Yes, a GFI system is right for protecting you, but how about that assembly you are repairing? If that circuit breaker is set at 10 Amps at 120 Volts you can create 1,200 watts of smoke and flame before it kicks in.
One solution is a variable and isolated AC power source with adjustable current limiting. Nice to have but expensive.
Another choice is a power supply with a current limiting set just above the expected value. You can design it with current limiting so that some power is still applied to the repair item for troubleshooting purposes. Or you can build it as an electronic circuit breaker that shuts off power.
