If using the same size wire throughout, one method is to use the "load center". As the circuit progresses, multiply one-way lengths (D) by amperes (I) over that length. Average the products [i.e. (D1?I1 + D2?I2 + ... + Dn?In) ? n] Substitute this average into most any Vd formula for L?I.what the best way to Calculat the voltage drop in the street lighting network??
