2 Wire Hard Start Kit Wiring Diagram

If you need some help with it in this video i show you how to install and wire a spp6 hard start kit.

2 wire hard start kit wiring diagram. And connected to the start and run terminals on the compressor for capacitor start induction run csir type compressors. Figure two 2 shows the wiring diagram for a 2 wire hard start. These devices work on all 1 5 hp single phase 208v 230v 265v air conditioning heat pump and refrigeration compressors reciprocating scroll. The start capacitor gives the motor s windings an electric boost during the start up phase.

Which hard start is the best option for an rv application. Here are some of the reasons why you might need to put one in. A start capacitor kit contains a start capacitor relay and wires. 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.

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. Just wire it across your run capacitor as shown below. The supco super boost is a solid state relay and hard start capacitor no loose parts or complicated wiring. Route the starting kit wires along the side of the existing wiring and tie wrap all of the wires together with the tie wrap provided.

Spp6 is typically recommended for rv hard start kits. Large electric motors with a high starting torque like an air conditioner s compressor motor often use a start capacitor kit. No hard starts should always be upright. Attach 1 wire to common and the other to the hermetic terminal on the run cap.

Connect the yellow wire to the compressor capacitor terminal marked c or common. 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. Are the wire leads polarity sensitive.
