Re: (ET) phenolic motor protector

["Clean Power Supply" <cleanpower att net>]

 Mike,
 Good thing you checked that. Your circuit breakers are indeed shot. Both 
sides of the disc shall be able to pull away from the contacts.  It is 
always a good idea to check them because if they don't open you may well 
burn your armature if it overloads. 
 Sincerely,
 Harold Zimmerman
