Periodic Inspection and Test

[motnosam]

If a 3 phase D.B. is supplying a number of circuits including a single phase C.U. (which is then used to supply sub-circuits), how should this be shown on the Inspection and Test paperwork?

 

[scotsparky]

Just show the sub mains as a circuit saying where its going with test result to other board. Treat it as a normal circuit with the Zs being at the single phase board.
Then test the single phase board on a seperate Shedule of test results sheet.

Agree with the advise given

The dist boards can be designated as DB1 (main) and DB2(sub)
