Fuses & Fuseholders Q & A
Q: How often should fuses be replaced?
A: Only when blown - quality fuses last years under normal conditions.
Q: Can I use a higher amp fuse temporarily?
A: Never - this defeats the protective purpose and risks equipment damage.
Q: What's the difference between ceramic and glass fuses?
A: Ceramic handles higher temperatures; glass allows visual inspection.
Q: Are Chinese fuses reliable for critical applications?
A: Yes, when sourced from certified manufacturers meeting international standards.
Q: How do I identify a quality fuseholder?
A: Look for thick metal contacts, secure mounting, and flame-retardant materials.
