[QUOTE="alextrician, post: 269095, member: 18366"] thank. I really apreciate it. I've got all tables in the appendix 3 of the regs book, but i don't know how to use them to figure the disconnection time or that is the purpose of these tables. [SIZE=8px][COLOR=#C0C0C0]---------- Post Auto-Merged at 02:58 ---------- Previous post was made at 02:12 ----------[/COLOR][/SIZE] 1.a) Determine, using the aiding drawings the minimum csa of live conductors suitable for current carrying capacity and the volt drop for the following circuits. The rating factor for grouping are based on the above for circuits within the same containment system with the ambient temperature of 25C In order to determine the cross sectional area of the live cables and volt drop for all the circuits, we need to find out the current drawn by the each particular machine, the rating of protective device and type, a method of installation, any available correction factors and the maximum and the actual voltage drop.
