That is why a 120/240v GFCI costs about 3x what a 120v one costs.

Our system is so much simpler. There really is no reason to have
110V equipment.


The typical home only needs 240V for a few high-power items, so why
wire the whole house for an unnecessary voltage? Adding a center-tap
to a transformer is cheap. Rare to need portable 240V items where
GFCI would be important.
