This is an As-built drawing of how my home was converted from 120vac to 240vac The house now has the Neutral moved in the house and used as L2 power source Each circuit had the neutral moved from the Neutral bar and attached to a breaker on the L2 side. Now the circuit has L1 and L2 load making 240vac. Ground wire is connected to the outlets and lights so we have to be careful not to get between the Ground and L1 or L2 load wire. It has been working for 15 years now.
Note we are not in USA and in an isolated area with no inspection and rules. Just wanting to check, knowing the safety concern with the ground and possibility of electrical shock what other concerns might be known.
