I had an electrician come out last week for an AC circuit board tripping issue.
He charged me $80 to upgrade the 25A breaker to 32A. The issue wasn’t fixed and I had AC technician come in and they confirmed that everything seems to be ok on the compressor.
After the upgrade, surprisingly when I turn on the AC, it directly trips the RCD(and not the AC breaker).. the AC Technician believes this could be due to neutral to earth wiring issue(or something like that) and advised me to get the electrician again to have a look.
When I called the electrician again, he advised me to have a RCD only for the aircon, so that any issues in future with the ducted aircon will trip the standalone RCD for Aircon and not the entire house.
He said he would charge me $150 in total to replace the 25A aircon breaker with 32A breaker and have a RCD for itself. Is this reasonable ?
Also, does it make sense and are we heading in the right direction ?
Thanks in advance
