And the incoming cable has to be 35mm2/50mm2 Cu to allow 100Amps single ph which are usually only 25mm2 i.e. 60Amp max.

You will have to upgrade incoming TNB cable size to allow single phase 100A.. Better to apply 3phase for that kind of loads.then they just pull another 2 wires 25mm2 Cu..

Yup and tnb will sure come of the phases are too much unbalanced wink.gif

Dig out some old photos of my house, the old meter is 10-50, and my new meter is 10-100, my mom house new meter is 10-100 also. I remember her old meter (also white casing but first generation) was around ~60.
