3Phase AC: 400 V 415 V: Large loads and consumer mains. 1 Phase AC: 230 V 240 V: Smaller loads and consumer mains. DC: 12 V 24 V 110 V: 2 Phase 120° 400 V The worst-case power factor is when the cable and load power factors are the same. The voltage drop formulas are shown below. 1-phase AC \(\Delta V_{1\phi}=\dfrac{I \cdot L \cdot 2
10A 20A, 32A - These are three most common 3 phase plug and socket sizes used in Australia. "A" refers to the maximum Amps the plug is rated for. 4 Pin, 5 Pin - With each of the 10A 20A 32A options we also have a variant which has a 5th pin added in the centre. This is where the Neutral wire is connected. ACpower, normally at a phase voltage of 115V, is generated by an alternator, generally in a three-phase system and at a frequency of 400 Hz. Running at 115v 400Hz allows the use of smaller transformers. Less energy has to be stored in the transformer core per cycle, so the core can be smaller. A smaller core means a lighter transformer, andFullload current in amps for single phase alternating current (AC) motors from Elliott Electric Supply, a wholesale electrical supplies distributor.
