What is the British Standard number for HBC/HRC fuses?

• A. BS: 1361
• B. BS: 88
• C. BS: 3036
• D. BS: 60898

Answer: (B)

HBC/HRC fuses are high breaking capacity fuse links used to protect low-voltage circuits. The standard that governs these fuse-links in domestic and similar installations is BS 88. It defines the design, dimensions, marking, and performance requirements so the fuse links fit properly and operate safely when overcurrent occurs. In other words, BS 88 specifies the type of fuse links used in standard UK fuse boxes, which is why it’s the correct reference for HBC/HRC fuses. Other standards cover different devices or fuse families (for example, circuit breakers or other fuse formats), so they don’t apply to these particular fuse links.
