The document is from 1944. I believe that breakers were only an innovation in the last 30-40 years. Fuses would have been used instead.

modern breakers are from the 20s, the originals are from the 1879.

I tried searching, but couldn’t find details when they became an National Electrical Code requirement. I’ve lived in a 1980s construction building where there was still a fuse box.

(Most of the results I came across were around the recent AFCI requirement for breakers in residential construction.)

Interesting. Living in Poland, I only remember seeing fuses in apartment buildings; circuit breakers started to show up everywhere only around the early 2000s.
