Oh, Thanks for that. something else I didn't need to know. haha. I have managed to smash the the rod in the ground further. now it's down 5ft. I hope that totally fixes any problems. I'd sent pics but my iPhone doesn't want to communicate with my MacBook. haha. absolutely stoked with the help here. My next project is to fix the water leak somewhere in the mains line. The housing estate we live in is about 5 years old and now we have problems with the mains pressure. and leakage.????

Hi everyone, thanks for all of your feedback. I bought a 5/16(8mm) x 6ft(1.8mt) solid copper rod plus a copper clamp and (copper?) bolt and 2.5mm square earth cable. I managed to belt the rod about 2/3rds the way into the ground ( 4ft or 1.2mt ) with a very small hammer that came in a cheap tool kit. I then wired, all 4 a/c units, with the 2.5mm cable and bolted the 4 wires to the rod. I noticed that only 1 a/c unit was giving me an electrical shock when I was playing with the cable. I can now touch that a/c unit, with wet feet and ground, and not get a boot from it. I feel much better now knowing I can leave the little lady, while I go back to oz to work, at home and not get electrocuted. I am guessing 2.5mm cable is sufficient in size? Thanks to all of you for your advise. It's the first time I needed to ask a question on here, no doubt it won't be the last. Cheers.

Ok, thanks everyone who replied. I will be off to Homepro for a copper rod and other bits tomorrow.

Cheers.

Ah, ok. Do I just wire it to the metal unit then stake it to the ground or is there an earth connector, in the wiring box in the unit, that I connect it to?

I couldn't say whether its grounded correctly or not. what is/are a copper hods? I thought the a/c just needs an earth put somewhere, but Im no electrician. I know in oz the houses have an earth wire staked into the ground.

Hi everyone, would there be an electrician on here from either Australia , New Zealand, UK etc? I have a question about an air conditioner my fiancee had installed while I was in oz. The a/c is split system, the motor/compressor is outside near the garden. I returned home here in Chiang Mai, yesterday, and while watering the garden and admiring the work my fiancee had done when I leaned on the a/con unit and got a slight electric shock. I wasn't sure whether it was electricity stored from my body so I touched it again. Sure enough, I got another boot. I had wet feet and was standing on the wet ground, My fiancee said she had various workers here doing an extension on the house and thinks the sparky was not registered. My question is, what can I do to the unit to stop the electric shock? Do I need another electrician or can I put an earth strap somewhere or whatever needs doing to stop it.

Cheers.
