In a 480 volt wye connection you obtain two voltages, 277/480 volts. Any leg to grounded wye point will give you 277 volts. Between any of the legs to each other you will receive 480 volts. Any two legs of a three phase system is classified as single phase supply. From a 480 volt central distribution panel install a two pole breaker sized to the amperage shown on the welding machine. Be sure to use the input current and not the output current to find the correct feeder for the unit.

What is c program of roman numbers?
There being only 7 symbols to consider (IVXLCDM), conversion is easily achieved in any number of ways. In general, numerals are formed from left to right, largest value to smallest. However, if a smaller value precedes a larger value, the smaller value is subtracted from the larger value (or is negated). This can lead to problems such as IVX. Reading left to right this would become 10 - ( 5 - 1 ) = 10 - 4 = 6. There's nothing wrong with this, but most people would accept 6 = VI, not IVX. The problem is there has never been an official standard relating to how Roman numerals are formed. Decimal 1999 could be represented as MCMXCIX or MIM or MDCCCCLXXXXVIIII or even a mixed format like MCMXCVIIII. All are intrinsically correct. However, only the first example conforms to what many would consider to be the "unofficial" standard, whereby certain combinations are no longer permitted (such as IIII, IM and VX). This standard has been incorporated into the following code. #include <iostream> using namespace std; int main() { char roman[11]; int decimal[10]; memset( roman, 0, 11 ); memset( decimal, 0, 10 * sizeof( int )); cout << endl; cout << "Enter a Roman number (max. 10 chars from I, V, X, L, C, D or M): "; cin.getline( roman, 11, '\n' ); strupr( roman ); // convert to uppercase for consistency // check validity, including all invalid combinations if( !strlen( roman ) ( strspn( roman, "IVXLCDM") != strlen( roman )) ( strstr( roman, "IIII" )) ( strstr( roman, "XXXX" )) ( strstr( roman, "CCCC" )) ( strstr( roman, "MMMM")) ( strstr( roman, "IL" )) ( strstr( roman, "IC" )) ( strstr( roman, "ID" )) ( strstr( roman, "IM" )) ( strstr( roman, "XD" )) ( strstr( roman, "XM" )) ( strstr( roman, "VX" )) ( strstr( roman, "VL" )) ( strstr( roman, "VC" )) ( strstr( roman, "VD" )) ( strstr( roman, "VM" )) ( strstr( roman, "LC" )) ( strstr( roman, "LD" )) ( strstr( roman, "LM" )) ( strstr( roman, "DM" )) ( strstr( roman, "IIV" )) ( strstr( roman, "IIX" )) ( strstr( roman, "XXL" )) ( strstr( roman, "XXC" )) ( strstr( roman, "CCD" )) ( strstr( roman, "CCM" ))) { cout << roman << " is not a valid roman number." << endl; return( -1 ); } // convert to decimal, in reverse order. int c = 9, total = 0; while( c >= 0 ) { switch( roman[c] ) { case('I'): decimal[c] = 1; break; case('V'): decimal[c] = 5; break; case('X'): decimal[c] = 10; break; case('L'): decimal[c] = 50; break; case('C'): decimal[c] = 100; break; case('D'): decimal[c] = 500; break; case('M'): decimal[c] = 1000; break; } if( c < 9 ) // subtraction required? if( decimal[c] < decimal[c+1] ) decimal[c] *= (-1); // negate // update total. total += decimal[c--]; } cout << "Roman " << roman << " is decimal " << total << endl; return( 0 ); }

If you use a lower case "i" the Roman Numerals will all be in lower case.
