exception is made in the caseof three-wire (not three-phase a. c, however), systems. In these thefuse may be omitted in the neutral wire, provided this wire is ofequal carrying capacity with the outside wires and is reliably grounded,since in such a three-wire system the neutral wire cannot under… … WGROUNDFig. 69. Fuse Arrangement for Three-Wire Circuit outside wires are also opened, as might occur if a neutral fuse aloneblew, or was removed without the others also opening. Fig. 69illustrates this point. When the fuse in the neutral at iV is in place,lamps A can have only 110 volts across…
