Hi guys I have a question if I’m testing a switch with bolted 600V 400A fuses is it bad for me to use 1kv for the test? Will I damage them?

1kV should be fine for this application. You just want to watch out for any electronics or solid state components that may be tapped off the line. Use the Kohm range first to verify the circuit is clear. You could also start at a lower voltage and work your way up.
