    Trane makes 3 hard start kits which comprise of a cap and a potential relay..
    My scroll compressor unit calls for a 260 but the supplier gave me a 257. Claims this will work but I'm not so sure about this one. I believe the cap is OK but wouldnt the potential relay have a different voltage setting (pickup and dropout) for a scroll compressor? Any help would be appreciated.

    The 60 is used for scrolls when you get light dimming on startup. That is the primary reason for using a hard start kit on scrolls. I haven't heard of using the 57 on them but scrolls so seldom need a start kit that we've had a 60 when needed.
