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.

That is a sociologic/economic. not technical issue.


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.

I don't know what your load is. The US load per branch circuit is 1800 W,
before the circuit breaker in the box will trip. I think a GFI will trip at
10 microamps.
