Zyxel, better clean up your act.

Good on them, great to provide more links to the two countries.

Yes first class insurance just call the insurance company and their rep. handles it.

Let us know what your decent build is please. ????

I found it pretty good myself.

Thanks @SomchaiDIY I hope the moderator doesn't mind me saying this but you are a welcomed addittion to this brilliant forum. Not detracting from the other posters (except the guy redoing his condo who rubbished posters). ????

Got it all sorted?

KhaoYai said: 'I was a little confused as to why you needed a heater in Thailand.' Gets cold in Isaan near Lao. Gets down to 4 to 6 degrees C. So the other heater was a water heater but this one in the picture is the house gas log fire. Sit around in your undies, drinking red, watching the flames flicker. ????

The 3 phase multi-point heaters are great. Fairly instantanious full flow hot water, but I wouldn't install them again. Before I built the house we had a 3 phase supply close by from a de-commissioned rice mill, so we just asked PEA if we could move the meter and use it. Very difficult then to get a real electrician that knew about 3 phase installations. We eventually got someone who installs power in factories and he was the one that said to install the 3 phase heaters.

I think this is a direct quote from the information sheets from the company.

Reply from the company in Germany. 'You cannot connect RCBO for Steibel eltron 3 phase water heater. As they require wiring of 3 phase + Earth. RCBO will not operate since there is no Neutral connection. Would Suggest connect TP MCB for protection. Ideally we suggest individual MCB's to be fitted in the Main DB box for respective equipment and an Isolator switch be installed for maintenance inline near to the equipment.'

Chinese aren't Farangs, they are Khun Jeen. Have you ever looked at one? Something wrong with your eyes if their features look anything like a Stale White Person. ????

Pattaya's full of Dirty Old Men .....so they say.

They all are.

Thank you for this detailed response and the unit sounds safe. I got a quick phone call response from Thailand but no response from Germany. Maybe some of us Falangs get a bit carried away with safety, but it is hammered into us when we did our tech training. When I started on my 5 year Telecommunications traineeship in 1963, some trainees were cutting their hand, so eventually they banned the use of knifes. Also later on a couple of trainees were electrocuted working on live switchboards, so they banned us working on power. And so it goes. ????

That's what I thought. I know it happens, but It's pretty disturbing when the company technical division gives very bad advice. Makes you wonder if any water heaters of this brand have RCBO protection. If you can just bear with me a little longer. ???? The 3 phase water heater is earthed, about 3 m away from the shower, connected by PVC pipes to the metal shower taps, set in bricks and mortar, not physically tied back to the earth system. The water is very pure (lots of filtering). I have an MEM system. Just say one element developed a short to ground. How's them there deadly electrons going to get to me, enough to ruin my shower? (Go easy, it's Friday).

I just had a phone call from Steibel Thailand. Previously I'd made enquiries about installing an RCBO on the 3 phase water heaters. They ensured me that if the heater has a ground wire, it doesn't need an RCBO. I asked them to check again with the technical department and they said 100% sure. So does the water heater need an RCBO?

Log fire at the ready.

Thanks. In my case the multi-point heaters are in a domestic house. Heaters are fed from the house CU, which has a lockable door. The heaters are mounted under the kitchen bench and under the laungry bench. Next to each heater is another 3 phase breaker. I don't have an actual lockable isolator next to the heater unit. I read that now (in Aus) each sub-circuit final must have a RCB/RCBO. Does that mean each seperate feed from the CU must have a RCBO? Eg. Stove, kitchen.

I'm only 77 and also forgotten most of this even though I taught it to year 12s before. What I can remember (sort of) is Excel have a very good Help menue. Go to the Help menu and type something like: how do I insert a forex line chart?

Which is what @Crossy said yesterday. Sorry for that. ????

I think the heater is wired in a Wye configuration. I have found a couple of 3 phase, 3 pole RCBO's with Neutral connections. I presume the neutral would go from the junction of the Wye back to the CU neutral bus. 3 phase, 3 pole RCBO, something like this in the picture?

Thai/German have a big college in Chonburi or maybe Satahip, not sure exactly which Changwat it's in.

For the 3 phase water heater, should you use a 3 phase RCB, or wouldn't it work in this application as there is no dedicated neutral to the heater? It seems from the wiring diagram that the active to one end of the heater returns via the earth, which is connected at the CU to the neutral. Maybe reading the cct wrong. So the question is should you use a 3 phase RCB?

Sounds like you're one. Absolutely no idea. Many people live in Pattaya because they work there Richard Cranium. Many Falangs work at the International Schools. Many Falangs work in The Eastern Seaboard. Many Falangs work at Lam Chabang Port. Don't thank me, just trying to improve your knoweledge. Now IQ is 20.
