    GFCI Protection of Drinking Water Coolers

    PCinspector1, I think the 'readily accessible' requirement was added in 2011.

    GFCI Protection of Drinking Water Coolers

    ADAguy, I do think we are speaking about different things. The NEC definitions of accessible and readily accessible are quite different than the ICC definitions of accessible. I was commenting on the original post regarding GFCI protection and the 'readily accessible' requirement of 210.8 in...

    GFCI Protection of Drinking Water Coolers

    Good/Bad.....Right/Wrong.....Like it or not, according to the NEC, the 'Readily accessible' term has the same meaning weather applied to GFCI protection devices or service disconnecting means. Would you allow a service disconnect behind/underneath the drinking fountain? Just asking.

    Electrical Service Approval

    Unable to approve this service as submitted, more detail is needed. It appears that service conductors to the main switch and feeders from the main switch are sharing the same 'New Wireway', this is not permitted per NEC 230.7.

    A Glimpse Into A Rare Electrical Sighting

    It appears that I took too long before hitting the 'post reply' button. Don't think I can edit my previous post.

    A Glimpse Into A Rare Electrical Sighting

    I disagree. The grounded conductor is required to be routed with the ungrounded conductors to each service disconnecting means. (250.24(C)) The gray conductor is neither ran with, nor terminated at the service disconnecting means. The switch on the right.

    What's Wrong with this Diagram?

    Sorry, I didn't finish my thought. NEC 250.24(A) requires the grounding electrode conductor to be connected to the grounded service conductor at the service, not in a sub-panel.

    What's Wrong with this Diagram?

    This took longer than I thought it would. I kept wondering why we were upsizing one of the sets of feeders to 125 amps, and I couldn't understand.

    Goodbye 6 Disconnect Rule in NEC 2020

    I wonder what the reasoning is for this and does it apply to feeders as well?

    Mounting a dry -type transformer in a ceiling

    As previously stated the disconnecting means is required to be "in sight of the transformer or in a remote location." The 'remote location' portion has some additional requirements such as labeling and lockable. We need to keep in mind that the required overcurrent protection of the secondary...

    110.26(C) Entrance to and Egress from Working Space

    The problem could be solved by simply removing the door, as long as there is no separation required between the rooms.

    110.26(C) Entrance to and Egress from Working Space

    The door between the two electric rooms is the item in question. This door meets the requirements of 110.26(C)(3) for the south electric room, but is in violation for the north emergency electric room. The door does not open in the direction of egress.

    Sizing a supply side or main bond with parallel conductors

    Thank you, I enjoy the opportunity to add to the discussion.

    110.26(C) Entrance to and Egress from Working Space

    In my opinion this setup would meet the requirements of 110.26(C)(1) and 110.26(C)(2), but not 110.26(C)(3). (C)(3) requires that "Where equipment rated 800A or more....and there is a personnel door....the door shall open in the direction of egress and be equipped with listed panic hardware."...

    Sizing a supply side or main bond with parallel conductors

    Maybe start at Table 8 of Chapter 9 and find that #3/0 wire is 167800 circular mils, times two is 335600 circular mils. Now back to table 250.102(C)(1) and find that the supply side bonding jumper needs to be #2 copper or #1/0 aluminum.

    NEC Code Quiz

    250.24(B) in the 2014 NEC tells us that the equipment grounding conductor, the grounded conductor and the service disconnect enclosure shall be bonded together "within the enclosure for each service disconnect in accordance with 250.28."

    Electrical Violation Thread NEC

    I can't tell for sure, but it looks as though the neutral buss is connected to the enclosure through the black wire on the left side. Not permitted in a sub-panel.

    Can you do this?

    I hope the answer is residential. I assumed it was residential. If not residential, my previous posts are embarrassing.

    Can you do this?

    Yes, #4 is good for 85 amps. But without knowing what the connected loads are, the conductors on the line side of the meter can exceed 120 amps and is not permitted.
  20. L

    Can you do this?

    Another issue...yes, as service conductors and feeders are not permitted in the same raceway. Also, I think a set of load calculations are in order as there may be over 100 amps of load being carried on service conductors rated at 100 amps.
  21. L

    Can you do this?

    More than one service disconnect is permitted, NEC 230.71; however an indoor and an outdoor service disconnect does not meet the grouping requirements of NEC 230.72.

    Bundling NM cable (Romex) in conduit

    My thoughts for the original post lead me to 310.15(B)(3), more than three current carrying conductors in a cable or raceway, longer than 24", and then to Table 310.15(B)(3)(a). It looks to me as though we have between 10 and 20 current carrying conductors in the raceway, thus a 50% capacity of...

    A floor receptacle is another option to meet this requirement.

    Would a double pole GFCI Breaker trip if .........

    I am not sure I can answer your question but; Last week I called out required GFCI protection for a temporary 120 volt, 30 amp receptacle. The contractor replied that Square D does not make a Homeline, single pole, 30 amp GFCI breaker. A quick computer search took me to Schneider Electric's...

    It is not often you find a disconnect like this

    For starters, I would say, 'You can't switch a neutral.' 404.2(B) Schucks, in this case it is permissible. Exception to 404.2(B) Next I would go with, 'You can't put an overcurrent device in the neutral.' 240.22 That one sticks. What? You say that is not a neutral. 'Please...
