| To EFC. {E. Fowler Clarke - Electrical Engineer} from R. {Sir Henry Royce} Copy to CJ. " " HS. {Lord Ernest Hives - Chair} " " BY. {R.W. Bailey - Chief Engineer} ORIGINAL RECEIVED AUG 1921 WSH AHT X4338. RE EARTHED ELECTRICAL SYSTEM. It will be understood that on "Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) II" we have an entirely earthed electrical system. We are proposing to use an exactly similar system on the small 14 H.P. [Handwritten] We are at present designing R. {Sir Henry Royce} the switch (combined switch, charging & lighting) but handle locked switch. The distribution board is a very small simplified R & the automatic switch is to go on the dynamo so that the wiring will be extremely simple, complete & free and concealed. | ||
