Panelboard Terminals
Refer to panelboard manufacturer’s documentation for detailed installation instructions. General
recommendations:
•
Tightening torque for line, neutral and equipment ground terminal
•
Hardware torque values
Refer to circuit breaker documentation for allowable wire temperature rating, wire size and tightening torque.
•
CT wire routing
Every CT has an internal protective resistor which allows for safe voltages across all the CTs even when the
secondary is opened.
The CT Strip Assemblies are designed to sense branch currents from panelboards. The
power wire from each branch circuit breaker will pass through a CT (with 1 turn) on the CT Strip Assembly. A
secondary sensing signal is brought to the PowerView Module via the wire harnesses.
Type and AWG of CT Load Wire: All 8AWG & THHN 6AWG (or Equivalent)
