	Figs. 27 and 28 show switchboards suitable for use on board ship. Fig. 27 shows the usual arrangement of circuits on board a “tramp.” It will be understood, of course, that there should be an ampère meter on each circuit, so that the engineer can see what is going on. This, however, is not always done. In many “tramps” not even one ampère meter is to be found.” (p. 95)
