208V/230V Single Phase Marking on Daikin Equipment

[DJordan23]

Can someone give me some more clarity on what this means in terms of allowable voltage on a piece of single phase equipment?

The factory says that it can't run on 240V single phase so what is the point of indicating the 230V?

That is all...
Thanks!

Is it possible that this equipment is available in other countries, ones that have 230V single phase?

You spoke to wrong person at the factory.

it can run on either 2 lines of 208/120 or on a 120/240 single phase supply. Most AC/refrigeration equipment is that way.

What is odd and I find frustrating is the cutsheet gives the capacity at 240V. Maybe this is a common practice that I am not aware of yet.

Thanks I am pushing back to get more information

Most those countries "nominal voltage" is 240 volts these days.

I'd say it has 4.75 kW @240 volt heat strip in it. If used on a 208 supply the kW will be approximately 75% of that. blower motors or compressors will still work on 208 supply but will draw a little more current than they would on 240 volts. Either way they should not draw more than nameplate ratings though

I agree with you kwired. I got hoodwinked on a 240V high leg service. My panel in question is 240V single phase in a light commercial building. Hoping I can still install the furnace without a buck transformer.

I see no reason this can't go on single phase or high leg three phase system, other than breakers would need to be straight 240 volt breakers instead of 120/240 "slash rated" breakers. Keep off the high leg and you still have no issues.

This might help to explain.

Agree with Kwired. You talked to someone that doesn’t know.
NEMA 230V +-10%
230+23=253V
230-23=207V
