Crossy............. not sure that you got my latest, I had a non-sense message from Thaivisa.

Here is a copy :

Thanks again. At the risk of overdoing your patience............ I have looked at Safe-t-Cut web site which is poor. They show a confusion of slightly different models of stand alone RCBO's. I hope to buy one tomorrow.

I guess that 32 amp would be ok. Do you have an opinion on which model, please ?

regards

Hmm, didn't get that one

Check the meter, if it's a 5/15 get the 16A version, if it's a 15/45 get the 50A version. Either way it will have a switch defining the RCD trip current, do NOT set it to 'bypass'.

If they may upgrade to the bigger supply in future get the 50A but ensure that the incomer on the CU is suitable for the current meter.

This is probably the 'standard' unit http://www.safe-t-cut.com/บริษัท เซฟ-ที-คัท (ประเทศไทย) จำกัด 1-13.htm check what your local emporium have in stock.
