Extend thermal visibility across the busway power path

Eaton Exertherm’s bus duct thermal monitoring solution provides continuous visibility of critical busway joints and connections. The tap-off and end feed box thermal monitoring solution extends that same thermal monitoring capability to the additional high-risk interfaces where power is transferred from the busway system to downstream loads.

Tap-off boxes and end feed boxes contain cable-to-busbar terminations, breaker interfaces and power connections that can be affected by vibration, thermal cycling, ageing components and mechanical stress. These conditions can increase resistance, create abnormal heating and lead to unplanned outages if left undetected.

This solution is a fit if:

You already monitor bus duct joints and want to extend visibility further along the power distribution path
Tap-offs distribute power to critical equipment, zones or downstream loads
Power is drawn from busway systems at multiple connection points
Failure at load interfaces would disrupt operations
Visibility into connection health is limited between inspections
Reducing personnel exposure to energized components is a priority

What is monitored in tap-off and end feed boxes?

The tap-off and end feed box thermal monitoring solution enables continuous temperature monitoring of critical interfaces where power is transferred from the busway system to downstream loads such as server racks, power distribution units and distribution panels.

Benefits of the tap-off and end feed box monitoring solution

Safer maintenance practices

Reduce unnecessary interaction with energized assets during inspection and fault investigation activities.

Continuous visibility of critical load connections

Monitor cable-to-busbar interfaces and power terminations continuously rather than relying solely on periodic inspection cycles.

Extends existing bus duct monitoring capability

Expand thermal visibility beyond bus duct joints and connections to include the tap-off and end feed box interfaces that support reliable power delivery to downstream loads.

Earlier identification of developing faults

Detect abnormal thermal conditions before they escalate into failures, downtime or equipment damage.

Improved power distribution reliability

Maintain greater visibility across the critical connection points supplying downstream loads.

Features of the tap-off and end feed box monitoring solution

Ready-to-install kit architecture

Supplied as a ready-to-install kit for each tap-off or end feed box, helping simplify deployment across new-build and retrofit applications.

Continuous, maintenance-free monitoring

Provides 24/7 thermal visibility of critical power transfer connections through a fit-and-forget architecture that operates without routine maintenance.

OEM-neutral deployment across busway systems

Designed for tap-off boxes and end feed boxes regardless of the manufacturer, enabling a consistent monitoring approach across mixed busway environments.

Integrated alarm and data connectivity

Supports local and remote alarm notification while integrating with SCADA, EPMS, BMS and Modbus-based monitoring platforms.

A more complete approach to busway thermal monitoring

Together, the Eaton Exertherm bus duct thermal monitoring solution and tap-off and end feed box monitoring solution provide a more complete approach to monitoring busway infrastructure. By extending continuous thermal monitoring beyond the bus duct itself, operators can identify thermal issues sooner, reduce operational risk and maintain continuity of power to critical loads.
