    Limited Approach Boundary for 35kV switchgear

    10. What is the Limited Approach Boundary for a 35kV switchgear?
    Your Answer: 10 feet
    Help: NFPA 70E Table 130.4(D)(a)
    NFPA 70E Arc Flash and Shock Hazard Boundaries Explained

    This question was marked incorrect, when in fact it is 10 feet for the limited approach boundary for 35 kV, the link that is attached to the question marked incorrect takes you to the table that shows the 10 foot boundary. Please correct this as otherwise we don't know which answers are correct and incorrect. I noticed one other that is wrong pertaining to in line splicing that I am very knowledgeable in that area.

    No, its correct at 5 ft, 10 ft is for movable conductors and 5ft for fixed circuit parts. Since we are talking about switchgear, this means fixed circuit parts.

    Thank you, I stand corrected, sorry for the mistake, but also looking at the table for 35kV it should be 6 feet not 5.

    Sorry, I just finished the NETA III practice exam and was asked about 15kV, and made a similar mistake as you did.

    I'm thinking the answer is (6 ft 0 in) since the switchgear is fixed circuit part.
