Grounding of temporary power distribution box in building
Effective temporary grounding techniques must utilize a combination of grounding and bonding; grounding to clear accidental re-energization and minimize potential; bonding to ensure workers are not subjected to hazard-ous potential differences during energized situations. A temporary power distribution box (TPDB), often called a spider box, functions as a portable electrical hub that centralizes and protects power distribution on a job site. The terms. Technicians often have an “Anything Goes; It's Temporary” attitude about grounding, bonding, when dealing with the installation of temporary electrical systems and generators on construction sites, industrial facilities, special event venues, and disaster support sites. Except as specifically modified in paragraph (a) (2) of this section, all other requirements of this. extensions or alterations by unauthorized persons. Refer to the NEC for additional rules.
