Interesting how it suggests fuses (proper ones, not rewireable) protect so much better than mechanical circuit breakers.
HRC (High Rupturing Capacity) Fuses have a lot higher capacity than circuit-breakers, as far as High Energy Faults go.
Where as a Circuit-Breaker will interrupt "destructively" under Fault-Arc conditions, a Fuse package by design, will contain the entire arc within itself.
With the use of fine Silica sand, it forms glass under the heated conditions.
A lot better insulator.
Anyone else got any comments on this document?.
