    Yes, but this section says the EGC never has to be larger than the circuit conductors, regardless of what table 250.122 says.

    I am not sure what you mean by "not directly connected". You still...

    I looked it up. It is a 22-comm-e.

    A couple things to try.

    I have noticed that some of the AB Ethernet products don't send out their MAC ID for the BootP server to find except when the card...

    Powerflex 40 drives don't come with an Ethernet card. It is a separate card you have to add. There is an RJ45 port on powerflex 40 drives but it is not ethernet. I forget what the part number is....

    most big breakers you are supposed to do some kind of testing on now and then. if they are kept in a clean area, you can probably get by with not doing much of anything for the life of the product. I...

    Modern circuit breakers are every bit as reliable as fuses and disconnect switches if they are properly maintained. In general, they are also more cost-effective above about 200 amps most of the time...

    i agree the sections stand alone.

    However your first assertion is not quite there. neither section exempts you from running an EGC with the other conductors which is found in another section. It...

    IMO, the system grounding here refers to connecting the electrical system to earth (i.e.-creating a grounded conductor), not whether you have to route an EGC with the circuit conductors.
