The job was to install
1. a 400v tpn 8 way db (construction site enviroment)
2. feeding a TX
3. which in turn feeds a 110 v lighting circuit that is not on a plug into the front of the TX, but instead hard wired into a double pole outgoing MCB of the same TX so as to avoid unwanted disconnection of the lights.
1. where/how would i record the cct details/results for the lighting cct being fed from the TX?
2. how do i verify that the recorded results for the 110v cct are within limits for tripping times?
