PowerGATE™ Power Input / Output Panel
Installation
- Input / Output Panels (continued)
(For Output Panels continue to page 9)
Step 3: Wiring the Bus Bars
WARNING
Ensure circuit breakers are OFF and the transfer switch is
locked out from utility power prior to connection.
Failure to install transfer switch will create the potential
for the generator to energize utility lines and endanger
utility personnel. Conversely, utility lines may energize the
PowerGATE™ Input Panel and endanger generator personnel.
The PowerGATE™ Input Panel is for use only for
connection of a generator to the source terminals of a
transfer switch, such that the inlets are only energized
from the generator.
1. Secure ring terminals on ends of cable
– The recommended input (contractor direct wire) wire
gauge for this unit is 350 MCM
– Terminal crimp rings to have 1/2" opening
2. Secure ring terminals to bus bar
– Use 1/2" bolts tightened to ninety-eight (98) foot pounds
of torque
3. Secure a solid and permanent electrical ground between the
building ground point and the PowerGATE Power Input Panel
NOTE: Conduit shall NOT be relied upon to provide grounding
protection to tap box
4. Vacuum entire upper chamber to ensure no metal shavings
are left behind
WARNING
Three phase power systems consist of three phase or hot
conductors that are shifted by 120 degrees. Three phase
loads such as motors may only work properly if the phases
are connected in the correct order. Some motors may work
with connected improperly, but will operate backwards.
Utility power and electrical generators may be wired either in
a clockwise or counter-clockwise order. It is important that
any generator connected to the PowerGATE™ Input Panel
is connected in the same rotation (clockwise or counter-
clockwise) as the utility power.

Step 4: Determine Phase Rotation
This information will be needed when connecting a generator.
A: Determine phase rotation of the utility power
– Connect a phase rotation meter to a three phase power
source in the building and record whether the building is
wired clockwise or counter-clockwise
B: Apply the provided label (Figure 8) to the inside of the
PowerGATE™ Input Panel on the inside of the cam
connection chamber door (Figure 9).

Step 5: Conduct a safety test to ensure proper installation
Do not attempt to use the PowerGATE™ Input Panel prior to
installation and completing the Pre-Operation and Maintenance
Checklist under Appendix A.
