices are [X:Linear] [Med-Med], [Quadratic :X^2] [Cubic;X^3] [Quartic: X^2]. Press [F6] to scroll right to access the others: [Logarithmic:LOG], [Exponential :EXP], [Power :Pwr] and [Sinusoidal: Sin]

After you select a model and press [EXE], the screen displays the equation and its various coefficients. On that same screen, you have a menu option [F6:Draw]. If you select it, the regression curve will be drawn on the same screen as your statistical graph. This allows you to judge if the fit is good. If it is not, you have the option to choose another model.
The other option [F5:Copy] allows you to save the regression equation in the Y1, Y2, etc. variables.

PS If you do not know how to enter data post a comment to this effect and I will see what I can do to help you.

How do i find the constant in a half life equation?


Hello,
I have no idea what can of data you have, so I am taking a theoretical stance. In a radioactive decay the period of half life is the time after which half the nuclei have desintegrated. Let us call that period tau τ.
The constant, usually called lambda, λ appears in the expoential. It is the constant term that multiplies the time variable, t.
If you have y1 nuclei at a time t, and y2 nuclei at time t+ τ., the ratio y2/y1 =1/2. It is also equal to e^(-λ* τ). Thus
e^(-λ* τ) =1/2.
and ln(e^(-λ* τ)) = ln(1/2)=-ln(2). But since ln(e¨(x)) = x, we get
-λ* τ= - ln(2) and
λ= ln(2)/ τ

In the enclosed screen capture the equation e^(-λ* τ) =1/2 is solved for λ
12470f3.jpg
If you have experimental data, or a radioactive decay curve drawn you can obtain the constant λ , as the negative of the slope of the function at t=0. See on following graph. Disregard the values of the function before t=0 ( I should have restricted the window to the first quadrant.) The function drawn is e^(-0.365t)

Can I put a higher watt heat tube in my TQ-10 converyer toaster


Your toaster is rated at 1800watts which is the power rating.
Your toaster is rated at 15amps which is the current rating.
Your toaster is rated at 120v which is the voltage rating.

Electrical Load,Power Rating and Current Drawn through the Main Supply is Calculated By: Power = Amps x Volts
1800=15x120=.........1800w.
Manufactures work out what size of cable and protectio to incorporate by using this design principle.
If you try to increase the bulb size it will alter everything and the internal wiring was not designed to take this extra load.
So, NO...

How to calculate the length of cables and conduit pipes required in electrical wiring diagram of domestic,industrial installation


While determining the cable size makes sure that the wiring system should be in an open wiring system, the temperature would be low, but in conduit wiring, temperature increases due to the absence of air.
The key thing to find cable size is loaded, it depends upon the load how many loads exactly have.
Diversity factor in electrical wiring installation while selecting the proper size of cable for electrical wiring installation.

Subpanel hookup


Yes the maximum size branch circuit breaker that will fit in a residential load center is 100 amps. I would recommend that you calculate the amount of power that you need the sub panel to handle, then add any additional loads you may need in the future. Hopefully this is less than 100 amps. I would recommend that you check with your local electrical inspector to make sure your installation meets all local and national codes before proceeding with the install.
