I think there is an inherent safety factor in a system where neither side of
a 240V circuit is more than 120 V above earth potential. Never heard of a
person being electrocuted who was not standing, or otherwise submerged, in
water. This costs money.

Its a known deal that 240v is safer than 120 for 2 main reasons.
1. The main killer is not electrocution, it is fire.
2. 240v gives much better discrimination between normal and fault
loads. IOW faults have less chance of tripping a breaker in time on
120v circuits.
