Going from delta to wye?

Looks like the only real option is a 240D to 208Y/120 transformer.

Which will be on the customer's side of the meter, and so will use paid for power every day for years to come... You ought to do a calculation to make sure thats cheaper than whatever an upgrade to a 4W supply would cost, including the prohibitively expensive upgrades. It probably is, but its worth making sure.

Crud, thanks for reminding me of that . Looks like the only real option is a 240D to 208Y/120 transformer.

Sounds like all you need is to supply 120V loads. I was wondering if perhaps a 240 to 120/240, 3W autotransformer would suffice...???
