1) Select a QO (Copper Bus) or Homeline (Aluminum bus) Load Center
2) Does the load center need to have Main Lugs or Main Breaker? (Main Lug means there is NO main disconnect) 
3) What maximum amperage rating of the load center does the application require? (For example; 100amp, 125amp, 150amp or 200amp Max. etc.) 
4) If QO, does the load center need to be a Single Phase or Three Phase load center (Homeline is ONLY available in Single Phase) 
5) How many total spaces and/or circuits does the load center need for the application? (For example; 20 full spaces with No tandem breakers or 20 spaces-40 circuits by using tandem breakers)
    Note: a Tandem breaker is one that requires One Full Pole Space, but contains Two separate circuits.
6) Does the application require a Indoor or Outdoor load center? (If Indoor and QO, will it require a Surface or Flush cover)
    Note: If Homeline is selected, ALL Homeline load centers come standard from the factory with a combination cover used for both surface or flush mount applications.
7) If QO is selected, will a Plug-On Neutral Arc Fault Breaker load center be required?
    Note: ALL Convertible mains Homeline load centers are Plug-On Neutral Design.
