its one phase... we only have 240v monophase and 380v 3-phase... we use RCD switch instead of gfci and afci, its enough to protect from both arcs and ground faults, and it is installed in panel boxes before all breakers, so its also used as main switch, we measure wire thickness in mm2, starting from usually 0.5 mm2 to lets say 6 mm2, which is equivalent in american 16 awg to 8 awg, and we use concrete to build houses, rarely or almost never wood, so also, construction-wise, we do things differently...Is your 240 V single Phase? I think not but is it?
It's interesting to learn about other cultures.
thats why i have no clue about your way of doing and need to research, a lot, because i cannot tell something before i check if its inside your electrical standards, some things really make no sense to me, and its exausting to convert everything (we use metric system, thats enough for me to get lost in rabbit hole)...
