Ok, i am new in this forum I am looking for some enlightenment. Today I got a call from my boss, which is now in Venezuela and he is connecting a 4000W 100v power plant at his condo. The electrician he found there connected a 2 Throw Switch Knife to the circuit to split the power coming from the electricity provider and the other side to the power plant. the issue for me and that I cannot understand is this.
The electrician connected the right side to the power coming from the city power which is 220V 2PHASE so is PH1 PH2 N,
the output is the same L1>L1, L2>L2, N>N, so far so good.
The generator side, as it it 110V and he wants to power the 110V devices on the both phases, he just split the 110v phase into the 2 PHASES of the switch, so L1>L1, L1>L2, N>N. So when the switch knife is connected to the generator side, the same 110v phase is connected to both the phases of the circuit. for the 110V devices connected there is no problem.
But my question here is:
What will happen with the 220v devices connected in the circuit? will affect them that the Lines are energized with the same phase?
or since there is no L2 the voltage will be 0 and wont affect the 220v devices?
I am worried for the AC units, dryer, etc wich uses 220V.
Can some one explain if this is Safe?
Can also a Automatic Transfer Switch be used instead with this configuration?
