How to find out the Full load current [Relation between horse power and kilo watt] and how to select a proper cable [Power cable size selection chart]

In previous posts i have explained about electrical drawings, electrical panel component etc.. For smooth working of motor which is connected to the mcc panel, cable size selection has an important role. We have to consider lot of things for selecting a proper cable, like motor rating (Kilowatt,Horse power),Voltage(230v, 415 v etc.),Phase(Single, 3 phase),Temperature, Distance between motor and mcc.

Before that i will expalin how to find out the cable current rating.

1.Incoming suppy cable rating.

           Motor Full load current * 1.2
2.Inside cables – Motor circuit cable rating.
           Motor full load current * 0.7

Now you will be having a doubt how to find out the full load current of a motor?

Formula for finding full load current of a motor.

3 phase:
            Full load current=(746*hp)/(1.732*V*pf*eff) or KW/(1.732*v*pf*eff)
                                 hp=horse power
                                  v =Voltage
                                  pf=Power factor
                                 ef=efficiency
                              1 hp=745.7 W=0.746 kw

How could I possibly forget to make a review of X-Men: First Class?

Oh yeah, finals. That's why. So shut up.

If you don't want to read this, I have a video summary on my youtube page here. And here:

Basically, I enjoyed this movie. I laughed. I loved. I had one or two emotions throughout.
Michael Fassbender as Erik / Magneto was amazing. Paired with James McAvoy as Xavier, you have a winning combination  If only they were the only two characters in the film, then maybe things would have been more impressive  Sadly not.

The students/mutants they recruited were... interesting. Banshee was a must-have, so kudos to that. Havok? Clearly an allusion to Cyclops who was actually a member of the first class in the comics, but due to continuity they couldnt' have Cyc in the movie. (Even though they broke some continuity later on.)

Angel was also an original member; remember that winged dude in X3? Yeah, that was the original Angel. Instead they took a pixie-stripper and slapped the same name on her. Who would know, right?

Also, Mystique was hot. Not the blue-stique, but the actress who played the human disguise. Jennifer Lawrenece:

A lovely girl.

As for the rest of the movie, it was fun. It wasn't too serious, it wasn't even too good, but it felt pretty darn 60's and light hearted.

Also, the montages. Oooh, the montages. So fun. So good. Excellent cameo in there as well.

Anyway, I am drunk and must go get drunker. Go see the movie. See you next time when I talk about Green Lantern.

Though on a final note, why bother sticking to some continuity of you're going to kill more of it towards the end? Whatever. Fox can't make a movie like Marvel Studios can.

P.S., don't bother staying through the credits. Nothing to see at the end.
