feasible or possible.
The universal mount IQ Energy
Sentinel with provisions for
external CTs may be applied on
loads up to 4000A. They are
usually utilized for monitoring
loads larger than 400 amperes,
on power cable sizes larger
than 500 kcmil or on circuits
containing more than one
conductor per phase.
