Rooftop Unit Nameplate Voltage 208/230 (3-phase), system voltage 240 (3-phase).
Reefer man says it's OK.
Which voltage (208, or 230) do you use to dedermine 10% tolarance level?
I know we've been her before, but what was the final verdict.

Deja Vu?

You use them both ...90% of 208 for the minimum, 10% of the 230 for the max.

Thanks, Reno!

I was thinking the same thing, but I thought there was a previous link that discussed the issue.
