My boss bought a replacement compressor for 277volt powered water source heat pump. When he opened the special ordered box, the compressor was 230v. The supply house told him that was the right one and that he just had to change the capacitor.

What do you think?

Any advice appreciated.

We're going to need a model # on this one.

Personally I doubt it.

Is that the compressor #

Here are the specs for that compressor.
Trane, American Standard 1.7 HP, 208-230V, 1 PH, 19,000 BTU, R410A, Hermetic (Reciprocating) Compressor Replacement"

I can't see that working with 277 VAC. 264.5 VAC would be the standard max service amperage.

Although the one you replaced had the same 230 VAC SPEC.

I assume you mean voltage

Yes, sorry it's been a long day. Duh.

Yes it has

277 volts has to be 3 phase in anything I ever saw. Can't believe it will work.

The high or stinger leg of 480 is single phase. Common in NYC for lighting.
