| To EFC. from R.{Sir Henry Royce} Copy to C.J. " " H.S. " " BY.{R.W. Bailey - Chief Engineer} ORIGINAL X4338 WAH EHT R5/G29/8/21. X.4338. RE EARTHED ELECTRICAL SYSTEM. RECEIVED. It will be understood that on "Goshawk II" we have an entirely earthed electrical system. We are proposing to use an exactly similar system on the small 14 H.P. We are at present designing R.{Sir Henry Royce} the switch (condensed of Bosch, charging & lighting) two handle locked switch, the distributor board is a very small 2-way-field. R & the automatic switch is to go on the dynamos. so that the wiring will be rendered simple as possible and cost reduced. | ||
