hm, never thought of that...
im not saying the calculator is exactly right or anything...but it should help some
2/0 welding is close in size to 1/0 kicker. So being that we don't know what the calc is based off of it is a little inconclusive.

But the point was that a shorter run would handle more and the calc proves that.

 
THAT SPECIFICALLY STATES330amps OF CURRENT

SO....STUPID....

THIS IS HOW YOU CALCLATE IT.....

FOR EVERY 330 AMPS OF CURRENT YOU WILL LOOSE .05volts

SO IF I AM PULLING SAY 990AMPS. WHICH IS 3 * 330 = .15VOLTS OF LOSS
you fail once again...learn to read

shoulda tought you that in jail //content.invisioncic.com/y282845/emoticons/hilarious.gif.02a037aad04aa96f19982b298a3d70a8.gif:hilariou://content.invisioncic.com/y282845/emoticons/hilarious.gif.02a037aad04aa96f19982b298a3d70a8.gif:hilariou:

and to spell and use proper grammer

lolololol yea u got it bud //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

 
If we had a 1/2 horsepower motor designed to run on 120 volts, nominal, with a F.L.C. of 9.8 amp as per NEC Table 430-148 , and we lost the 3.6 volts due to a long distance run causing the above calculated voltage drop this motor would now be pulling at the full load amps as follows;

Special Notes: You must change the Amps into Volt-Amps, in order to accomplish the conversion, in the change of voltage, due to the voltage drop calculated above.

9.8 AMPS x 120 VOLTS = 1,176 VOLT AMPS

1,176 VA DIVIDED BY 116.4 VOLTS AT END OF LINE = 10.103 AMPS

Formula to change amps into approximate volt - amps = amps x volts = volt amps

Example of Voltage Drop, Approximate "K" And Exact "K"

Calculating the Resistance of a Conductor = (K) (Approximate K & Exact K)

Approximate K = 12.9 for copper.

Approximate K = 21.2 for aluminum

VD=2xKxDxI/Cm

I= Current

2= round trip loss (you'd use 1x if it was a balanced wye circuit)

KxD/Cm represents the resistance of this wire.

Voltage Drop = 2x Current x Resistance

D=length of wire

K/Cm=resistance per unit length.

K is the unit resistance of copper per circular mil

Cm is circular mills of the conductor. (roughly 2.8 Ohms/kcmil/100 feet DC) This equation is only accurate for DC. You can approximate AC (K is roughly 1.3 for AC), but it varies by cable size due to skin resistance and isn't terribly accurate.

Really, you should also be adjusting it forpower factor and the type of conduit it's in and wire temperature, too, but usually if you have to go into that much detail, you should be upsizing anyhow.

SORRY.. i also learned to type 110wpm as well.

oops... i forgot one letter.
