Wiring Standards for Temporary Power Distribution Boxes
To ensure worker safety, the Occupational Safety and Health Administration (OSHA) has created standard 1926. This standard regulates safe work practices for dealing with temporary wiring. The provisions of this paragraph do not apply to conductors which form an integral part of equipment such as motors, controllers, motor control centers and like equipment. A safe, eficient temporary wiring system protects the client, the employer and the em-ployee by minimizing ser ous injuries, fires, pow-er failures and downtime. So, to help clear this up, this week we're explaining more about this regulation, what temporary installations can involve, and how you can ensure that your circuits stay safe and within the required standards. Whether you need an industrial portable power station, a complete jobsite power station, or help managing temporary wiring. Learn what OSHA requires for temporary wiring on construction sites, from grounding and GFCI protection to overhead clearances and employer liability.
