Confused about the multitudes of plug, connector and receptacle combinations? Sintron Technology will help. The National Electrical Manufacturers Association (NEMA) has assigned designations to the various configurations. The purpose of so many different types is to prevent the wrong combinations of electrical systems from being plugged together, thereby avoiding potentially dangerous conditions.
Sintron sells the most common NEMA configurations in use in North America for 125ac and 250Vac single phase systems. This covers most residential applications.
Twist-lock devices have the advantage of locking in the mating position. This is useful in applications where the connection experiences vibration or the associated cord is hanging or subject to accidental unplugging.
