Does this level of protection by default require that electrical manholes are now permit entry confined spaces?
The electrical hazard associated with cable inspection and the possibility of limited or contaminated air in a manhole is not related. The NFPA 70E tables are default conditions based on the experience of the Technical Committee. I believe that a manhole (which a person enters) is a confined space as defined in the OSHA standards. However, I am not an expert on hazards associated with confined spaces.
