Boosters for 4 Wire Systems

 
Our Boosters for 4 wire systems are designed to maintain the proper neutral reference point in 120/240 volt single phase systems. This is essential to obtaining a constant 115 volts under varing load conditions. Boosters designed for 3 wire systems cannot be used with 4 wire systems as they can not “balance” the neutral, and therefore can not provide a constant 115 volts.
