How do you check 220v buss fuse?

To check a 220V bus fuse, first ensure the power is turned off at the circuit breaker to prevent electrical shock. Use a multimeter set to the continuity or resistance setting, and touch the probes to the terminals of the fuse. If the multimeter beeps or shows a low resistance reading, the fuse is good; if it shows no continuity, the fuse is blown and needs to be replaced. Always follow safety precautions and consider consulting a qualified electrician if you're unsure.
