Replaced 15v outlet with another basic one. All seemed to go well during install, but after it was over, the gfci outlet trips when I place a reasonable load to it.
When left alone, power flows though the outlet to the rest of the devices. When I plug a lamp in it, it's fine. When I plug my surge protector in it with only a modem and router on it, it trips. It was on the old outlet.
When it trips, it's only the gfci before it and everything before gfci works when tripped.
There are four main wires. Two white and two black. Then my green ground. I placed two live wires on top. On mine, it didn't really specify where so I left as old ones in the past. It did say the white and black side. I did separate and verify ground was on top to make sure.
Any help would be great!
