Question 5 of 10

5. Question

For Circuit 1, the short circuit power (Icn) is 6kA. Is this potential for braking compatible with the safety device? What step can the inspector take, if not?

For domestic use, a short circuit braking power of 6kA is suitable for Setups; no action is needed
The values of Icn and Ics are rated equal; no action needed
Larger than Icn is the highest measured short circuit current; an Observation Code should be added.
Larger than Icn is the highest measured short circuit current; an observation Code should not be introduced.

Question 8 of 10

8. Question

In relation to the additional ring final circuit for the stage area, what action should the inspector take?

Request the person ordering the work to provide additional data on the job Extra Circuit
Include the circuit in the protocol for inspection and test: the circuit was Designed 5 years ago
Conduct a visual inspection and test the circuit: no paperwork Accessible
