I am changing an electric shower for my daughter in the morning. The old unit is a 7.9Kw. the cable is 10mm. The existing breaker is a Hagar type B MTN140. Hagar appear not to do a 45A, but it appears, from other old forum responses, that the existing 40A will be okay.
Am I correct in deducing that the 40A is okay, and is better than fitting a 50A?
I am hoping to get a definitive response this evening - I can get a 50A in the morning if that is the preferred option. But I could do without travelling out of my way to get one if not required.
Thanks
