Max current on the power rail of protoboard PCb

[martian]

I have one of these Adafruit Perma-Proto Half-sized Breadboard PCB and am wondering how much current ( at 5V) is safe to carry on the power rails?

I usually try to keep it under 2A. If I need more than that, I solder some wire to run in parallel to the trace.
