| To EFC. from R.{Sir Henry Royce} -2- R2/G9/6/19 Contd. RE ELECTRICAL CONNECTIONS ETC. ------------------------------ are so enormously complicated, and subject to sea water, that one would conceive that a double system of wiring (at least part) would soon be substituted for the earth connections. I always used the double wiring arrangement on ship work that was done by the company I was with in quite the early days of 1884. R.{Sir Henry Royce} | ||
