I am replacing an old air conditioner unit that had a NEMA 10-30P 30 Amp 250 volt receptacle with one that requires a LCDI NEMA 6-15P receptacle. The air conditioner is listed as 15 Amp 230 volt. The new 20 Amp 208 volt receptacle has two brass screws and a ground. The old receptacle is attached to black, white and red wires that run back to two separate 15 amp breakers in the box. How does the new receptacle get wired?
