CEPS-A GFCI Troubleshooting  

If the GFCI on the blue inverter is tripping, there are two things that can 
cause this: a crossed neutral (dangerous) or inrush current (not 
dangerous).  This simple test will help you to determine which it is.  

#1)  Get an amp/current meter 

#2)  Measure the red OUTPUT wire coming out of the inverter.  Write 
down how many amps________ 

Measure the white/red stripe OUTPUT wire coming out of the inverter.  
Write down how many amps_________ 

#3)  The two amp readings should be equal (within 0.1A preferred).  If it 
is equal and GFCI still strips, proceed to step #4.  If it is not equal, there 
is a problem with your output neutral wiring.  It needs to be a 
dedicated neutral wire going out to your lights and cannot touch the 
building neutral anywhere.  Usually one of the emergency fixtures in 
the field has been incorrectly connected to a normal building neutral 
wire.  As a result, some of your neutral current is returning to your 
building neutral instead of your inverter neutral.  This is a code issue 
and if the imbalance is large enough it can also damage the inverter.   

#4)  If the currents are balanced please call tech support at 1-800-982-
4587 and reference this troubleshooting guide, they will assist with 
next steps.
