| Contd. -8- EFCl/Tl.10.23. has proved that it is not possible with this fuse in circuit to run the solder from the commutator connections with the dynamo on the chassis. One one or two of the experimental cars, we are arranging to put fuses of this size of wire in the field circuit, not so much with the idea of proving the degree of safety afforded by this fuse, as in proving that the fuse is of sufficient current carrying capacity to stand up to all normal conditions. Speaking of fuses, we have always considered that it would be much more convenient for the customer to be able to carry spares of ready loaded fuses, rather than to carry reels of spare wire, it being so much easier to replace a fuse thus provided. The operation of reloading fuses can be readily carried out at home. Further, there seems a good deal to be said for the type of fuse consisting of a small glass tube with small brass ferrules, ane at each end, though the holes in which the fuse wire is threaded and soldered, the fuse holder consisting of two clips for the ferrules. This type of thing might be suitable in this particular instance and provide the necessary difference from the other fuses. Spare fuses would not be expensive and a dozen or so could be given to each customer. EFC+ | ||
