I've measured the surge at ~15mA, which exceeds the 5mA GFI outlet by quite a lot. 5mA is the current residential GFI standard in the US. Milwaukee Instruments confirmed that a 15 - 20mA surge is not uncommon when the solenoid switches on. The only solution I've found for this would be to install a datacenter 100mA or commercial 30mA outlet.
