On the revered CoC, there are some check boxes that bother me:
1. Phase rotation. In the Cape Town area, the phase rotation is ANTI-CLOCKWISE. What is it like in the rest of the country, or are us Capetonians the only ones who have our wires crossed?
2. Prospective short circuit current in kA. How determined?
a) Calculated (Maths is not my strong point)
b) Measured (I am aware there are commercially available instruments that measure this - no maths needed)
c) From Supplier (provided you can get hold of an informed person)
I have not filled in a CoC for years, as I mostly do inspections on existing installations in hazardous areas.
