Where should the grounding of the construction site s electrical distribution box be connected
Although the grounded conductor is connected on the supply side, it shall not be connected to the EGCs or reconnected to ground on the load side of the service disconnection means except as otherwise permitted in the 2017 NEC Article 250. A grounding terminal or grounding-type device on a receptacle, cord connector, or attachment plug shall not be used for purposes other than grounding. Branch circuits - Ground-fault protection - General. The employer shall use either ground fault circuit interrupters as specified in paragraph (b). This subpart addresses electrical safety requirements that are necessary for the practical safeguarding of employees involved in construction work and is divided into four major divisions and applicable definitions as follows: (a) Installation safety requirements. In an airplane, for example, the fuselage acts as the ground. Paragraph (d) of this section also applies to protective grounding of other equipment as required elsewhere in this Subpart.

Connecting the construction site s flexible cord to the distribution box
Splicing flexible cords is generally prohibited. Note: The National Electrical Code, ANSI/NFPA 70, in Article 400, Table 400-4, lists various types of flexible cords, some of which are noted as being designed for hard or extra-hard usage. Examples of these types of flexible cords include hard service cord (types S, ST, SO, STO) and junior hard service. Whether you need an industrial portable power station, a complete jobsite power station, or help managing temporary wiring and distribution, this will help you stay compliant with all the necessary requirements. Temporary power systems tend to be exposed to harsh environments and frequent use. 405 (a)2 (ii) (H) specifies that it's okay to run extension cords through doorways and “pinch points,” but only if they're protected from damage — which the standard says they must be in all cases, anyway.
