Though more then welcome. That doubles the voltage to ground in parts of the machine.
It is not an illusion, with the center tap being used as a neutral L1-N and L2-N are not in phase, therefore there L1-N and L2-N are different phases and therefore each must have a fault protection device. Thanks in advance RE: I believe it is only confusing. Split Phase Generators Yes, Bill!
If it is a cunsumer taking supply at 240 with center tap isolated and one winding end acting as the neutral it must be single phase. I believe it is B or the two legs of 220 would read 0 volts?
Join Eng-Tips Forums! On the primary side I would just connect R1 and L2 as before. An engineer designs a part in every detail, specifies the material the part should be made from, and issues the order: If B, why is it refered to as single phase? The windings will withstand 240 Volts and more to ground.
A phase displacement is produced by pairing two windings with widely different X: Feedback and Suggestions.
If they were in phase, hence synchronised, there would be no voltage difference the hot wires. No need to spill blood. No it's single phase I think the term Phase is loosely applied to mean wire, winding or angle.

It's a simple 240V winding with a center tap 2x120V ; in such installation central tap it's used to create a neutral, so between neutral and each "hot" leg is 120V; it's not a split phase or dual phase system. As far as op's original question, I would defer to the other knowledeable members.
The neutral and earth bars are bonded together.
