Filling in Electrical Installation Certificate

Stuy · Oct 20, 2015

I've never filled in an Electrical Installation Certificate before and just need to query something. The circuit to be tested is a supply for a 3Ph machine. The machine is supplied from a DB which is fed from a Section Board which in turn is fed from a Main Section Board.Section Main Switch / Switch Fuse / Circuit Breaker / RCD - Is that details from Main Switch on Main Section Board, Section Board or DB.My Ze and Pfc readings to be taken from the Main Section Board ?

Do not post the same thing twice.
Use the DB for main switch
Use main section board for Ze and PFC (if you can get to them and switch them off.)
If not then use Zdb as your Ze and confirm DB PFC is OK for the DB in any case.

How many main switches does an installation have?
