GENLINK DPNL can be used in both 3-wire and 4-wire systems. For 4-wire applications where there is return neutral current
from 1-Ph loads, the DPNL must be sized for this current as well as the circulating current. For 3-wire applications where there
is no return neutral current from 1-Ph loads, a smaller size DPNL can be used. Grounding of the neutral must be done at only
one location, which is recommended to be the distribution switchboard.
Features
Inserts >40% impedance in neutral current circulating path
