Hi guys

I have a query. I got a new inverter aircon installed today (18000 btu). So in accordance with law an isolator was installed (30a) from a new mcb (30amp) on the DB Board. So when we switched the aircon on earth leakage tripped - it happened every time the breaker of aircon was turned on.
The installer then said we need to bypass the earth leakage for aircons esp the inverter aircons. So he bypassed the earth leakage to connect the aircon.
Is that right - aircons should not be on earth leakage and should be bypassed or is there an installation problem here
Thanks
