Aircon keeps triggering circuit breaker after 1-2 minutes of operation

You have ruled out the compressor ? Fans are normally a much less loading on the supply. What type of breaker ie. with or without earth leakage protection. With respect you may be a tad out of your depth here.

Yes. It is normally associated with too small a breaker current for the start current of the compressor. Check the specs in the installation instructions / user manual and compare these to the rating of the breaker installed. Quite often sparkies who want to skimp on using the correct gauge cable for the load current / distance fit a smaller breaker to prevent the house catching on fire in the event of a fault / too high a stall or start up current in the compressor motor. The indoor unit is most likely running on a separate circuit or breaker. Get it fixed if it has been recently installed or under warranty - should cost nothing to fix a stuff up. If out of warranty get a qualified a/c sparkie to check it out.

If so, it may well be the fault.

You really need a "clamp meter" for this sort of thing.

Or just call a sparky.
