In this example i have one 16awg wire feeding five 16awg outputs for power distribution. Try to insert the end of the input wire into the center of the bundle. Using one 240 volt line to power multiple 120 volt circuits reduces the amount of wire needed and the number of circuit breakers needed in the main power panel. Its much easier and much less expensive to replace the 4 wire whip with a 3 wire whip.
