CABLE SELECTION Q 8. THREE three-core V75insulated, sheathed and armoured copper cables, including earthing conductors, are connected in parallel to supply a three-phase distribution board with a total maximum demand of 285A. The cables are protected by a HRC fuse and installed unenclosed in trefoil clipped directly to a wall. Neglecting voltage drop, what is the cable size you would install for this circuit? Table details, calculations and units must be shown to obtain full marks.
