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.

What causes an electrical contactor to make a buzzing noise when activated and what should be done about it?
Contactor chatter can be caused by a broken shading ring winding on the pole face of the contactor. Low voltage to the coil can be another reason for contactor chatter. A constant hum on a contactor will be caused by misalignment to the two pole faces. Check for rust building up on the two surfaces.
