Hello forum,
The standard just says the components including wiring shall be used in accordance with their specified ratings, but it is unclear how to determine the ratings.
For the current rating of components in primary circuit, three options swim into my mind:
1) not less than the current rating of primary protective devices, such as mains fuses, circuit breaker
2) not less than the rated current of equipment
3) not less than the current that components are intended to carry when the equipment is operating under normal load
Which one mentioned above do you think is correct? Can I have your opinions?
Many thanks,
Roland
