First off, this is my first post. Great forum!
I have been surfing the site for the answer to this exact question, and while I have come close, I did not find exactly what I was looking for. I have been reviewing OSHA 1910.303 and NFPA 70e for the answer to this question as well. So here is the question:
1) Will screens around energized parts >50V inside control cabinets be suitable to protect employees from accidental contact?
According to OSHA 1910.303 (g) (2) the answer is "yes", as long as the screens inside the control cabinet are permanent, fully enclose energized parts >50V and prevent accidental contact.[/ , 2) but do you guys agree? 3) Am I interprating this correctly?
Guarding of live parts.
1910.303(g)(2)(i)
Except as elsewhere required or permitted by this standard, live parts of electric equipment operating at 50 volts or more shall be guarded against accidental contact by use of approved cabinets or other forms of approved enclosures or by any of the following means:
1910.303(g)(2)(i)(B)
By suitable permanent, substantial partitions or screens so arranged so that only qualified persons will have access to the space within reach of the live parts. Any openings in such partitions or screens shall be so sized and located that persons are not likely to come into accidental contact with the live parts or to bring conducting objects into contact with them;I]
