| X 3860 To WD{Mr Wood/Mr Whitehead}/Ms. from EFC. EFC3/T22.3.26. RE "MACONITE" HIGH TENSION CABLE. Confirming our various conversations, it is understood that you will now order sufficient "Maconite" H.T. cable for four chassis - two 40/50 HP. and two 20 HP. The lengths required per set of 40/50 HP. is 37 ft. and length required per set of 20 HP. 18 ft, so that in all 110 ft. of cable are required. It is further understood that the cable will be ordered to a dia. not exceeding 7 mm., but with a tendency to the lower limit given on the drawing, similar to the dia. of the present standard cable. The Maconite cable at present received has exceeded the top limit, being .290" instead of the top limit of .275." EFC. | ||
