Product FAQs
8 answersDoes this breaker fit into a standard Eaton BR or CH load center?
No, the GHQRSP2020 is a specialized bolt-on miniature circuit breaker designed exclusively for Eaton Pow-R-Command and Pow-R-Line commercial panelboards. It will not fit in standard residential BR or CH load centers.
Are standard branch breakers allowed in the same panelboard as the GHQRSP2020?
Yes, Pow-R-Command panelboards support mixing standard non-controllable branch breakers, such as the standard GHQ or GHB series, alongside controllable GHQRSP breakers within the same chassis.
How does the remote switching function operate on the GHQRSP2020?
It features a factory-installed 24VAC solenoid operator that receives low-voltage signals from the Pow-R-Command controller to switch the circuit on or off automatically, eliminating the need for external lighting contactors or relays.
Where do the control wires for the internal solenoid connect during installation?
The low-voltage solenoid control leads connect directly to the panelboard's Breaker Control Bus (BCB) or Breaker Termination Board (BTB), which links the breaker to the main intelligent controller.
Can I substitute a standard GHQ2020 for the GHQRSP2020?
No. While they share the same physical footprint and thermal-magnetic overcurrent ratings, the GHQRSP2020 includes a 24VAC remote control solenoid. The standard GHQ2020 is a manual-only breaker without automated switching capabilities.
Is the GHQRSP2020 rated for High-Intensity Discharge (HID) lighting circuits?
Yes, the GHQRSP2020 carries an HID rating, making it strictly approved for switching and protecting high-intensity discharge lighting loads as well as standard fluorescent applications.
Does the GHQRSP2020 include a manual override for maintenance?
Yes, Pow-R-Command controllable circuit breakers feature a mechanical status flag and a manual override function. This allows electricians to manually switch or lock out the circuit for safe maintenance without waiting for automated controller input.
Which generations of Pow-R-Command systems are compatible with this breaker?
The GHQRSP2020 is compatible with several generations of the Pow-R-Command lighting control system, including the PRC25, PRC750, PRC1000, PRC1500, and PRC2000 controller series.
