Transfer Switch Contactors
Are the individual contactors inside the transfer switch replaceable? And does a 50 amp system use 220v contactors? Are they difficult to replace? thanks, Ron

Both contactors will be three pole, normally open contacts. The contacts must be rated at least 50 amps. The coil voltage will be determined by the type of transfer switch you have. Some may be 120v, and some may be 24v. It will say the voltage on the old coil. Replace it with the same voltage. The typical contactors will be what is known as "IEC" style as opposed to "NEMA" style. It would be difficult to find one that isn't rated with a high enough voltage on the contacts. The highest voltage you will see at the contacts is 120v to ground.
