Can you replace a 50 amp contactor with a 40 amp contactor?
Replacing a 50 amp contactor with a 40 amp contactor is not advisable, as the 40 amp contactor may not be able to handle the load safely. This could lead to overheating, failure of the contactor, or potential damage to the connected equipment. It's essential to match the contactor's rating to the load requirements for safe and reliable operation. Always consult with a qualified electrician for such replacements.

A definite purpose contactor is designed (and rated) for a specific load. So a lighting contactor is one example of a definite purpose contactor. A motor starter contactor is another example. So, a lighting contactor is a definite purpose contactor, but a definite purpose contactor is not necessarily a lighting contactor (it might be a motor starter, for instance).

If you have a bad compressor does that mean you need a new contactor?
Not always. But if a compressor goes bad it can take out the contactor. I have replaced compressors before and found the contactor is still ok. In a commercial application Copeland will not honor the warranty if the contactor is not replaced at the same time a new compressor is installed. Not sure about residential but for a $15 contactor I would not gamble with it.
