What more readily available in the world, "wye" or "delta"
What more readily available in the world, "wye" or "delta"
(OP)
I am wondering if it is more common to find a supply voltage in a "wye" configuration, or a "delta" configuration throughout the world. This would be a typical industrial service for a 100+ kilowatt water heater. It seems that the delta is more common in the states, but not sure for the rest of the world. If there are any websites that discuss this, I would appreciate the link.
Thanks
Thanks

In most cases a "delta" water heater can be connected to a "wye" system.

What's the concern whether the supply is wye or delta? If your three-phase heater is delta and the supply is wye, simply omit the neutral when wiring it up.
If there's something we're missing, let us know!
Good on ya,

In the smaller commercial / institutional arena, almost everything is wye from the service entrance, though.
Just my experience...

If you're designing the heater, I think a 3-wire configuration is usually better to save the cost of running the neutral.
