POWER

POWER DROP CALCULATOR

Remember when calculating DC two-wire and AC three-wire THAT YOU most also change the wire size since the three wire AC generally uses smaller wire sizes than two wire single phase DC systems do. If you do not change the wire size it will APPEAR as if AC is better for long distance wire runs. The truth is the HIGH VOLTAGE is the key to running power over LONG distances. This has nothing to do with AC or DC. select cable size... 14 awg (15/--A) 12 awg (25/20A) 10 awg (30/25A) 8 awg (40/30A) 6 awg (55/40A) 4 awg (70/55A) 3 awg (85/65A) 2 awg (95/75A) 1 awg (110/85A) 1/0 awg (125/100A) 2/0 awg (145/115A) 3/0 awg (165/130A) 4/0 awg (195/150A) 250MCM (215/170A) 300MCM (240/190A) 350MCM (260/310A) 400MCM (280/225A) 500MCM (320/260A) 600MCM (355/285A) 750MCM (400/320A) HINT: Input the wire/cable size example of ONE LEG ONLY of the AC or DC wire being used in the actual wire pack.  input load current in amperes select voltage... 2V 5V 6V 8V 9V 10V 12V 14V 18V 20V 24V 28V 36V 48V 60V 115V 120V 208V 220V 240V 277V 380V 416V 440V 480V 550V 575V 600V Voltage select system type...
