This video is part of the heating and cooling series of training videos made to accompany my websites. Potential starting relays consist of a high resistance coil and a set of normally closed contacts. Explaining the differences between current relays and potential relays and their role in starting compressors.
This is the first one on the potential start relay.
These relays meet all requirements for original equipment relays. Terminals 4 and 6 are used for capacitors and or condenser fan connections and have no electrical significance to the starting relay itself as shown in. The coil is wired between terminals 2 and 5 with the contacts between terminals 1 and 2. Packard gives you the knowledge you need for success on the job.
