    While it is not done, I agree that the word "maintained" requires some physical method be used to maintain the space between the conductors or cables. Just the fact that there is space is not enough...

    The language in the IRC is much like that in the NEC. It can be complied with without the use of 3 way switches.

    While 3-ways are typically installed to comply with 210.70(A)(2)(3), there are other methods that could be used to comply with that section. As others have said, there is no requirement in the NEC...

    One code cycle, I think in the 90s, had underground duct bank ampacities for under 600 volt systems. They were put in the code with an effective date of 3 years later. The action on the next code...

    It appears to me that the conductor in question would be a supply side bonding jumper and not an EGC. If that is the case the conductor in each raceway would only need to be a 1/0. See 250.102 and...

    "CE" is not a listing. A "listing" requires a third party evaluation. CE is a manufacturer's self evaluation.

    In general, my opinion it that insulation tests for under 600 volt systems are worthless unless the conduit is wet or contaminated. If there is bare copper, it will pass the megger test unless there...

    It doesn't matter even a little bit where they are placed in the panel. In most dwelling units the biggest source of voltage drop when large loads are started is the utility transformer.

    For equipment that runs at or near full load 24/7, you can often get a 2-3 year payback by increasing the conductor one size, assuming that does not also require a larger conduit.
