| X6090 EFC. By/RD4/DM{D. Munro}11.3.30. X.7560. X.7561. 40/50 HP. CHASSIS. X6090 ELECTRICAL SYSTEM CONDUCTOR SIZES. It was not our intention when altering the core sizes as mentioned in our memo. By/RD3/DM{D. Munro}3.3.30 to change the colours as suggested in your memo EFC2/MS10.3.30. We will arrange to send you a revised list of wires based on these latest changes, We note that you are proposing to order cellulose lacquered L.T. wire for experimental tests. May we enquire what benefits you anticipate gaining by using this specially coated wire, as we are not aware of any troubles with the present wire used? Do you know if there is any likelihood of this wire being cheaper than our present standard? I suggest that when the experimental wire is ordered enquiry of the price would also be an advantage, By/RD. | ||
