After thorough cleaning and inspection, if the
megohm reading is still low, it may still be safe to
energize the equipment. When restoring flooded
or wet equipment to service, for example, the
accepted practice is to require a minimum of 1
megohm before energizing. Under damp or
humid conditions, it is considered good practice
to operate the equipment at lower-than-rated
voltage for a short time, if possible, to improve
the low reading.
Instructions for inspection and testing of low-
voltage power circuit breakers are given in the
individual instruction manuals provided with each
circuit breaker. Directions for testing devices such
as relays, instruments, and meters are found in the
instruction manual furnished with each device.
Protective relays must be coordinated with other
relays in the system; therefore, these relays are set
by the purchaser. General instructions on setting
relays are provided in the relay instruction manuals.
The equipment should be energized in sequence by
first energizing the main devices, then the feeder
devices, and finally the branch-circuit devices.
Turn each device on with a firm positive motion.
Arcing energy reduction functions
Per the NEC clause, 240.87, when the circuit
rating is 1200A or higher, an arc energy reduction
function is required.
For field commissioning of the Reduced Energy
Let-through (RELT) function reference the Arc flash
energy reduction using second I Protection (2I)
document 1SDC007114G0201. For field testing of
the RELT function:
• Step 1: Test position
Turn the RELT switch to the "TEST" position.
Observations to be made:
1. Pilot lamp will glow
2. Switch will return to the "NORMAL" state
and the Pilot lamp will turn off
• Step 2: ON position
Turn the RELT switch to "ON" position.
Observations to be made:
1. Pilot lamp will glow
2. Switch will remain in "ON" position
3. At the same time, the breaker trip unit will keep
flashing "2I Protection Active"
• Step 3: Normal position
Turn the RELT switch back to "NORMAL" position.
Observations to be made:
1. Pilot lamp will keep glowing for 15 seconds and
at that point there will not by any indication on
the breaker trip unit
For any other energy reduction solutions, consult
factory. To test and commission these features, see
project documentation for specific operation and
behavior.
