Construction electrical standards
Subpart K covers electrical work in construction, from 1926.400 through 1926.449. The hard part is rarely the content. It is working out whether what you are doing counts as construction in the first place.
Maintenance or construction
The same crew, in the same building, on the same equipment, can fall under general industry one week and construction the next depending on the nature of the work. Replacing a failed component like for like tends to be maintenance. Altering, extending or installing tends to be construction. Sites get this wrong in both directions, and the answer changes which standard an inspector cites.
What it covers
Installation safety requirements, safety-related work practices, safety-related maintenance and environmental considerations, and requirements for special equipment. Temporary wiring gets specific attention, because temporary is where construction sites accumulate risk.
Ground fault protection
Construction sites carry a duty around ground fault protection that general industry does not frame the same way, generally satisfied either through GFCI protection or a documented assured equipment grounding conductor programme with someone competent designated to run it. Several state plans add their own requirements on top.
Training
The qualified and unqualified distinction carries across from general industry, along with approach limits for unqualified persons working near overhead lines.
