Electrical have rule to follow. Not what you want 100A this and that.
Max single phase is 60A. So everything must be content in 63A. Fuse or isolator. More than that, advise you to get 3phase.
Your single room heater and aircon share the same point is not recommend. Even you change the MB to 40A, your wire spec exceed the actual current running. Heater 3.6kw and aircon 1.5HP 1.2kw = 4.8kw. Your 2.5mm wire is running hot.
As a precaution, separate into 2 point with 2pcs MB is the proper way.
Yes correct, 40A mcb is irrelevant for house, i would blame the owner bcs he might not know about the danger, but definitely will blame the electrician, how stupid he is, how can he change mains switch 63A to 100A and cut out fuse too 100A,its just house, less protection, and do not share heater and aircond,most probably the cable.is 2.5mm... omg i had stroke reading this....Max single phase is 60A.
