RE HEAVY CURRENT CABLE FOR CONNECTIONS FROM BATTERY TO TERMINALS Herewith is a sample of cable received from the Chloride Company in connection with heavy current connections to battery. This is approved by Mr. Royce electrically but he considers mechanically that it required an additional braiding or rubber covering to minimise the possibility of chafing through. The cable consists of 110 wires No. 25 gauge. Two short lengths of this cable will be required per chassis, each fitted with a pair of terminal lugs for which Mr. Day has not out designs and which are to be made in our own Works. Therefore we should obtain such cable in coils allowing about 3' 9" per chassis. Will you kindly write to the cable manufacturers with a view to their supplying us with such cable, with additional covering. Cable with copper wire braided covering is unsuitable for immediate connection to the battery on account of corrosion. We should say that a number of lengths of cable similar to present sample have been received from the Chloride Company, each fitted with one terminal lug, which means that if we require such connections before the receipt of the right cable and before the correct lugs are available, we could make up connections using the lugs received, and using a small quantity of similar cable which we could, no doubt, obtain from the Chloride Co. quickly for this purpose, as they would, undoubtedly have a stock of this on hand.
