Hi,
So, I have a heating element @ 10kW capacity. Since heaters are resistive load (fix I assume), given a constant voltage hence, I will have constant current though out the operation. My assumption based on the above statement is, given a range of 1-100 C (being 100 C the maximum temp it can attain, for example), the current will be equal on 99 testing points (@ 1 C graduation).
If so then, why a need for a fuse/ circuit protection as indicated on Electrical standard?
