Do not install the CTs in a panel where they exceed 75% of the wiring space of any cross-sectional
area within the panel, or refer to local standards for guidance.
Do not install CTs in an area where they will block ventilation openings, or in area of breaker arc
venting.
The CTs are not suitable for Class 2 wiring methods and not intended for connection to Class 2

Secure CT and route conductors so that they do not directly contact live terminals or bus.
Perform all electrical installations in accordance with all national and local electrical codes.
