Expert: Bubba Essary - 10/27/2009
Question
Is there an OSHA minimum guage/length requirement for extension cords on 1926 construction projects?
Answer
Thank you for this question.
Section 1926.405(a)(2)(ii)(J) states:
Extension cord sets used with portable electric tools and appliances shall be of three-wire type and shall be designed for hard or extra-hard usage. Flexible cords used with temporary and portable lights shall be designed for hard or extra-hard usage.
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 cord (types SJ, SJO, SJT, SJTO).
Generally, 12 guage 3 conductor extension cords are designed for hard usage - construction use. There is no length requirement I can find.
I recommend you review the NEC for more info, if needed.
I hope this helps.
