[QUOTE="Phoenix, post: 356508, member: 8133"] I think you are perhaps confused about how to represent the arrangement on an EIC. As you have no doubt understood from the other replies, the Ze and PFC etc in characteristics of supply on page 2 refer to the origin of the installation where-ever that be. Now page 4 and 5 are DB schedules, now you have installed a submain from a tap off unit, so fill this in as is the tap of unit were a DB with one circuit / switchfuse etc. Zdb and pfc taken at the tap off unit (or at the far end of the busbar if you prefer), zs for this circuit will therefore be the measurement at the new board (end of the new submain). Now you'll have to start a continuation sheet to refer to the final circuits fed from your new DB, obviously Zdb and pfc on this one refer to the measurements at new DB [/QUOTE]
