The PowerStay™ Power Center is a combined indoor/outdoor transfer switch and distribution panel.  It can be used as service entrance 
equipment for 60 Amp, 100 Amp and 200 Amp services.  In addition to being a transfer switch, the Power Center adds additional circuits for 
outdoor applications such as air conditioner compressors, sewage lift pumps, boat docks, outbuildings, garages, pump houses, barns and the like.  
The 200 amp series models will accommodate 12 single pole circuits, and the 60 amp and 100 amp series models will accommodate 16 single 
pole circuits. 
 
The Power Center is made up of five basic elements: 

1.  Utility Main Breaker 
2.  Generator Main Breaker 
3.  A 20, 30 or 50 amp 125/250 volt inlet prewired to the generator breaker 
4.  A mechanical safety interlock that prevents both Mains from being “ON” at the same time 
5.  A set of sub-feed lugs to handle cable up to 4/0 AWG to feed the house Main panel. 

 
 
CAUTION:  If the PowerStay™ Power Center is used as the main service disconnect, it is imperative that all circuit breakers in the Power Center 
AND the Main load center in the house be turned OFF when running the system from the generator.  Then, turn on only the breakers that the 
generator can handle at any one time.  Check the generator “continuous” wattage rating to determine the total wattage of connected load.  It 
may be necessary as well as desirable to turn On and Off different loads/breakers as needed during an actual power outage. 
 
 
 

1.  Power Center can be installed above, below or on either side of the utility meter socket.  However, the preferred location is to the RIGHT of 

the meter socket since the location of the lugs for the Utility Main are on the Left side of the Power Center.  Knockouts (KO) are provided 
only in the bottom of the enclosure.  However, since the enclosure is aluminum, it is easy to cut in the desired knockout.  If the KO is cut in 
above the live terminals of the circuit breakers, a watertight hub should be used.  NOTE:  If a 2” KO is cut in the side of the Power Center 
enclosure, the dead front panel may need to be “notched” to clear the 2” fittings.  The back of the KO must be 3/8” from the rear of the 
enclosure. 

 
2.  Loosen the thumb screw from the cover of the Power Center, and slide the cover down to remove.  
 
3.  Remove the two screws from the bottom of the dead front.  On the 200 amp models, remove the two Nylok nuts securing the interlock 

mechanism.  When the cover is pulled forward, the snap-in circuit breaker will fall out.  Set the front cover and dead front aside for 
reinstallation after wiring. 

 
4.  The mounting holes in the back of the Power Center are on 16” centers so they could line up on your studs if desired.  Use all four holes to 

mount the enclosure. 

 
5.  On 200 amp models, select the bottom center 2” KO to exit to the Main distribution panel.  On the lower amperage Power Center models, 

use one of the smaller KOs to exit.  Terminate the LOAD wires in the landing lugs on the bottom of the bus assembly, one of the Neutral lugs 
and the Ground lug on the right side of the enclosure. 

 
6.  Terminate wires from the meter socket into the utility Main breaker on the left side, and the Neutral into the unused lug on the insulated 

neutral bar. 

 
7.  Plug in and wire any additional circuit breakers in the spaces provided.  Installer will need to remove any hold-down strap to insert additional 

circuit breakers.  Re-install hold-down strap after breakers are inserted. 

 
8.  Reinstall dead front cover and interlock mechanism if removed earlier.  Fill any unused spaces in the dead front with the closing plates 

provided. 

 
9.  Reinstall cover.
