Hi. Most grateful for your suggestions on the following. My generator is a Stamford/Newage 125 kva, 1500 r.p.m., 174 Amps, 415/240 Volts rating and power factor is 0.8. The load comprises 36 heating elements, each element rated at 6Amps/ 240 Volts (1500 Watts). I have divided the elements into 3 groups , each group thus has 12 elements. What would be the most efficient way to wire this? Is a phase wire and a neutral per group the way to go? Thanks in advance.
