When installing an AVT, care should be taken to ensure that sensor leads used to connect the AVT to the line
or bus and to ground shall not be any longer than necessary and shall be routed to avoid sharp edges, pinch
points or mechanical damage. Do not extend the sensor leads with a splice that exceeds the overall conductor
length of 10 feet from the isolation module to the sensor lead tap termination (to comply with NEC tap rule,
the AVT can be treated as a feeder circuit per NEC article 240.21 (B) (1) (b) exception. This rule allows a tap of
no more than 10 feet on a feeder circuit without the need for overcurrent protection).
Secure the sensor leads to the power conductor or another nearby rigid feature to prevent movement of the
sensor lead in the event that the termination point failed. Sensor leads can be secured using cable ties,
clamps, mounts, or tape. The sensor leads should be secured at multiple locations, including near the
termination point. (see the diagram below)
In addition, the sensor lead terminations should be inspected periodically, like other critical terminations
inside an electrical enclosure, to ensure they are tight, and the sensor leads are secure.
Always insulate the sensor lead termination points. A variety of methods can be used to insulate the
termination. Some connectors have insulating housings, others have accessories to insulate the connector.
Insulating tape or heat shrink can also be used.
Use approved connection methods and follow local codes and standards when terminating the sensor leads.
