2 Wire Hard Start Kit Wiring Diagram
The supco super boost is a solid state relay and hard start capacitor no loose parts or complicated wiring.
2 wire hard start kit wiring diagram. Which hard start is the best option for an rv application. Can the hard start be mounted sideways. After installing the compressor start kit place the enclosed wiring diagram on the control panel cover. Attach 1 wire to common and the other to the hermetic terminal on the run cap.
Large electric motors with a high starting torque like an air conditioner s compressor motor often use a start capacitor kit. Since supco s introduction of the 2 wire hard start kit in the late s there has been figure one 1 shows the wiring diagram for the oem style. Figure two 2 shows the wiring diagram for a 2 wire hard start. Kickstart hard starts are the only pre assembled 2 wire easy to install starting devices that utilize the superior sensing capability of a potential relay in combination with a start capacitor.
Connect the yellow wire to the compressor capacitor terminal marked c or common. Your ac unit is getting old. A start capacitor kit contains a start capacitor relay and wires. Just wire it across your run capacitor as shown below.
Figure 2 2 wire connection two wire hard start kits are connected in parallel with the run capacitor for permanent split capacitor psc type compressors. These devices work on all 1 5 hp single phase 208v 230v 265v air conditioning heat pump and refrigeration compressors reciprocating scroll. And connected to the start and run terminals on the compressor for capacitor start induction run csir type compressors. No hard starts should always be upright.
Here are some of the reasons why you might need to put one in. The start capacitor gives the motor s windings an electric boost during the start up phase. Are the wire leads polarity sensitive.
