I found a 20 amp ceramic fuse to test the PD9280.
Connected the black (hot) and white (neutral) to an AC two prong plug, (left the green ground disconnected), and the fuse blew.
The only difference is when the PD9280 was installed the black, white and green wires were connected to the correct connections of hot, neutral and ground from the AC dist panel.
I only tested using using hot and neutral wires and didn't check to see if the black and white were connected to hot and neutral from AC.
I'm wondering if I should test again using a three prong AC plug connected to their respective wires, black (hot), white (neutral) and green (ground) from the AC?
