Hey, I'm currently in training and I'm stuck on this question! I would really appreciate some help in how to calculate the answers thanks
A circuit to supply a load of 2.75kW at 230 volts 50Hz.
A BS 5467 PVC insulated and sheathed, steel wire armoured cable is to be installed clipped to a perforated metal cable tray, with a total cable length of 30m from the distribution board.
The distribution board is located at the supply intake position. For most of its length the cable is installed touching two other cables in an ambient temperature of 45 degrees.
If protection is by a BS 88 type fuse and the voltage drop must not exceed 5%, what is the minimum size of cable that can be used to comply with both current carrying capacity and voltage drop constraints?
