With reference to your quotation dated 28th ult., we have now tested the samples of wires enclosed there-in and as far as the fuse wire for the switchbox is concerned we find that the sample submitted is satisfactory i.e. 30 SWG. This we find fuses with 5.3 amperes, and, therefore, falls within our limits namely, 4.5, amperes minimum to 5.5 amperes maximum. We shall be pleased if you will inform us by return thereference letters we should use when ordering this particular size of fuse wire as it is important that we always have a wire of the same analysis. On receipt of this information, we will forward to you our Official order. Yours faithfully, | ||
