Just to share,
An undersized cable will be a heater and adds a lot to your electricity bill..
On starting an induction motor draws 6 times the running amps and will damage switch contacts if not properly installed.
Thus do not only look at a motors running amps when sizing a cable or starting contact switches. It will wear out and adds to your electricity bill if done wrong.
Which one matters more? The cable running to the indoor unit or the cable running from indoor to outdoor?An undersized cable will be a heater and adds a lot to your electricity bill..

Asking because my electrician pulled 2.5mm2 Caramay cable for use by the indoor but when the aircon installer came, they used a not well-known brand (though SIRIM approved) 2.5mm2 wire.
I compared and noticed the one the aircon installer used is thinner than the Caramay cable. Asked if they have other better cable but they said no.
Distance is around 2m from the indoor unit to the outdoor unit and it's a 2.5HP inverter aircon.
Not sure if i should be worried. Your thoughts?
