Product Overview
A fail-safe transfer switch takes two power feeds and moves its outlets to the second feed when the first one drops, so single-corded gear keeps running through a feed loss. Its front label warns that both inputs must be phase and polarity synchronized. A rear module carries the network jacks and two jacks marked T/H1 and T/H2.
