You’d have to cut that link before dropping a phase on the return to get 415 past the distribution board... sorta impossible... cut the ground link first then it’s possible... but as every connection has the same, that’s a lot of ground links to cut to make it happen... unless you drop the return on both sizes of your pole and your ground stake and then drop a phase on that floating terminal ... > Best wishes, > Nick. > -- > > > _______________________________________________ > freebsd-stable@freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-stable > To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org" _______________________________________________ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
