Title: Questionable on 120 VAC air conditioner
Review: After reading the great reviews on this part, I purchased the SPP6E hard start capacitor for my RV, but upon receipt it is designated for 170-277 VAC (208 or 240 VAC units). After reading all the on-line data I am concerned that it might not cut out if used on a 120 Volt AC unit and burn out the starting coil in the motor. Supco tech support does not recommend this item for 120V air conditioning systems usually found in RVs, so I returned it to Amazon without issue. Buyer beware for RV use. The SPP6, rated for 90 - 277 Volts is available at a lower cost, but uses a thermal cutout which does not have the instant restart provided by the E series.
Is the review positive or negative?
