Air conditioners and other compressor-based appliances have a startup current noticeably higher than their running current, and this surge should be accounted for when planning circuit capacity, since a circuit that handles running load fine can still trip during simultaneous startup of multiple units. Dedicated circuits, wired directly from the distribution board without sharing with other outlets, are generally recommended for high-draw appliances like air conditioners, geysers, and washing machines, reducing the chance of overload from unrelated devices being plugged into the same circuit.
