3.5 Special consideration for ground fault test

3.5.1 NEC requirements and UL standards

The National Electric Code (NEC) under Article 230-95-C requires that any ground-fault

protection system be performance tested when first installed. UL Standard 489 amd 1053

specify that instructions for ground fault testing accompany each ground fault protection

system. Please consult Instruction leaflet number IL012125EN available at www.eaton.com/

powerdefense to aid you in ground fault testing the Power Defense circuit breaker.

3.6 Maintenance mode protection

The PXR trip units support Eaton’s Arc Flash Reduction Maintenance System (ARMS), also

known as maintenance mode. When maintenance is being performed and the ARMS is

enabled, the trip unit will trip the breaker with no intentional delay whenever the configured

pickup level is exceeded. The maintenance mode protection overlays the LSI protection

functions and operates in parallel. If maintenance mode causes the circuit breaker to trip,

the “INST” indicator will be illuminated and the “Maintenance Mode Trip” message will be

displayed if the style of trip unit has a display.
The maintenance mode pickup level setting is configured using the UI or PXPM software.

They range from 2.5 (most protective) to 10, expressed as a multiplier of In. The adjustable

current settings allow for different levels of protection. A higher level may be needed when,

for example, another load fed from the ARMS protected breaker may contain motors that

are being started and create large inrush currents over the lowest trip current level. The

selection of one of the reduction settings should be determined and selected by a person

who is experienced in power system analysis.

3.6.1 Actuating and indicating maintenance mode protection

There are three ways to actuate the maintenance mode function, locally, remotely using a

contact, or remotely using communications. A blue LED on the trip unit always illuminates

to confirm when the function is enabled.
